Chapter 3 About the SMI ETG 3. About the SMI ETG

The SMI Eye Tracking Glasses 2w (SMI ETG) is a mobile eye tracking device with a 60 Hz / 120 Hz binocular sampling rate. It captures a user's eye movements with its high definition scene camera and special eye tracking technology.

SMI ETG

The SMI ETG is worn as a normal pair of glasses. After connecting it to an Recording Device, it is powered up and ready for use. The SMI ETG is initialized simply by having the wearer briefly fixate on one point in the environment. Two small cameras on the bottom rim of the glasses capture the eye movements of the wearer and map the wearer's gaze point into a scene video.

The SMI ETG's binocular eye tracking and automatic parallax compensation delivers reliable and accurate data over all viewing distances. With its unique interchangeable infra-red filtering lenses, the mobile eye tracker is also perfect for fully mobile outdoor tests.

The SMI ETG is provided with the following accessories:

Shaded and non-shaded infra-red filtering eye glasses

Red nose rest and Blue nose rest

Cleaning cloth

Carrying Case

3.1 Key Components

The key components of the SMI ETG are shown in the following figures.

SMI ETG front view

SMI ETG rear view

3.2 Carrying Case

The SMI ETG is stored in a protective carrying case. This case includes the two nose rests and the two Infra-Red Filtering Lenses, as well as a cleaning cloth. This Carrying Case should be used to safely store the SMI ETG when the glasses are not in use.

The SMI ETG is placed in the case with the eye cameras facing downwards.

SMI ETG in Carrying Case

3.3 Nose Rests

A set of Nose Rests are provided to adjust the SMI ETG so that the participant's eyes are positioned in the center of the eye frame.

Nose Rests for SMI ETG

When a participant's eyes are not positioned correctly, the nose rests can be adjusted up or down to center the eyes in the eye frame. Of course, using either nose rest is not necessary.

Use the nose rests in the following situations:

Narrow and pronounced noses - blue nose rest

Wider and less pronounced noses - red nose rest

Other conditions - do not use either nose rest

To insert or exchange a nose rest:

1. If the SMI ETG has a nose rest installed, carefully pull the nose rest downwards from the nose bracket to remove it.

2. Carefully insert the new nose rest into the mounting clamp until it snaps into place.

3. Correct the eye position by slightly moving the nose rest up or down.

See Checking Eye Position.

3.4 Infra-Red Filtering Lenses

The SMI ETG includes a set of shaded and non-shaded infra-red filtering lenses. These are provided to reduce IR interference caused by external light sources. SMI recommends that either the shaded or non-shaded lenses always be used:

Shaded Lenses - In bright light conditions, such as outdoor use in full sun

SMI ETG w ith Shaded Lenses

Non-Shaded Lenses - All other uses

SMI ETG w ith Non-Shaded Lenses

When interchanging the lenses do not over-bend them. To clean them, refer to Cleaning and Maintaining the SMI ETG.

3.5 Preparing the SMI ETG for Participants

To prepare the SMI ETG for a participant:

1. If not already there, insert one of the infra-red filtering lenses into the SMI ETG. (The non-shaded infra-red filtering lenses should be inserted into the glasses before shipping.) Under most conditions, the non-shaded lenses would be sufficient, but for outdoor use with bright lights, the shaded lenses may be more effective.

SMI does not recommend using the SMI ETG without one of the lenses as this can lead to reduced tracking stability.

2. Place the SMI ETG on the participant's head as you would do so with a normal pair of glasses. The temple arms should adjust to the head circumference.

Do not over-bend or fold the temple arms. Extending them beyond the mechanical stops will break the hinges. SMI will not be held responsible for damages to the frame that may affect the performance of the device. See Warnings and Precautions.

3. If the SMI ETG is not sitting correctly on the participant's nose, use one of the provided Nose Rests. See Nose Rests.

4. Tighten the head strap until the SMI ETG is firmly against the participant's head. The head strap will also prevent the SMI ETG from accidentally falling off the participant's head.

5. The participant should feel comfortable when turning his or her head, when nodding, looking around, walking, and so on.

6. Connect the SMI ETG to the ETG Tablet or to the Smart Recorder using the attached USB cable.

3.6 Cleaning and Maintaining the SMI ETG

Ensure that the camera modules are not exposed to any liquids. Do not use any water on the frame.

To clean the SMI ETG:

1. Unplug the SMI ETG from the ETG Tablet or Smart Recorder before cleaning.

2. Remove the Infra-red filtering lenses from the frame of the SMI ETG and clean the lenses with water using the supplied cleaning cloth.

3. Clean the SMI ETG frame by using a dry towel.

If the SMI ETG needs repairing:

1. In the event that your SMI ETG or a component of the system is damaged, immediately unplug the SMI ETG from the ETG Recording Device.

2. Do not attempt to repair the system yourself.

3. Servicing, adjustment or repair works must only be done by a certified distributor or by SensoMotoric Instruments GmbH (SMI).

4. Do not use the SMI ETG until the system or any of its components have been repaired.

4.2.3 Updating the ETG Tablet

The iViewETG software is available as a download from the Support area of the SMI website.

To download the latest iViewETG software:

1. Go to www.smivision.com.

2. Select Eye and Gaze Tracking Systems.

3. Select Support.

4. Select Software Download.

5. Scroll down to the iViewETG Software.

6. Click on the link to download the iViewETG installer file.

7. Download the file to your Tablet and follow the on-screen instructions to install the software.

4.3 Download Data to a PC

For all Smart Recorders delivered before November 2014, removing the Micro SD Card will invalidate the warranty. All Smart Recorders delivered AFTER November 2014 require that the Micro SD Card be removed to directly download the experiment data to BeGaze™ (an SMI label inside the device indicates which Smart Recorder you are using). This is due to a technical reason based on a newer Samsung SmartPhone S4 device used for the Smart Recorder.

Experiment data is saved to the Smart Recorder's Micro SD Card. You need copy the experiment data directly to the ETG Subnotebook (or other PC) for use by BeGaze™. Therefore, you need to remove the Micro SD card from the Smart Recorder and insert it into the SD Card slot on your PC or the ETG Subnotebook using a Micro SD Card Adapter. The data can then be copied onto your PC or the ETG Subnotebook .

To copy the data to the Smart Recorder:

Power off the Smart Recorder before continuing.

1. If connected, disconnect the SMI ETG from the Smart Recorder.

2. Lay the Smart Recorder screen-down on a soft surface such as a towel to prevent the screen from scratching.

3. Using the slot provided on the back cover near the power button, insert a fingernail into the slot and remove the cover by lifting the cover up and to the right.

Do not twist the back cover, as it might damage the cover.

4. The SD-Card slot is shown in the figure below. It is located on the upper left corner inside the ETG Smart Recorder.

Location of label on inside back of device

In the next figure you can see the SD-Card slot of the ETG Tablet.

SD-Card slot at the backside of the ETG Tablet

5. Push the Micro SD Card against the slot with your fingertip and then release. The Micro SD Card will automatically unlock and pop out from the slot. You can then easily pull out the Micro SD Card from the slot.

64 bit Micro SD Card from Smart Recorder

6. Insert the Micro SD Card into a Micro SD Card Adapter.

Micro SD Card Adapter

7. Insert the Micro SD Card Adapter into the SD Card slot of the ETG Subnotebook (or any other PC having an SD Card slot).

8. You can copy the recorded data folder to ETG Subnotebook or PC using the following methods:

a. (Recommended) Start BeGaze™ and select File > Collect Recording Unit Data. BeGaze™ automatically imports the recorded data from the Micro SD Card. Remember to delete the experiment data from the Micro SD Card after importing.

b. If BeGaze™ is running on the PC, simply drag and drop the recorded data folder into BeGaze™ to begin data analysis.

c. Alternately, you can copy the recorded data folder into a newly created folder (see note below) on your ETG Subnotebook or PC . Then start BeGaze™ and select File > New Experiment from Folder and browse for the newly created folder containing the downloaded data from the Micro SD card. Import this folder into BeGaze™ to begin data analysis.

When using an ETG Subnotebook, the data from the Smart Recorder should be stored in a newly created folder within the partition D :'\R ecorded D ata on the ETG Subnotebook.

When copying the data from the Smart Recorder's SD Card, the data will still remain in the Micro SD Card. This can lead to a full

memory which will prevent further recordings. Once you have safely copied and / or backed up your recorded data from the Micro SD Card, delete all data on the card to provide memory space for recordings.

9. Remove the Micro SD Card from the Micro SD Adapter and firmly insert the Micro SD Card back into the respective slot of the Smart Recorder.

10. Attach the back cover by pressing firmly on both sides of the cover from the top end down to the bottom end.

11. Power on the Smart Recorder and continue with your experiment recordings.

4.4 Installing iViewETG on a User PC

You can install and run iViewETG on a PC of your choice. However, the PC should at least meet the minimum hardware requirements and Windows™ settings as described in this section. A SMI-certified ETG Subnotebook with preinstalled software is available as an option.

With the SMI ETG, your PC or the SMI-certified ETG Subnotebook provides real-time observations of eye movements during data collection and, optionally, live synchronization with mobile EEG data. It allows real-time streaming and data access via the SMI SDK and enables 6D head and motion tracking support via the VRPN interface. Depending on the package purchased, data recorded with the ETG Tablet can be loaded directly into BeGaze™ Analysis Software enabling instant Retrospective Think Aloud recordings.

You should also consider that the quality of the recorded data is not assured on your own PC, which would be the case on SMI's certified ETG Tablet / Subnotebook. SMI cannot guarantee that a particular Laptop or Desktop PC running Windows 7™ or Windows 8™ will be sufficient. It is possible that hardware components or other software on a particular PC may interfere with the functioning of iViewETG software. In short, if you plan on using iViewETG on a Laptop other than the SMI-provided ETG Tablet / Subnotebook, it is possible the recording output may be a lower quality.

Remote Observation and Remote Control

Your PC or the ETG Subnotebook can also be used to remotely observe or control experiments that are running on an ETG Tablet or Smart Recorder.

Another ETG Recording Device can be remotely controlled or observed in the following combinations:

Between an User PC / ETG Subnotebook and an ETG Tablet

Between an User PC / ETG Subnotebook and a Smart Recorder

Between an User PC / ETG Subnotebook and another User PC / ETG Subnotebook

All devices must be using version 2.1 (or higher) of the iViewETG software to enable remote observation or remote control.

Experiment Settings dialog

Default Calibration Mode - You can set the default mode to be used when performing a calibration.

1-Point and 3-Point calibration modes increase the accuracy of the recording.

Options include:

o 1-Point Calibration - 1-Point Calibration is quick and easy to perform and should be your choice for fast and efficient data recording.

o 3-Point Calibration - A 3-Point Calibration can result in more accurate data, but takes more time before the experiment task can be started. In case you are not satisfied with the result of a 1-Point Calibration you might want to try using a 3-Point Calibration to get more accurate results. In most cases a 1-Point Calibration should provide the same accuracy as a 3-Point Calibration.

See Calibrating on the ETG Subnotebook

Allow Different Calibration Mode - Allows different calibration mode other than 0-Point mode. The default Calibration mode is 0-Point Calibration. You can ensure 0-Point Calibration is used by unchecking this option. To allow 1-Point or 3-Point Calibration modes, check this option.

5.4.6.5 Hardware Configuration Dialog

Accessed from the Experiment Management window, the Hardware Configuration dialog use to configure the SMI ETG for the current experiment.

Hardw are Configuration dialog

These settings determine the level of detail and quality of the recorded data from the SMI ETG. These settings are very important for obtaining optimized recordings that fit your requirements. For example, if you need to capture the smallest change in a participant's eye movement, you can set the eye sampling rate and scene camera mode to its highest resolution. But the trade-off is a large data file. If your resolution requirements are less important, you can choose a lower sample rate.

Similarly, you can set the white balance of the camera so that it optimizes for the type of ambient light available in the participant's environment.

Eye Tracking Mode - Binocular tracking is configured for Eye Tracking Mode and cannot be changed.

Eye Image Sample Rate (Sample Rate) - Select from two sample rates: o 30 Hz: slower rate which results in a smaller size data recording file. o 60 Hz: faster rate which results in a higher definition, larger data recording file.

SMI ETG V1.8 and earlier only supports 30Hz eye tracking. The version of your SMI ETG can be determined from the label on the right temple glasses' arm.

Scene Camera Sample Rate (Scene Camera Mode) - Select from two sample rates: o 24Hz (1280x960p): larger frame size but fewer (24) frames per second. This gives a higher sample rate and the widest angle of view. o 30Hz (960x720p): smaller frame size but more frames (30) per second. This gives a lower sample rate and a cropped angle of view.

SMI ETG V1.8 and earlier only supports 24Hz (1280x960p). The version of your SMI ETG can be determined from the label on the right temple glasses' arm.

Scene Camera White Balance - White balance can be adjusted automatically by the iViewETG software so that colors in the scene will match what is seen in real life. In some cases, especially under artificial light (tungsten or fluorescent), the colors of objects might not match sufficiently. You can then select a different white balance mode according to the character of the light source. Select from five options: o Automatic White Balance - Default value and provides optimal results in most cases. o Daylight (Outdoor) - If the color match in outdoor settings is distorted,

select this option.

o Incandescent (Light Bulb) - Select for white balancing "warm" light, which is primarily light from incandescent lamps that give a yellowish- orange light.

o Fluorescent - Select for white balancing "cold" light, which is primarily from fluorescent lights typical of offices, laboratories, or public places.

o Fluorescent High - Select for very bright fluorescent environments.

Microphone - The integrated microphone of the SMI ETG adds audio recording. Currently, it is activated by default and cannot be switched off.

Emotiv EEG - Enables Emotiv EEG Neuroheadset data recording.

Note that the analysis of recorded EEG data requires a special license for BeGaze™.

See Recording Screen with Emotiv EEG.

Insufficient trackability

Sufficient trackability

Trackability is not an indication of correct calibration.

Recording Time - Displays the elapsed time for the current recording.

Selected Calibration Mode - Displays the selected calibration mode. If calibration has not been performed and trackability is available, the system uses a 0-Point Calibration.

1-Point Calibration after recording

If the SMI ETG is given to another participant, you will need to manually reset the 0-Point Calibration or type in a new participant's name to automatically reset the software to obtain correct results and measurements.

Microphone - Microphone is always on and cannot be disabled. The icon is, therefore, shown as dark gray.

3-Step Confirmation - indicates the status of three key tasks: o Participant properties set. o Calibration performed. o Data recorded and saved.

Grayed out icons indicate the task has not been completed.

Tasks not completed

As each task is completed, the icon turns to dark gray to confirm task completion.

Chapter 6 iView ETG User Guide 6. Using Direct Gaze

Direct Gaze mode is the default recording mode in both the ETG 2 Observation and ETG 2w Observation packages. This mode provides recordings of the scene view with a gaze cursor overlay. These recordings can then be viewed in VLC Media Player for immediate review. However, they cannot be imported into BeGaze™ for analysis.

In this mode, a video of the scene with a gaze cursor will be recorded with one .avi file per recording. This recording will be saved to the Quick R un And D irect Gaze repository. If a participant is created, then a folder will be created in this repository with the name of the participant. In this folder, each new recording (.avi) will be added to this folder.

The SMI ETG provided with ETG 2 Observation and ETG 2w Observation has a sample rate that is fixed at 30 Hz and a Scene Camera Mode fixed at 24 FPS.

Quick Run Settings File

Direct Gaze mode makes use of the Quick Run settings in the Quick R un.etg file to output recording data. These settings can only be modified if you are using the ETG 2w Analysis and ETG 2w Analysis Pro packages. If you change Quick Run settings before using Direct Gaze, these two settings will not be changed.

Chapter 10 iView ETG User Guide 10. Performing a Calibration

Calibration is an important process that ensures the quality of the recording. It ensures the gaze of the participant is accurately tracked throughout the scene.

About Calibration

Calibrating is the process whereby the SMI ETG establishes the relationship between the position of the eye in the camera view and the gaze point is space, the so-called Point of Regard (POR). Calibration establishes the plane in space where eye movements are rendered. Since this relationship strongly depends on the overall system setup and also varies between subjects, a reference measurement called Calibration must be performed before each experiment.

During calibration, a participant is presented with a number of targets (either 1-point or 3-points) of known locations. These targets must be fixated by the participant and the position of the eyes is noted in iViewETG. In short, the accuracy of the gaze data is directly related to the success of the calibration.

Calibration Modes

Three calibration options are available:

0-Point Calibration - This is the default calibration mode. A 0-Point Calibration will be performed as soon as the eyes of the participant can be tracked and after the Recording window is displayed. To allow a recording with 0-Point Calibration, ensure that Make Calibration Mandatory is unchecked in the Experiment Settings dialog.

1-Point Calibration - This is a single point fixation resulting in good accuracy. 1-Point Calibration is quick and easy to perform and should be your choice for fast and efficient data recording.

3 - Point Calibration - This is a three point fixation resulting in higher

accuracy. In case you are not satisfied with the result of a 1-Point Calibration use a 3-Point Calibration to get a more accurate result. In most cases a 1-Point Calibration should provide the same accuracy as a 3-Point Calibration.

Internal Eye Model

A calibration causes the internal eye model of the iViewETG software to adapt the participant's eyes. Otherwise, the gaze cursor may become unstable and not track the participant's eyes properly. This will lead to incorrect results.

The internal eye model needs to be completely adapted to the participant's actual eye movements. This process is accompanied by a change of the gaze cursor color from red (internal SMI eye model) to green (participant’s eye model). If no adaptation of the internal SMI eye model is necessary, the gaze cursor remains red indicating that the internal eye model is the best fit to the participant's eyes.

Adding a new participant will reset the internal eye model to 0-Point Calibration.

It is very important to provide a name for New Participant whenever a new participant starts wearing the SMI ETG. This will adapt the internal eye model to the participant's eyes. Otherwise the gaze cursor may not stabilize and the results will be incorrect.

You can also perform an off-set correction using BeGaze™ Analysis Software. For more information, see the BeGaze™ Analysis Software User Guide.

10.1 Calibrating on the Smart Recorder

To perform a calibration on the Smart Recorder:

1. After entering the Recording window, a 0-Point Calibration will be automatically performed. See Default 0-Point Calibration Mode.

2. The gaze cursor will locate itself at a location iViewETG estimates where the participant is looking.

3. Tap the Calibrate button to show the Calibration screen.

Normally, after tapping on the Calibration button, the Add Participant screen appears to associate a participant with the calibration and the recording.

Add Participant screen

4. Select either 1-Point Calibration or 3-Point Calibration.

Select calibration mode

5. Select a target point in the field of view and ask the participant to focus on this point.

This point should, ideally, be at a distance of about 1.5m between the participant and the calibration object. Your participant should sit or stand comfortably while looking straight ahead without moving the head. The object should be at the middle of the scene camera image for optimal accuracy.

6. Tap on the screen to pause at the last estimated gaze point. The Gaze cursor will change to a Crosshair Cursor.

Simply tapping in the Gaze Scene pauses the video. Then a position marker can be dragged over the screen to the desired position. Releasing the finger accepts the point. A check mark on the corresponding Calibration button indicates whether a calibration has been performed.

The Crosshair Cursor is active for 90 seconds. If the calibration point is not accepted within this period, the calibration is canceled.

7. Move the Crosshair Cursor to the dedicated target point.

Crosshair cursor moved to gaze point

8. Click Accept to continue or Cancel to perform the calibration again.

9. The color of the Gaze Cursor will turn to green.

10.When all required points are defined, the calibration is complete and is applied by the software.

See Gaze Points for 3-Point Calibration.

11.The gaze calibration can now be validated by looking at the live preview. If the data quality is acceptable after calibration, click Record to continue.

10.2 Calibrating on the ETG Tablet / Subnotebook

To perform a calibration on the ETG Tablet / Subnotebook:

1. After entering the Recording window, a 0-Point Calibration will be automatically performed. See Default 0-Point Calibration Mode.

If calibration cannot be done, a warning will appear indicating iViewETG cannot track the participant's eyes. Ensure the SMI ETG is worn correctly. See Wearing the SMI ETG.

2. The Gaze Cursor will locate itself at the location iViewETG estimates where the participant is looking.

Gaze Cursor

3. Select a target point in the field of view and ask the participant to focus on this point.

This point should, ideally, be at a distance of about 1.5m between

the participant and the calibration object. Your participant should sit or stand comfortably while looking straight ahead without moving the head. The object should be at the middle of the scene camera image for optimal accuracy.

4. Select 1-Point Calibration or 3-Point Calibration from the drop down menu and click the button to start the calibration.

Select calibration mode

5. In the scene view, move the mouse cursor over the scene view. This will change the Gaze Cursor to to a Crosshair cursor.

6. Move the Crosshair cursor to the target point.

The numbers below Crosshair Cursor will show which calibration point you are currently using. These numbers include the calibration mode (right) and the number of points remaining to calibrate (left). In case of the 1-Point Calibration this number will be 1/1. In case of the first point of a 3-Point Calibration this number will be 1/3.

7. The Gaze Cursor's offset will now be corrected to the Crosshair Cursor’s position and will change to a Gaze Cursor.

Validate the accuracy of this calibration by asking your participant to look at different objects from their present location. Ideally, choose some objects nearby and at the distance you want to measure.

8. If 3-Point Calibration was selected, continue with the remaining 2 points.

See Gaze Points for 3-Point Calibration.

9. If the gaze cursor matches the objects, you can continue by starting the recording session. Otherwise, you may retry the 1-Point Calibration or run a 3-Point Calibration.

To abort a calibration, click the highlighted calibration button again.

10.With the SMI ETG now accurately tracking the eye gaze of the participant, you are now ready to start your recording session.

10.3 About 0-Point Calibration Mode

0-Point Calibration is the default calibration mode. If calibration has not been performed and trackability is available, the system uses 0-Point Calibration, which is the default calibration mode.

After entering the recording screen, a 0-Point Calibration is automatically performed based on an internal SMI eye model:

1. At the beginning of this calibration period, the gaze cursor is shown in red, indicating that the internal SMI eye model is active.

2. During the next 30 seconds, iViewETG attempts to adapt the eye model to the participant's actual eye movements.

Ensure that the participant is moving the eyes around during this calibration phase to ensure better adaptation of the model.

3. As optimization progresses, the color of the gaze cursor color changes from red to green.

In case you do not see a gaze cursor and/or the warning Insufficient trackability of the subject appears, check for gaze cursor stabilization and check if the ETG is worn by the participant. See Gaze Cursor Stabilization.

4. After the ETG Recording Device performs the 0-Point Calibration, you can begin recording.

Should the 0-Point Calibration not provide sufficient results and the gaze cursor does not match the participants real gaze position, you can use 1 or 3-Point Calibration.

Reset to 0-Point Calibration

If the SMI ETG is given to another participant, you will need to manually reset to 0-Point Calibration or type in a new participant's name to automatically reset iViewETG to 0-point calibration. This is necessary to obtain correct results and measurements.

10.4 About 1 Point Calibration Mode

1-Point Calibration is a single point fixation resulting in good accuracy. It is quick and easy to perform. It should be your choice for fast and efficient data recording.

10.5 About 3-Point Calibration Mode

3-Point Calibration is a three point fixation resulting in higher accuracy.

In principal, a 3-Point Calibration should use a triangular position of gaze points, which are on the same plane. (See the two figures below). Do not try to calibrate by using 3 points in a row and / or at different distances from

Chapter 11 Defining and Applying Annotations 11. Defining and Applying Annotations

Annotations are used to associate an event or item with a specific time or duration of a recording. Annotations are defined during experiment setup and applied during a recording. Annotations are part of the Experiment Definition and are saved in the experim ent.xm l.

Local annotations can be added on the Smart Recorder or User PC / ETG Subnotebook. In experiments running on the ETG Tablet, you can add annotations via Remote Control.

In this section:

For a description of annotations, see Annotation Types.

To define an annotation on the Smart Recorder, see Annotations on the Smart Recorder;

To define an annotation on the ETG Subnotebook, see Annotations on the ETG Subnotebook.

To define a tag, see Defining Tags

To apply an annotation on the Smart Recorder, see Applying an Annotation on the Smart Recorder

To apply an annotation on the ETG Subnotebook, see Applying an Annotation on the Smart Recorder.

11.1 Defining Annotations

Annotations can be defined as either an instant or an Interval annotation.

Instant Annotations - Instant annotations are discrete moments in time: "At this particular m om ent (or tim estam p), this action occurred." Instant annotations are applied at specific timestamps during a recording, that is, at the moment the defined event occurs.

Interval Annotations (Manual On/Off, Until Same Tag) - Interval annotations are undefined spans of time: "From this point in tim e (at this tim estam p) to this point in tim e (at this tim estam p) this action occurred." Interval annotations have a specific start and end time. Once applied, an interval annotation ends either manually (by pressing a key) or by selecting another annotation that uses the same tag.

A tag can be associated with each annotation. Tags are meta-data that you associate with one or more annotations. For example, you could define a tag as a "Location" to group sets of annotations related to the location of a participant within the experiment's zone of interest.

During a recording free text can be added to any annotation. This text is a textual markers that can be added in place of an Instant or Interval annotation.

The following table describes the properties of an annotation.

Chapter 12 iView ETG User Guide 12. Remote Observation and Control

Before Using Remote Observation or Remote Control, a wired or wireless connection must be made between all the devices to be used remotely.

Device Combinations

Remote Observation and Remote Control can only be done with the following device combinations:

Between an ETG Subnotebook running the iViewETG 2.1 (or higher) software and another ETG Subnotebook running the iViewETG 2.1 (or higher) software

Between an ETG Subnotebook running the iViewETG 2.1 (or higher) software and an Smart Recorder running the iViewETG Mobile 2.1 (or higher) software

Remote Controller Recording Device

ETG Subnotebook ETG Subnotebook

ETG Subnotebook Smart Recorder

12.1 Networking for Remote Use

Networking

To use Remote Control or Remote Observation, the ETG Subnotebook needs to connect to the ETG Recording Device via a network. This usually means both devices need to be in the same network. It is irrelevant if one of the devices is plugged in via cable or has wireless access. What is important is that they can connect to each other. They must be in the same LAN, in the same subnet, and the devices must not be blocked via a firewall.

Possible Network Setups

Ad-Hoc WiFi Network

The ETG Subnotebook creates an Ad-Hoc WiFi Network, which an Smart Recorder and/or another ETG Subnotebook can use to connect with the ETG Subnotebook. The advantage of this type of connection is that no other hardware is required, such as a WLAN wireless router. However, the range is limited.

Wireless/Wired Network via a router

In this case, a router is used to create the wireless or wired network. Ideally, the ETG Subnotebook should be plugged into the router via a LAN cable while the remote devices are connected wirelessly. The advantage is that the ETG Subnotebook does not take any wireless "bandwidth" and leaves it for the remote devices and the router. Of course, the ETG Subnotebook can be connected wirelessly to the router as well. However, since the ETG Recording Devices are mobile, ideally they should be connected wirelessly.

An advantage of this configuration is that the range (distance between devices) is greatly extended compared to an Ad-Hoc WiFi network connection.

Corporate or Enterprise LAN Network

In this case, a LAN network is usually already available. Both the ETG Subnotebook and the ETG Recording Device are connected to the LAN network and are assigned IP addresses. Contact your system administrator for assistance.

12.2 Setting Up an Ad-Hoc WiFi Connection

A recording on the Smart Recorder can be remotely observed or controlled by an experiment leader who is using a PC or the ETG Subnotebook. In this case, the participant need only be concerned about following the tasks designed by the experiment leader.

Remote control and remote observation uses either a wired or wireless connection between the devices. The iViewETG software provides a convenient, built-in Ad-Hoc WiFi network to connect the ETG Recording Devices without any need for external components such as a WLAN router.

To make this connection, follow these steps.

To set up the Ad-Hoc WiFi network:

1. In the Connection window of the PC / ETG Subnotebook, Click Ad-Hoc WiFi.

Ad-Hoc WiFi

2. In the Ad-Hoc WiFi Network Settings dialog that appears, enter a Network name (or accept the default name) and Password (or accept the default password).

Ad-Hoc Wifi Settings dialog

3. Click Start Ad-Hoc Network. After a few moments, the network will start and this dialog will disappear.

4. The Smart Recorder now automatically connects to your established Ad- Hoc Network. If not, please select your network manually via the WiFi settings icon in the options menu.

Options menu show ing IP Address

5. On the Connection window of the PC / ETG Subnotebook, click either Observe a Remote ETG or Control a Remote ETG.

Chapter 13 iView ETG User Guide 13. Gaze Cursor Stabilization

A stable gaze cursor is necessary for an experiment to be run. In some cases when a participant is trying to focus on a stimulus, some unexpected behavior can occur or a warning "insufficient trackability of the subject" may appear.

These behaviors and warnings indicate that insufficient information is available about the participant's eye movement and is disturbed due to one or more of the following reasons:

0-Point Calibration has not been reset or failed to reset. See 0-Point Calibration.

The eye position in the frame of the SMI ETG is not correct. See Eye positioning.

The participant has monocular vision. See Monocular vision.

Distortion could be caused by eye makeup, such as mascara or eyeliner. See Eye makeup.

The participant may have extreme ocular dominance of one eye. See Ocular dominance.

IR reflections may be distracting to the participant. See Distracting IR reflections.

The participant may be wearing corrective glasses between the SMI ETG and the participant's eye. See Corrective Glasses.

The participant may be wearing contact lenses. See Contact lenses.

13.1 Checking Eye Position

The SMI ETG is designed to fit most participants when using the standardized nose rests. The eye position in the SMI ETG can be seen by activating the Eye Video Display in the Recording Window.

To correct the eye position:

1. Stop any recording, as the eye images can only be displayed when no recording is performed. When you start a recording, iViewETG will automatically turn off the Eye Video Display.

Eye Video Display Off

2. Move the Eye Video Display slider to the right to activate the Eye Video Display.

3. The position of the eyes as recognized by the SMI ETG will be displayed, showing both left and right eye images.

Eye Video Display on

4. If the eye images are not centered, use a different nose rest to adapt the eye position. See Nose Rests.

5. Continue with the recording.

13.2 Participant has Monocular Vision

The SMI ETG is a binocular mobile eye tracking device and tracks both eyes of a participant. In cases of monocular vision, such as due to an artificial eye, the system will not receive enough information to calculate the gaze position and the system will not acquire sufficient tracking information for that particular participant.

13.3 Make Up

The SMI ETG uses infrared light during the eye tracking process. In some cases, eye makeup (especially mascara) may disturb correct measurements. Ask your participant to remove any eye makeup before running the experiment

13.4 Participant has Ocular Dominance

In binocular vision, a dominant eye is an eye which the brain primarily relies upon for positional information. If, however, this dominant eye becomes over-dom inant, this normal effect can sometimes interfere with the SMI ETG measurement model. In these cases, the system will not acquire sufficient tracking information for that particular participant.

13.5 Distracting IR Reflection

Always use the Convertible Lenses delivered with the SMI ETG to avoid distracting IR reflection from external sources in your participant's eyes. This distraction may lead to inaccurate eye tracking or loss of trackability. In extremely bright light conditions it may be necessary to block IR light from above by wearing a cap or something similar above the glasses.

See Convertible Lenses, Corrective Glasses, and Contact Lenses

13.6 Use of Corrective Glasses

The SMI ETG hardware is not designed for use with normal corrective glasses. The inclusion of a participant who wears corrective glasses needs to be decided upon on a case by case basis.

13.7 Use of Contact Lenses

In most cases, soft and hard contact lenses work perfectly well with the SMI ETG. In some cases, contact lenses may disturb correct tracking results. Should you encounter problems, ask your participant to remove them, if possible.

Chapter 14 Experiment Repositories 14. Experiment Repositories

iViewETG provides two repositories:

Experiment repository

Quick Run and Direct Gaze repository

Experiment Repositories w indow

The experiment files (*.etg) contain all necessary information about the experiment. Do not delete or remove any of these files!

Data is stored differently, depending on whether Experiment Run or Quick Run / Direct Gaze are used.

Data from experiments is stored in either an initial directory preset by SMI or in a selected directory. The data from each unique participant is stored in a directory that is identified with the participant's name along with a unique directory name hash. Consequently, no naming conflict will occur if you

14.1 Experiment Run Repository

When using an experiment created, dedicated settings are required. These settings are saved to the root of the Experiment repository while the recording data of all participants using this experiment are saved in one experiment folder.

Default Experiment repository path set to:

D :\R ecorded D ata\Experim ent D ata\

Each experiment is saved to its own named directory:

D :\R ecorded D ata\Experim ent D ata\Experim ent N am e\Experim ent N am e.etg

Data of each participant using a specific experiment is saved to its own named directory:

D :\R ecorded D ata\Experim ent D ata\Experim ent N am e\Participant N am e\

This folder contains a number of participant related xml files, video and audio recordings (.avi and .wav files), and codec files.

The experiment files (*.etg) contain all the necessary information about the experiment for analysis. Do not delete or remove any of these files!

See also Changing the Data Storage Directory.

14.2 Quick Run And Direct Gaze Repository

Both Quick Run or Direct Gaze use the same settings file Quick R un.etg. This file is located in the root of the repository. The data for each participant using Quick Run or Direct Gaze is saved to one folder. Direct Gaze data, however, cannot be analyzed using BeGaze™.

The default Quick Run and Direct Gaze repository path is set to:

D :\R ecorded D ata\

The data of each participant using Quick Run or Direct Gaze is saved to its own folder:

D :\R ecorded D ata\Participant N am e\

This folder contains a number of participant related XML files, video and audio recordings (.avi and .wav files), and CODEC files.

The experiment file Quick R un.etg contain all necessary settings for running a Quick Run or Direct Gaze experiment. Do not delete or remove this file!

See also Changing the Data Storage Directory.

14.3 Changing Data Storage Directory

14.5 Video and Audio Files

Your experiment contains three video files and one audio file. The audio file will be saved as a .wav file. Two video files (.avi) are down-sampled eye videos of the right and left eye respectively, which are provided for support purposes only.

Chapter 15 iView ETG User Guide 15. Connecting an Interface to the iViewETG

The iViewETG is capable of interfacing with various external hardware and software through either of the following:

Parallel Port Interfacing

Software Interfacing over UDP

iViewETG SDK

See iViewETG SD K Manual

15.1 Parallel Port Interfacing

The iViewETG is capable of receiving TTL signals through a parallel port input.

Reading LPT data is officially supported only on X230 laptops (the ETG Subnotebook) and with a LPT PCMCIA card. Reading LPT data is not supported on other platforms.

15.1.1 Connecting to a Parallel Port

Please note that this feature is only available on the ETG Subnotebook. iViewETG supports only a PCI Express Card provided by SMI.

For further information contact your SMI sales representative. See Contacting SMI. Before using the LPT port, make sure that your ETG Subnotebook has the dedicated LPT port adapter installed.

DeLock PCI Express Card and LPT connector

To connect to a parallel Port:

1. Insert the PCI Express Card into the PCI card slot on the ETG Subnotebook.

installing the PC Card correctly to the SMI-ETG Laptop.

2. Attach the LPT Connector to the inserted PC Card.

3. No further configuration is necessary.

15.1.2 TTL I/O for LPT Parallel Port Adapter

Four lines of the LPT port can be used as input, as given in the following table:

Pin number

To check if TTL signals are received in iViewETG you can use the "Event Log". To enable "Event Log" make sure that "Show Event Log" is checked in the settings of the experiment in use.

"Show Event Log" enabled in iView ETG Recording Screen

TTL signals will be timestamped and stored together with the recorded data in a file ending on *-ttl.xml. When loading the recorded data in BeGaze TTL signals will be shown as well.

15.1.3 Export of LPT Trigger Signals

TTL signals will be timestamped and recorded in an additional file appended with -ttl.xm l.

The BeGaze™ raw data export adds an additional Trigger column. The value in the Trigger column is a decimal numerical representation of the digital input.

15.2 Software Interfacing over UDP

Sometimes it is desirable to cooperate with other measurement applications like motion tracking or eeg systems in mobile sensor networks while recording gaze tracking.

With UDP (User Datagram Protocol) computer applications can send messages to other hosts on a network. The iViewETG is capable of receiving trigger messages through UDP.

UDP messages are string messages with maximal 256 characters.

15.2.1 UDP Trigger Support

In order to synchronize multiple data streams in a network and to be able to map external events to the time line of iViewETG you can send messages from your own application to the iViewNG-Server via UDP. The port 4444 is the default port the iViewNG-Server listens to.

Received messages will be stored in a file *-text.xml with a timestamp in the same repository of the recorded data. Note: Only while a recording is running the received messages will be written into the *-text.xml - file.

In case the port number 4444 is reserved for another application, then you have to define a different port number by creating a txt-file named "udp-trigger-port.txt" in the recorded data repository (on Android in the folder "/storageextSdCard/). In this "udp-trigger-port.txt" file insert your own port number. If the iViewNG-Server finds a file "udp-trigger-port.txt", it expects to find a port number there. A port number of zero will switch off listening for messages.

For more information please refer to iViewETG SD K Manual.

15.2.2 Export of UDP Trigger messages

The received UDP messages are available for further analysis in BeGaze™ and other applications.

For more information please refer to BeGaze Manual.

Chapter 16 iView ETG User Guide 16. Troubleshooting

This section contains a list of Frequently Asked Questions (FAQ) and a description of the Issue Reporting Tool.

16.1 FAQ

The following are some of the most commonly asked questions about the SMI ETG:

It seem s like the SMI ETG is taking a long tim e to start up.

Note that the SMI ETG needs time to boot. Be patient and allow all subsystems to initialize correctly. This may take up to 30 seconds. In problematic cases, quit the iViewETG software and restart. If this has no effect, disconnect the SMI ETG and reboot the ETG Subnotebook. Reconnect the SMI ETG and start the iViewETG software. If the problem persists, then use the Create Issue Report function and forward the generated zip-folder to SMI Support for further advice and assistance.

W ill the ETG Subnotebook go into Sleep Mode?

During recording sessions you can close the ETG Subnotebook. It will not go into sleep mode. In any other case, avoid activating the sleep mode while the device is plugged into the USB port. Reboot the complete system if the ETG Subnotebook went into sleep mode and you notice instability of the gaze cursor or if the SMI ETG does not respond correctly to the iViewETG software.

The iViewETG software does not detect the SMI ETG.

If, in any case, the iViewETG software does not detect the SMI ETG correctly, disconnect the SMI ETG, quit the iViewETG software, reconnect the SMI ETG, and then restart the iViewETG software.

Should I use the ETG Subnotebook when the battery is low, say below 10% charged?

When the ETG Subnotebook battery has been discharged to less than 10% capacity, first recharge the battery to more than 20% capacity before operating the iViewETG software again.

W hat happens if the SMI ETG is disconnect during a recording?

If the SMI ETG is disconnected during a recording, you must restart the Smart Recorder to resume the experiment recording.

It is possible the data from the last recording may have been corrupted so a new recording should take place.

16.2 Issue Reporting Tool

In each window in the iViewETG software, a Create Issue Report button is available that launches the Issue Reporting Tool for describing problems should they occur. If an unforeseen problem occurs with the iViewETG software, click on the Create Issue Report button for reporting the issue.

Create Issue Reporting tool

The Create Issue Report tool opens a text window for providing an additional issue description. Additionally the Create Issue Report tool automatically acquires a screen shot of the whole screen and the log-file belonging to this session. All data are merged into a zip folder and stored on the Desktop of the ETG Subnotebook, usually through a Save As...,.

If you require assistance from the SMI support related to a failure of the system, please forward the generated zip folder to the SMI support for further advice and help by email.

As used herein, “this License” ref ers to v ersion 3 of the GNU Lesser General Public License, and the “GNU GPL” ref ers to v ersion 3 of the GNU General Public License.“The Library ” ref ers to a cov ered work gov erned by this License, other than an Application or a Combined Work as def ined below. An “Application” is any work that makes use of an interf ace prov ided by the Library , but which is not otherwise based on the Library . Def ining a subclass of a class def ined by the Library is deemed a mode of using an interf ace prov ided by the Library . A “Combined Work” is a work produced by combining or linking an Application with the Library . The particular v ersion of the Library with which the Combined Work was made is also called the “Linked Version”.The “Minimal Corresponding Source” f or a Combined Work means the Corresponding Source f or the Combined Work, excluding any source code f or portions of the Combined Work that, considered in isolation, are based on the Application, and not on the Linked Version. The “Corresponding Application Code” f or a Combined Work means the object code and/ or source code f or the Application, including any data and utility programs needed f or reproducing the Combined Work f rom the Application, but excluding the Sy stem Libraries of the Combined Work.

2. Exception to Section 3 of the GNU GPL. You may conv ey a cov ered work under sections 3 and 4 of this License without being bound by section 3 of the GNU GPL.

3. Conv ey ing Modif ied Versions. If y ou modif y a copy of the Library , and, in y our modif ications, a f acility ref ers to a f unction or data to be supplied by an Application that uses the f acility (other than as an argument passed when the f acility is inv oked), then y ou may conv ey a copy of the modif ied v ersion: a) under this License, prov ided that y ou make a good f aith ef f ort to ensure that, in the ev ent an Application does not supply the f unction or data, the f acility still operates, and perf orms whatev er part of its purpose remains meaningf ul, or b) under the GNU GPL, with none of the additional permissions of this License applicable to that copy .

the Library and its use are cov ered by this License. b) Accompany the object code with a copy of the GNU GPL and this license document.

5. Combined Works. You may conv ey a Combined Work under terms of y our choice that, taken together, ef f ectiv ely do not restrict modif ication of the portions of the Library contained in the Combined Work and rev erse engineering f or debugging such modif ications, if y ou also do each of the f ollowing: a) Giv e prominent notice with each copy of the Combined Work that the Library is used in it and that the Library and its use are cov ered by this License. b) Accompany the Combined Work with a copy of the GNU GPL and this license document. c) For a Combined Work that display s copy right notices during execution, include the copy right notice f or the Library among these notices, as well as a ref erence directing the user to the copies of the GNU GPL and this license document. d) Do one of the f ollowing

Conv ey the Minimal Corresponding Source under the terms of this License, and the Corresponding Application Code in a f orm suitable f or, and under terms that permit, the user to recombine or relink the Application with a modif ied v ersion of the Linked Version to produce a modif ied Combined Work, in the manner specif ied by section 6 of the GNU GPL f or conv ey ing Corresponding Source.

Use a suitable shared library mechanism f or linking with the Library . A suitable mechanism is one that (a) uses at run time a copy of the Library already present on the user's computer sy stem, and (b) will operate properly with a modif ied v ersion of the Library that is interf ace- compatible with the Linked Version. e) Prov ide Installation Inf ormation, but only if y ou would otherwise be required to prov ide such inf ormation under section 6 of the GNU GPL, and only to the extent that such inf ormation is necessary to install and execute a modif ied v ersion of the Combined Work produced by recombining or relinking the Application with a modif ied v ersion of the Linked Version. (If y ou use option 4d0, the Installation Inf ormation must accompany the Minimal Corresponding Source and Corresponding Application Code. If y ou use option 4d1, y ou must prov ide the Installation Inf ormation in the manner specif ied by section 6 of the GNU GPL f or conv ey ing Corresponding Source.)

6. Combined Libraries. You may place library f acilities that are a work based on the Library side by side in a single library together with other library f acilities that are not Applications and are not cov ered by this License, and conv ey such a combined library under terms of y our choice, if y ou do both of the f ollowing:

a) Accompany the combined library with a copy of the same work based on the Library , uncombined with any other library f acilities, conv ey ed under the terms of this License. b) Giv e prominent notice with the combined library that part of it is a work based on the Library , and explaining where to f ind the accompany ing uncombined f orm of the same work.

17.4.4 GNU General Public License version 3

Version 3, 29 June 2007

Ev ery one is permitted to copy and distribute v erbatim copies of this license document, but changing it is not allowed.

PREAMBLE

The GNU General Public License is a f ree, copy lef t license f or sof tware and other kinds of works.

The licenses f or most sof tware and other practical works are designed to take away y our f reedom to share and change the works. By contrast, the GNU General Public License is intended to guarantee y our f reedom to share and change all v ersions of a program to make sure it remains f ree sof tware f or all its users. We, the Free Sof tware Foundation, use the GNU General Public License f or most of our sof tware; it applies also to any other work released this way by its authors. You can apply it to y our programs, too.

When we speak of f ree sof tware, we are ref erring to f reedom, not price. Our General Public Licenses are designed to make sure that y ou hav e the f reedom to distribute copies of f ree sof tware (and charge f or them if y ou wish), that y ou receiv e source code or can get it if y ou want it, that y ou can change the sof tware or use pieces of it in new f ree programs, and that y ou know y ou can do these things.

To protect y our rights, we need to prev ent others f rom deny ing y ou these rights or asking y ou to surrender the rights. Theref ore, y ou hav e certain responsibilities if y ou distribute copies of the sof tware, or if y ou modif y it: responsibilities to respect the f reedom of others.

For example, if y ou distribute copies of such a program, whether gratis or f or a f ee, y ou must pass on to the recipients the same f reedoms that y ou receiv ed. You must make sure that they , too, receiv e or can get the source code. And y ou must show them these terms so they know their rights.

Dev elopers that use the GNU GPL protect y our rights with two steps: (1) assert copy right on the sof tware, and (2) of f er y ou this License giv ing y ou legal permission to copy , distribute and/or modif y it.

For the dev eloper’s and author’s protection, the GPL clearly explains that there is no warranty f or this f ree sof tware. For both user’s and author’s sake, the GPL requires that modif ied v ersions be marked as changed, so that their problems will not be attributed erroneously to authors of prev ious v ersions.

Some dev ices are designed to deny users access to install or run modif ied v ersions of the sof tware inside them, although the manuf acturer can do so. This is f undamentally incompatible with the aim of protecting user’s f reedom to change the sof tware. The sy stematic pattern of such abuse occurs in the area of products f or indiv iduals to use, which is precisely where it is most unacceptable. Theref ore, we hav e designed this v ersion of the GPL to prohibit the practice f or those products. If such problems arise substantially in other domains, we stand ready to extend this prov ision to those domains in f uture v ersions of the GPL, as needed to protect the f reedom of users.

Finally , ev ery program is threatened constantly by sof tware patents. States should not allow

patents to restrict dev elopment and use of sof tware on general-purpose computers, but in those that do, we wish to av oid the special danger that patents applied to a f ree program could make it ef f ectiv ely proprietary . To prev ent this, the GPL assures that patents cannot be used to render the program non-f ree.

The precise terms and conditions f or copy ing, distribution and modif ication f ollow.

TERMS AND CONDITIONS

1. Def initions. "This License" ref ers to v ersion 3 of the GNU General Public License. “Copy right” also means copy right-like laws that apply to other kinds of works, such as semiconductor masks. “The Program” ref ers to any copy rightable work licensed under this License. Each licensee is addressed as “y ou”. “Licensees” and “recipients” may be indiv iduals or organizations. To “modif y ” a work means to copy f rom or adapt all or part of the work in a f ashion requiring copy right permission, other than the making of an exact copy . The resulting work is called a “modif ied v ersion” of the earlier work or a work “based on” the earlier work. A “cov ered work” means either the unmodif ied Program or a work based on the Program. To “propagate” a work means to do any thing with it that, without permission, would make y ou directly or secondarily liable f or inf ringement under applicable copy right law, except executing it on a computer or modif y ing a priv ate copy . Propagation includes copy ing, distribution (with or without modif ication), making av ailable to the public, and in some countries other activ ities as well. To “conv ey ” a work means any kind of propagation that enables other parties to make or receiv e copies. Mere interaction with a user through a computer network, with no transf er of a copy , is not conv ey ing. An interactiv e user interf ace display s “Appropriate Legal Notices” to the extent that it includes a conv enient and prominently v isible f eature that (1) display s an appropriate copy right notice, and (2) tells the user that there is no warranty f or the work (except to the extent that warranties are prov ided), that licensees may conv ey the work under this License, and how to v iew a copy of this License. If the interf ace presents a list of user commands or options, such as a menu, a prominent item in the list meets this criterion.

2. Source Code. The “source code” f or a work means the pref erred f orm of the work f or making modif ications to it. “Object code” means any non-source f orm of a work. A “Standard Interf ace” means an interf ace that either is an of f icial standard def ined by a recognized standards body , or, in the case of interf aces specif ied f or a particular programming language, one that is widely used among dev elopers working in that language. The “Sy stem Libraries” of an executable work include any thing, other than the work as a whole, that (a) is included in the normal f orm of packaging a Major Component, but which is not part of that Major Component, and (b) serv es only to enable use of the work with that Major Component, or to implement a Standard Interf ace f or which an implementation is av ailable to the public in source code f orm. A “Major Component”, in this context, means a major essential component (kernel, window sy stem, and so on) of the specif ic operating sy stem (if any ) on which the executable work runs, or a compiler used to produce the work, or an object code interpreter used to run it. The “Corresponding Source” f or a work in object code f orm means all the source code needed

to generate, install, and (f or an executable work) run the object code and to modif y the work, including scripts to control those activ ities. Howev er, it does not include the work’s Sy stem Libraries, or general-purpose tools or generally av ailable f ree programs which are used unmodif ied in perf orming those activ ities but which are not part of the work. For example, Corresponding Source includes interf ace def inition f iles associated with source f iles f or the work, and the source code f or shared libraries and dy namically linked subprograms that the work is specif ically designed to require, such as by intimate data communication or control f low between those subprograms and other parts of the work. The Corresponding Source need not include any thing that users can regenerate automatically f rom other parts of the Corresponding Source. The Corresponding Source f or a work in source code f orm is that same work.

3. Basic Permissions. All rights granted under this License are granted f or the term of copy right on the Program, and are irrev ocable prov ided the stated conditions are met. This License explicitly af f irms y our unlimited permission to run the unmodif ied Program. The output f rom running a cov ered work is cov ered by this License only if the output, giv en its content, constitutes a cov ered work. This License acknowledges y our rights of f air use or other equiv alent, as prov ided by copy right law. You may make, run and propagate cov ered works that y ou do not conv ey , without conditions so long as y our license otherwise remains in f orce. You may conv ey cov ered works to others f or the sole purpose of hav ing them make modif ications exclusiv ely f or y ou, or prov ide y ou with f acilities f or running those works, prov ided that y ou comply with the terms of this License in conv ey ing all material f or which y ou do not control copy right. Those thus making or running the cov ered works f or y ou must do so exclusiv ely on y our behalf , under y our direction and control, on terms that prohibit them f rom making any copies of y our copy righted material outside their relationship with y ou. Conv ey ing under any other circumstances is permitted solely under the conditions stated below. Sublicensing is not allowed; section 10 makes it unnecessary .

4. Protecting Users’ Legal Rights From Anti-Circumv ention Law. No cov ered work shall be deemed part of an ef f ectiv e technological measure under any applicable law f ulf illing obligations under article 11 of the WIPO copy right treaty adopted on 20 December 1996, or similar laws prohibiting or restricting circumv ention of such measures. When y ou conv ey a cov ered work, y ou waiv e any legal power to f orbid circumv ention of technological measures to the extent such circumv ention is ef f ected by exercising rights under this License with respect to the cov ered work, and y ou disclaim any intention to limit operation or modif ication of the work as a means of enf orcing, against the work’s users, y our or third parties’ legal rights to f orbid circumv ention of technological measures.

5. Conv ey ing Verbatim Copies. You may conv ey v erbatim copies of the Program’s source code as y ou receiv e it, in any medium, prov ided that y ou conspicuously and appropriately publish on each copy an appropriate copy right notice; keep intact all notices stating that this License and any non-permissiv e terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty ; and giv e all recipients a copy of this License along with the Program. You may charge any price or no price f or each copy that y ou conv ey , and y ou may of f er support or warranty protection f or a f ee.

6. Conv ey ing Modif ied Source Versions. You may conv ey a work based on the Program, or the modif ications to produce it f rom the Program, in the f orm of source code under the terms of section 4, prov ided that y ou also meet all of these conditions:

1. The work must carry prominent notices stating that y ou modif ied it, and giv ing a relev ant date.

2. The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modif ies the requirement in section 4 to “keep intact all notices”.

3. You must license the entire work, as a whole, under this License to any one who comes into possession of a copy . This License will theref ore apply , along with any applicable section 7 additional terms, to the whole of the work, and all its parts, regardless of how they are packaged. This License giv es no permission to license the work in any other way , but it does not inv alidate such permission if y ou hav e separately receiv ed it.

4. If the work has interactiv e user interf aces, each must display Appropriate Legal Notices; howev er, if the Program has interactiv e interf aces that do not display Appropriate Legal Notices, y our work need not make them do so.

A compilation of a cov ered work with other separate and independent works, which are not by their nature extensions of the cov ered work, and which are not combined with it such as to f orm a larger program, in or on a v olume of a storage or distribution medium, is called an “aggregate” if the compilation and its resulting copy right are not used to limit the access or legal rights of the compilation’s users bey ond what the indiv idual works permit. Inclusion of a cov ered work in an aggregate does not cause this License to apply to the other parts of the aggregate.

7. Conv ey ing Non-Source Forms. You may conv ey a cov ered work in object code f orm under the terms of sections 4 and 5, prov ided that y ou also conv ey the machine-readable Corresponding Source under the terms of this License, in one of these way s:

1. Conv ey the object code in, or embodied in, a phy sical product (including a phy sical distribution medium), accompanied by the Corresponding Source f ixed on a durable phy sical medium customarily used f or sof tware interchange.

2. Conv ey the object code in, or embodied in, a phy sical product (including a phy sical distribution medium), accompanied by a written of f er, v alid f or at least three y ears and v alid f or as long as y ou of f er spare parts or customer support f or that product model, to giv e any one who possesses the object code either (1) a copy of the Corresponding Source f or all the sof tware in the product that is cov ered by this License, on a durable phy sical medium customarily used f or sof tware interchange, f or a price no more than y our reasonable cost of phy sically perf orming this conv ey ing of source, or (2) access to copy the Corresponding Source f rom a network serv er at no charge.

3. Conv ey indiv idual copies of the object code with a copy of the written of f er to prov ide the

Corresponding Source. This alternativ e is allowed only occasionally and noncommercially , and only if y ou receiv ed the object code with such an of f er, in accord with subsection 6b.

4. Conv ey the object code by of f ering access f rom a designated place (gratis or f or a charge), and of f er equiv alent access to the Corresponding Source in the same way through the same place at no f urther charge. You need not require recipients to copy the Corresponding Source along with the object code. If the place to copy the object code is a network serv er, the Corresponding Source may be on a dif f erent serv er (operated by y ou or a third party ) that supports equiv alent copy ing f acilities, prov ided y ou maintain clear directions next to the object code say ing where to f ind the Corresponding Source. Regardless of what serv er hosts the Corresponding Source, y ou remain obligated to ensure that it is av ailable f or as long as needed to satisf y these requirements.

5. Conv ey the object code using peer-to-peer transmission, prov ided y ou inf orm other peers where the object code and Corresponding Source of the work are being of f ered to the general public at no charge under subsection 6d.

A separable portion of the object code, whose source code is excluded f rom the Corresponding Source as a Sy stem Library , need not be included in conv ey ing the object code work.

A “User Product” is either (1) a “consumer product”, which means any tangible personal property which is normally used f or personal, f amily , or household purposes, or (2) any thing designed or sold f or incorporation into a dwelling. In determining whether a product is a consumer product, doubtf ul cases shall be resolv ed in f av or of cov erage. For a particular product receiv ed by a particular user, “normally used” ref ers to a ty pical or common use of that class of product, regardless of the status of the particular user or of the way in which the particular user actually uses, or expects or is expected to use, the product. A product is a consumer product regardless of whether the product has substantial commercial, industrial or non-consumer uses, unless such uses represent the only signif icant mode of use of the product. “Installation Inf ormation” f or a User Product means any methods, procedures, authorization key s, or other inf ormation required to install and execute modif ied v ersions of a cov ered work in that User Product f rom a modif ied v ersion of its Corresponding Source. The inf ormation must suf f ice to ensure that the continued f unctioning of the modif ied object code is in no case prev ented or interf ered with solely because modif ication has been made.

If y ou conv ey an object code work under this section in, or with, or specif ically f or use in, a User Product, and the conv ey ing occurs as part of a transaction in which the right of possession and use of the User Product is transf erred to the recipient in perpetuity or f or a f ixed term (regardless of how the transaction is characterized), the Corresponding Source conv ey ed under this section must be accompanied by the Installation Inf ormation. But this requirement does not apply if neither y ou nor any third party retains the ability to install modif ied object code on the User Product (f or example, the work has been installed in ROM).

The requirement to prov ide Installation Inf ormation does not include a requirement to continue to prov ide support serv ice, warranty , or updates f or a work that has been modif ied or installed by the recipient, or f or the User Product in which it has been modif ied or installed.

Access to a network may be denied when the modif ication itself materially and adv ersely af f ects the operation of the network or v iolates the rules and protocols f or communication across the network.

Corresponding Source conv ey ed, and Installation Inf ormation prov ided, in accord with this section must be in a f ormat that is publicly documented (and with an implementation av ailable to the public in source code f orm), and must require no special password or key f or unpacking, reading or copy ing.

8. Additional Terms. "Additional permissions" are terms that supplement the terms of this License by making exceptions f rom one or more of its conditions. Additional permissions that are applicable to the entire Program shall be treated as though they were included in this License, to the extent that they are v alid under applicable law. If additional permissions apply only to part of the Program, that part may be used separately under those permissions, but the entire Program remains gov erned by this License without regard to the additional permissions. When y ou conv ey a copy of a cov ered work, y ou may at y our option remov e any additional permissions f rom that copy , or f rom any part of it. (Additional permissions may be written to require their own remov al in certain cases when y ou modif y the work.) You may place additional permissions on material, added by y ou to a cov ered work, f or which y ou hav e or can giv e appropriate copy right permission. Notwithstanding any other prov ision of this License, f or material y ou add to a cov ered work, y ou may (if authorized by the copy right holders of that material) supplement the terms of this License with terms:

1. Disclaiming warranty or limiting liability dif f erently f rom the terms of sections 15 and 16 of this License; or

2. Requiring preserv ation of specif ied reasonable legal notices or author attributions in that material or in the Appropriate Legal Notices display ed by works containing it; or

3. Prohibiting misrepresentation of the origin of that material, or requiring that modif ied v ersions of such material be marked in reasonable way s as dif f erent f rom the original v ersion; or

4. Limiting the use f or publicity purposes of names of licensors or authors of the material; or

5. Declining to grant rights under trademark law f or use of some trade names, trademarks, or serv ice marks; or

6. Requiring indemnif ication of licensors and authors of that material by any one who conv ey s the material (or modif ied v ersions of it) with contractual assumptions of liability to the recipient, f or any liability that these contractual assumptions directly impose on those licensors and authors.

All other non-permissiv e additional terms are considered “f urther restrictions” within the meaning of section 10. If the Program as y ou receiv ed it, or any part of it, contains a notice stating that it is gov erned by this License along with a term that is a f urther restriction, y ou may remov e that term. If a license document contains a f urther restriction but permits relicensing or conv ey ing under this License, y ou may add to a cov ered work material gov erned by the terms of that license document, prov ided that the f urther restriction does not surv iv e such relicensing

or conv ey ing. If y ou add terms to a cov ered work in accord with this section, y ou must place, in the relev ant source f iles, a statement of the additional terms that apply to those f iles, or a notice indicating where to f ind the applicable terms. Additional terms, permissiv e or non-permissiv e, may be stated in the f orm of a separately written license, or stated as exceptions; the abov e requirements apply either way .

9. Termination. You may not propagate or modif y a cov ered work except as expressly prov ided under this License. Any attempt otherwise to propagate or modif y it is v oid, and will automatically terminate y our rights under this License (including any patent licenses granted under the third paragraph of section 11). Howev er, if y ou cease all v iolation of this License, then y our license f rom a particular copy right holder is reinstated (a) prov isionally , unless and until the copy right holder explicitly and f inally terminates y our license, and (b) permanently , if the copy right holder f ails to notif y y ou of the v iolation by some reasonable means prior to 60 day s af ter the cessation. Moreov er, y our license f rom a particular copy right holder is reinstated permanently if the copy right holder notif ies y ou of the v iolation by some reasonable means, this is the f irst time y ou hav e receiv ed notice of v iolation of this License (f or any work) f rom that copy right holder, and y ou cure the v iolation prior to 30 day s af ter y our receipt of the notice. Termination of y our rights under this section does not terminate the licenses of parties who hav e receiv ed copies or rights f rom y ou under this License. If y our rights hav e been terminated and not permanently reinstated, y ou do not qualif y to receiv e new licenses f or the same material under section.

10.Acceptance Not Required f or Hav ing Copies. You are not required to accept this License in order to receiv e or run a copy of the Program. Ancillary propagation of a cov ered work occurring solely as a consequence of using peer-to-peer transmission to receiv e a copy likewise does not require acceptance. Howev er, nothing other than this License grants y ou permission to propagate or modif y any cov ered work. These actions inf ringe copy right if y ou do not accept this License. Theref ore, by modif y ing or propagating a cov ered work, y ou indicate y our acceptance of this License to do so.

11.Automatic Licensing of Downstream Recipients. Each time y ou conv ey a cov ered work, the recipient automatically receiv es a license f rom the original licensors, to run, modif y and propagate that work, subject to this License. You are not responsible f or enf orcing compliance by third parties with this License. An “entity transaction” is a transaction transf erring control of an organization, or substantially all assets of one, or subdiv iding an organization, or merging organizations. If propagation of a cov ered work results f rom an entity transaction, each party to that transaction who receiv es a copy of the work also receiv es whatev er licenses to the work the party ’s predecessor in interest had or could giv e under the prev ious paragraph, plus a right to possession of the Corresponding Source of the work f rom the predecessor in interest, if the predecessor has it or can get it with reasonable ef f orts. You may not impose any f urther restrictions on the exercise of the rights granted or af f irmed under this License. For example, y ou may not impose a license f ee, roy alty , or other charge f or exercise of rights granted under this License, and y ou may not initiate litigation (including a cross-claim or counterclaim in a lawsuit) alleging that any patent claim is inf ringed by making, using, selling, of f ering f or sale, or importing the Program or any portion of it.

12.Patents. A “contributor” is a copy right holder who authorizes use under this License of the Program or a work on which the Program is based. The work thus licensed is called the contributor’s “contributor v ersion”.

A contributor’s “essential patent claims” are all patent claims owned or controlled by the contributor, whether already acquired or hereaf ter acquired, that would be inf ringed by some manner, permitted by this License, of making, using, or selling its contributor v ersion, but do not include claims that would be inf ringed only as a consequence of f urther modif ication of the contributor v ersion. For purposes of this def inition, “control” includes the right to grant patent sublicenses in a manner consistent with the requirements of this License.

Each contributor grants y ou a non-exclusiv e, worldwide, roy alty -f ree patent license under the contributor’s essential patent claims, to make, use, sell, of f er f or sale, import and otherwise run, modif y and propagate the contents of its contributor v ersion. In the f ollowing three paragraphs, a “patent license” is any express agreement or commitment, howev er denominated, not to enf orce a patent (such as an express permission to practice a patent or cov enant not to sue f or patent inf ringement). To “grant” such a patent license to a party means to make such an agreement or commitment not to enf orce a patent against the party .

If y ou conv ey a cov ered work, knowingly rely ing on a patent license, and the Corresponding Source of the work is not av ailable f or any one to copy , f ree of charge and under the terms of this License, through a publicly av ailable network serv er or other readily accessible means, then y ou must either (1) cause the Corresponding Source to be so av ailable, or (2) arrange to depriv e y ourself of the benef it of the patent license f or this particular work, or (3) arrange, in a manner consistent with the requirements of this License, to extend the patent license to downstream recipients. “Knowingly rely ing” means y ou hav e actual knowledge that, but f or the patent license, y our conv ey ing the cov ered work in a country , or y our recipient’s use of the cov ered work in a country , would inf ringe one or more identif iable patents in that country that y ou hav e reason to believ e are v alid. If , pursuant to or in connection with a single transaction or arrangement, y ou conv ey , or propagate by procuring conv ey ance of , a cov ered work, and grant a patent license to some of the parties receiv ing the cov ered work authorizing them to use, propagate, modif y or conv ey a specif ic copy of the cov ered work, then the patent license y ou grant is automatically extended to all recipients of the cov ered work and works based on it.

A patent license is “discriminatory ” if it does not include within the scope of its cov erage, prohibits the exercise of , or is conditioned on the non-exercise of one or more of the rights that are specif ically granted under this License. You may not conv ey a cov ered work if y ou are a party to an arrangement with a third party that is in the business of distributing sof tware, under which y ou make pay ment to the third party based on the extent of y our activ ity of conv ey ing the work, and under which the third party grants, to any of the parties who would receiv e the cov ered work f rom y ou, a discriminatory patent license (a) in connection with copies of the cov ered work conv ey ed by y ou (or copies made f rom those copies), or (b) primarily f or and in connection with specif ic products or compilations that contain the cov ered work, unless y ou entered into that arrangement, or that patent license was granted, prior to 28 March 2007.

Nothing in this License shall be construed as excluding or limiting any implied license or other def enses to inf ringement that may otherwise be av ailable to y ou under applicable patent law.

13.No Surrender of Others’ Freedom. If conditions are imposed on y ou (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse y ou f rom the conditions of this License. If y ou cannot conv ey a cov ered work so as to satisf y simultaneously y our obligations under this License and any other pertinent obligations, then as a consequence y ou may not conv ey it at all. For example, if y ou agree to terms that obligate y ou to collect a roy alty f or f urther conv ey ing f rom those to whom y ou conv ey the Program, the only way y ou could satisf y both those terms and this License would be to ref rain entirely f rom conv ey ing the Program.

14.Use with the GNU Af f ero Gnereral Public License. Notwithstanding any other prov ision of this License, y ou hav e permission to link or combine any cov ered work with a work licensed under v ersion 3 of the GNU Af f ero General Public License into a single combined work, and to conv ey the resulting work. The terms of this License will continue to apply to the part which is the cov ered work, but the special requirements of the GNU Af f ero General Public License, section 13, concerning interaction through a network will apply to the combination as such.

15.Rev ised Versions of this License. The Free Sof tware Foundation may publish rev ised and/or new v ersions of the GNU General Public License f rom time to time. Such new v ersions will be similar in spirit to the present v ersion, but may dif f er in detail to address new problems or concerns. Each v ersion is giv en a distinguishing v ersion number. If the Program specif ies that a certain numbered v ersion of the GNU General Public License “or any later v ersion” applies to it, y ou hav e the option of f ollowing the terms and conditions either of that numbered v ersion or of any later v ersion published by the Free Sof tware Foundation. If the Program does not specif y a v ersion number of the GNU General Public License, y ou may choose any v ersion ev er published by the Free Sof tware Foundation. If the Program specif ies that a proxy can decide which f uture v ersions of the GNU General Public License can be used, that proxy ’s public statement of acceptance of a v ersion permanently authorizes y ou to choose that v ersion f or the Program. Later license v ersions may giv e y ou additional or dif f erent permissions. Howev er, no additional obligations are imposed on any author or copy right holder as a result of y our choosing to f ollow a later v ersion.

16.Disclaimer of Warranty . THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM “AS IS” WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.

17.Limitation of Liability . IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR

CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.

18.Interpretation of Sections 15 and 16. If the disclaimer of warranty and limitation of liability prov ided abov e cannot be giv en local legal ef f ect according to their terms, rev iewing courts shall apply local law that most closely approximates an absolute waiv er of all civ il liability in connection with the Program, unless a warranty or assumption of liability accompanies a copy of the Program in return f or a f ee.

17.4.5 GCC Runtime Library Exception

gcc.gnu.org/onlinedocs/libstdc++/manual/license.html

GCC RUNTIME LIBRARY EXCEPTION

Version 3.1, 31 March 2009

Ev ery one is permitted to copy and distribute v erbatim copies of this license document, but changing it is not allowed.

This GCC Runtime Library Exception ("Exception") is an additional permission under section 7 of the GNU General Public License, v ersion 3 ("GPLv 3"). It applies to a giv en f ile (the "Runtime Library ") that bears a notice placed by the copy right holder of the f ile stating that the f ile is gov erned by GPLv 3 along with this Exception.

When y ou use GCC to compile a program, GCC may combine portions of certain GCC header f iles and runtime libraries with the compiled program. The purpose of this Exception is to allow compilation of non-GPL (including proprietary ) programs to use, in this way , the header f iles and runtime libraries cov ered by this Exception.

1. Def initions. A f ile is an "Independent Module" if it either requires the Runtime Library f or execution af ter a Compilation Process, or makes use of an interf ace prov ided by the Runtime Library , but is not otherwise based on the Runtime Library . "GCC" means a v ersion of the GNU Compiler Collection, with or without modif ications, gov erned by v ersion 3 (or a specif ied later v ersion) of the GNU General Public License (GPL) with the option of using any subsequent v ersions published by the FSF. "GPL-compatible Sof tware" is sof tware whose conditions of propagation, modif ication and use

would permit combination with GCC in accord with the license of GCC. "Target Code" ref ers to output f rom any compiler f or a real or v irtual target processor architecture, in executable f orm or suitable f or input to an assembler, loader, linker and/or execution phase. Notwithstanding that, Target Code does not include data in any f ormat that is used as a compiler intermediate representation, or used f or producing a compiler intermediate representation. The "Compilation Process" transf orms code entirely represented in non- intermediate languages designed f or human-written code, and/or in Jav a Virtual Machine by te code, into Target Code. Thus, f or example, use of source code generators and preprocessors need not be considered part of the Compilation Process, since the Compilation Process can be understood as starting with the output of the generators or preprocessors. A Compilation Process is "Eligible" if it is done using GCC, alone or with other GPL-compatible sof tware, or if it is done without using any work based on GCC. For example, using non-GPL-compatible Sof tware to optimize any GCC intermediate representations would not qualif y as an Eligible Compilation Process.

2. Grant of Additional Permission. You hav e permission to propagate a work of Target Code f ormed by combining the Runtime Library with Independent Modules, ev en if such propagation would otherwise v iolate the terms of GPLv 3, prov ided that all Target Code was generated by Eligible Compilation Processes. You may then conv ey such a combination under terms of y our choice, consistent with the licensing of the Independent Modules.

3. No Weakening of GCC Copy lef t. No Weakening of GCC Copy lef t. The av ailability of this Exception does not imply any general presumption that third-party sof tware is unaf f ected by the copy lef t requirements of the license of GCC.

Hopef ully that text is self -explanatory . If it isn't, y ou need to speak to y our lawy er, or the Free Sof tware Foundation.

This limitation of liability shall not apply to liability f or death or personal injury resulting f rom such party ’s negligence to the extent applicable law prohibits such limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion and limitation may not apply to You.

8. Litigation

Any litigation relating to this License may be brought only in the courts of a jurisdiction where the def endant maintains its principal place of business and such litigation shall be gov erned by laws of that jurisdiction, without ref erence to its conf lict-of -law prov isions.

The Software is provided with and uses libraries from the FFmpeg project under the LGPLv2.1, GNU Lesser General Public License (LGPL) version 2.1 or later (the “FFmpeg Libraries”), which are not owned by SMI. The FFmpeg code owners’ contact information and the LGPLv2.1 licensing terms and conditions can be found at http://ffmpeg.org

If you do not agree with these provisions, do not download, install or use the Licensed Materials. If you have already paid for the Licensed Materials, you may return them for a full refund to: SensoMotoric Instruments, Warthestraße 21, 14513 Teltow, Germany. If the Licensed Materials were installed on Designated Equipment, you may also return such Designated Equipment for a full refund.

1. License. Subject to the terms of this Agreement, SMI hereby grants and Licensee accepts a non-transferable, non-exclusive, non-assignable license without the right to sublicense to use the Licensed Materials only (i) for Licensee’s business operations, (ii) on the Designated Equipment, if any, or on a back-up equipment while the Designated Equipment is inoperable, and (iii) in accordance with the Documentation.

Licensee may make one copy of the Software in machine readable form for backup purposes only; every notice on the original will be replicated on the copy. Installation of the Software, if any, is Licensee’s sole responsibility.

2. Rights in Licensed Materials. Title to and ownership in the Licensed Materials and all proprietary rights with respect to the Licensed Materials and all copies and portions thereof, remain exclusively with SMI. The Agreement does not constitute a sale of the Licensed Materials or any portion or copy of it. Title to and ownership in Licensee’s application software that makes calls to but does not contain all or any portion of the Software remains with Licensee, but such application software may not be licensed or otherwise transferred to third parties without SMI’s prior written consent.

3. Confidentiality. Licensed Materials are proprietary to SMI and constitute SMI trade secrets. Licensee shall maintain Licensed Materials in confidence and prevent their disclosure using at least the same degree of care it uses for its own trade secrets, but in no event less than a reasonable degree of care. Licensee shall not disclose Licensed Materials or any part thereof to anyone for any purpose, other than to its employees and sub-contractors for the purpose of exercising the rights expressly granted under this Agreement, provided they have in writing agreed to confidentiality obligations at least equivalent to the obligations stated herein.

4. No Reverse Engineering. License shall not, and shall not allow any third party to, decompile, disassemble or otherwise reverse engineer or by any means whatsoever attempt to reconstruct or discover any source code or underlying ideas, algorithms, file formats or programming or interoperability interfaces of the Software or of any files contained or generated using the Software. The obligations under this Section shall survive any termination of the Agreement. Licensee may apply to SMI at the address above for further information on the interface between the Software and other applications; SMI will on reasonable terms and conditions provide such information as the Licensee may reasonably require to enable the Software to interoperate with its applications. These restrictions do not apply to the FFmpeg Libraries.

5. Warranty.

a) If Licensed Materials show a defect during the limitation period specified in Sec. 5 d), which already existed at the time of transfer of risk, SMI will provide Licensee with a corrected version of such defective Licensed Material (“Repeat Performance”).

b) Licensed Materials are defective, if they do not conform to the written agreement between SMI and Licensee, if any, or to SMI’s specification.

c) Licensee’s claims for defects are excluded:

for insignificant divergences from the agreement or specification;

for damages caused after the transfer of risk by external influences such as fire, water, currency surge, etc.; improper installation, operation, use or maintenance; use in fields of application and environmental conditions other than those expressly specified by SMI; and use in combination with other products not approved by SMI for this purpose, excessive stress or normal wear and tear;

for defects of the Software, which cannot be reproduced;

for Licensee’s or a third party’s modifications of Licensed Materials and results therefrom;

in as far as Licensee has not notified SMI of apparent defects within 5 business days of delivery and of hidden defects within 5 business days of discovery.

d) The limitation period for warranty claims is 12 months. This does not apply in cases of fraud, intent, gross negligence and personal injury. Repeat performance does not restart the limitation period.

e) Licensee has to always first provide SMI the opportunity for Repeat Performance within a reasonable period of time. Repeat Performance does not constitute acceptance of a legal obligation.

f) If the Repeat Performance fails even within an additional period of time of reasonable length to be granted by Licensee, Licensee shall, notwithstanding its claims under Section 6, if any, be entitled to rescind the contract or to claim a price reduction.

g) If the analysis of an alleged defect shows that it is not covered by the above warranty, SMI may charge for the failure analysis and correction of the defect, if any, at SMI’s then applicable rates.

6. Liability Limitations.

a) SMI is only liable for damages caused by slight negligence if such are due to a material breach of duty, which endangers the achievement of the objective of the Agreement, or the failure to comply with duties, the very discharge of which is an essential prerequisite for the proper performance of the Agreement.

b) In cases of Section 6 a), the liability is limited to the damage, which is typical for contracts like this Agreement and which could have been foreseen.

c) SMI’s liability is also limited to the damage, which is typical for contracts like this Agreement and which could have been foreseen for damages caused by the gross negligence of an agent or an employee of SMI, who is not an officer or executive of SMI.

d) In cases of Sections 6 a) and c), SMI’s liability is limited to a maximum amount of EURO 500.000, respectively EURO 100.000 for financial losses.

e) Licensee’s claims for damages caused by slight negligence or caused by the gross negligence of an agent or an employee of SMI, who is not an officer or executive of SMI, which are not based on defects and thus not subject to time-barring in accordance with Sec. 5 d) are time- barred at the latest 2 years from the point in time Licensee became aware of the damage and regardless of Licensee’s awareness at the latest 3 years after the damaging event.

f) With the exception of liability under the Product Liability Law, for defects after having given a guarantee, for fraudulently concealed defects and for personal injury, the above limitations of liability shall apply to all claims, irrespective of their legal basis, in particular to all claims based on breach of contract or tort.

g) The above limitations of liability also apply in case of Licensee’s claims for damages against SMI’s employees or agents.

7. SMI Indemnity. SMI will defend or settle any action brought against Licensee to the extent based on a claim that Licensed Materials, used within the scope of the license granted in this Agreement, infringe any copyright valid in the European Union or the European Economic Area and will pay the cost of any final settlement or judgment attributable to such claim, provided (i) Licensee has given prompt notice to SMI of such claim, (ii) Licensee has not recognized an infringement of the third party’s copyright, and (iii) the entire defense and the settlement negotiations are reserved for SMI with Licensee’s full cooperation and support. If Licensee discontinues the use of Licensed Materials for damage reduction or other important reasons, Licensee is obligated to point out to the third party that the discontinuation of use does not constitute an acknowledgment of a copyright infringement. If SMI believes Licensed Materials are likely to be the subject of an infringement claim, it may elect to replace or modify such Software or Documentation to make it non-infringing or terminate the Agreement on written notice to Licensee. SMI shall have no obligation to defend (or any other liability) to the extent any claim involves a Software release other than the current, unaltered release, if such would have avoided infringement, or use of the Software in combination with non-SMI programs or data, unless the infringement would also incur without such combination. The foregoing states the entire obligation and liability of SMI with respect to any infringement by Licensed Materials of any intellectual property rights or other proprietary rights of Licensee or a third party without prejudice to any claims for damages in accordance with Section 6.

8. Licensee Indemnity. Licensee will defend and indemnify SMI, and hold it harmless from all costs, including attorney’s fees, arising from any claim that may be made against SMI by any third party as a result of Licensee’s use of Licensed Materials, excluding claims for which SMI is obligated to

defend or indemnify Licensee under Section 7.

9. Export Restriction. Licensee will not remove or export from Germany or from the country Licensed Materials were originally shipped to by SMI or re-export from anywhere any part of the Licensed Materials or any direct product of the Software except in compliance with all applicable export laws and regulations, including without limitation, those of the U.S. Department of Commerce.

10.Non-Waiver; Severability; Non-Assignment. The delay or failure of either party to exercise any right provided in this Agreement shall not be deemed a waiver. If any provision of this Agreement is held invalid, all others shall remain in force. Licensee may not, in whole or in part, assign or otherwise transfer this Agreement or any of its rights or obligations hereunder.

11.Termination. This Agreement may be terminated without any fee reduction (i) by Licensee without cause on 30 days notice; (ii) by SMI, in addition to other remedies, if Licensee fails to cure any breach of its obligations hereunder within 30 days of notice thereof; (iii) on notice by either party if the other party ceases to do business in the normal course, becomes insolvent, or becomes subject to any bankruptcy, insolvency, or equivalent proceedings. Upon termination by either party for any reason, Licensee shall at SMI’s instructions immediately destroy or return the Licensed Materials and all copies thereof to SMI and delete the Software and all copies thereof from the Designated Equipment.

12.Entire Agreement; Written Form Requirement. There are no separate oral agreements; any supplementary agreements or modifications hereto must be made in writing. This also applies to any waiver of this requirement of written form.

13.Notices. All notices under the Agreement must be in writing and shall be delivered by hand or by overnight courier to the addresses of the parties set forth above.

14.Applicable Law and Jurisdiction. German law applies with the exception of its conflict of laws rules. The application of the United Nations

Convention on Contracts for the International Sale of Goods (CISG) is expressly excluded The courts of Berlin, Germany, shall have exclusive jurisdiction for any action brought under or in connection with this Agreement.
