According to folks from Celluon who came up with EvoMouse, it is the evolution of the computer mouse which allows you to emulate the mouse with gestures of your hand. The EvoMouse works on a similar principle as the Mouse less interface we wrote about last year, but its design is more polished and it looks like a small digital animal. Its two infrared sensors which form the eyes of the animal project an area in which your hands can function as if you really were using a mouse. The EvoMouse is the evolution of the computer mouse. Meet EvoMouse Pet, a dog-shaped device that turns any surface into a touchpad. Tracking your fingers, it lets you do anything a regular mouse can do, and then some. The EvoMouse works on nearly any flat surface and requires very little space. It tracks effortlessly to your comfortable and natural movements. With the EvoMouse, you can perform common mouse operations using only your fingers. You can control the cursor, click and select, double-click, right-click and drag with basic hand gestures. - 1 - 2. HISTORY 2.1 EARLY MOUSE The first functional mouse was actually demonstrated by Douglas Engelbart, a researcher from the Stanford Research Institute, back in 1963. The respective peripheral was far away from what we know today as “mice,” given the fact that it was manufactured from wood and featured two gear-wheels perpendicular to each other, the rotation of each single wheel translating into motion along one of the respective axis. It’s not exactly very clear where the name “mouse” originates, since, apparently, the name came from the fact that the device had a “tail” behind it, connecting it to a computer and a display and was the idea of Bill English, a colleague of Douglas Engelbart’s and the person who actually built the prototype device. Engelbart's product was not the first pointing device, though. In fact, it seems that the first such product, the trackball, was invented a lot earlier, namely at some point in 1953, by Tom Cranston, Fred Longstaff and Kenyon Taylor from the Royal Canadian Navy, as part of the secret military project DATAR. The name “trackball” comes from the fact that the respective device actually used a standard Canadian five-pin bowling ball. - 2 - Fig: 2.1 Earlier Mouse’s - 3 - 2.2 MECHANICAL MOUSE German company Telefunken published on their early ball mouse, called "Rollkugel" (German for "rolling ball"), on October 2, 1968. Telefunken's mouse was then sold commercially as optional equipment for their TR - 440 computers, which was first marketed in 1968. Telefunken did not apply for a patent on their device. Bill English, builder of Engelbart's original mouse, created a ball mouse in 1972 while working for Xerox PARC. It is also called as Roller ball mouse. The ball mouse replaced the external wheels with a single ball that could rotate in any direction. It came as part of the hardware package of the Xerox Alto computer. Perpendicular chopper wheels housed inside the mouse's body chopped beams of light on the way to light sensors, thus detecting in their turn the motion of the ball. This variant of the mouse resembled an inverted trackball and became the predominant form used with personal computers throughout the 1980s and 1990s. The Xerox PARC group also settled on the modern technique of using both hands to type on a full-size keyboard and grabbing the mouse when required. Fig.2.2 Mechanical mouse, shown with the top cover removed The ball mouse has two freely rotating rollers. They are located 90 degrees apart. One roller detects the forward – backward motion of the mouse and other the left – right motion. Opposite the two rollers is a third one (white, in the photo, at 45 degrees) that is spring - loaded to push the - 4 - ball against the other two rollers. Each roller is on the same shaft as an encoder wheel that has slotted edges; the slots interrupt infrared light beams to generate electrical pulses that represent wheel movement. Each wheel's disc, however, has a pair of light beams, located so thata given beam becomes interrupted, or again starts to pass light freely, when the other beam of the pair is about halfway between changes Simple logic circuits interpret the relative timing to indicate which direction the wheel is rotating. This incremental rotary encoder scheme is sometimes called quadrature encoding of the wheel rotation, as the two optical sensor produce signals that are in approximately quadrature phase. The mouse sends these signals to the computer system via the mouse cable, directly as logic signals in very old mice such as the Xerox mice, and via a data-formatting IC in modern mice. The driver software in the system converts the signals into motion of the mouse cursor along X and Y axes on the computer screen. The ball is mostly steel, with a precision spherical rubber surface. The weight of the ball, given an appropriate working surface under the mouse, provides a reliable grip so the mouse's movement is transmitted accurately. Fig.2.3 Mechanical Mouse Operating an optic-mechanical mouse: 1. Moving the mouse turns the ball. 2. X and Y rollers grip the ball and transfer movement - 5 - 3. Optical encoding disks include light holes. 4. Infrared LEDs shine through the disks. 5. Sensors gather light pulses to convert to X and Y vectors. 2.3 OPTICAL MOUSE Optical mice make use of one or more light-emitting diodes (LEDs) and an imaging array of photodiodes to detect movement relative to the underlying surface, rather than internal moving parts as does a mechanical mouse. A laser mouse is an optical mouse that uses coherent (laser) light. The earliest optical mice detected movement on pre-printed mouse pad surfaces, whereas the modern optical mouse works on most opaque surfaces; it is unable to detect movement on specular surfaces like glass. Laser diodes are also used for better resolution and precision. Battery powered, wireless optical mice flash the LED intermittently to save power, and only glow steadily when movement is detected. Fig.2.4 Optical Mouse Often called "air mice" since they do not require a surface to operate. It uses a tuning fork or other accelerometer to detect rotary movement for every axis supported. The most common models (manufactured by Logitech and Gyration) work using 2 degrees of rotational - 6 - freedom and are insensitive to spatial translation. The user requires only small wrist rotations to move the cursor. Usually cordless, they often have a switch to deactivate the movement circuitry between use, allowing the user freedom of movement without affecting the cursor position. A patent for an inertial mouse claims that such mice consume less power than optically based mice, and offer increased sensitivity, reduced weight and increased ease-of-use. In combination with a wireless keyboard an inertial mouse can offer alternative ergonomic arrangements which do not require a flat work surface, potentially alleviating some types of repetitive motion injuries related to workstation posture. Fig.2.5 Wireless optical mouse 2.4 LASER MOUSE The laser mouse uses an infrared laser diode instead of a LED to illuminate the surface beneath their sensor. As early as 1998, Sun Microsystems provided a laser mouse with their Sun SPARC station servers and workstations. However, laser mice did not enter the mainstream market until 2004, when Paul Machine at Logitech, in partnership with Agilent Technologies, introduced its MX 1000 laser mouse. This mouse uses a small infrared laser instead of a LED and has significantly increased the resolution of the image taken by the mouse. The laser enables around 20 times more surface tracking power to the surface features used for navigation compared to conventional optical mice. - 7 - Fig.2.6 Structure of Laser mouse Glass laser (or Glaser) mice have the same capability of a laser mouse but can also be used on top of mirror or transparent glass with few problems. In August 2009, Logitech introduced mice with two lasers, to track on glass and glossy surfaces better. These mice are considered as effective, sensitive and accurate devices as they support better tracking ability. With its user – friendly interface, this mouse is used by those users, who perform highly skilled jobs. One of the positive outcomes of this mouse is its energy efficient component that consumes lesser electricity when in use. Fig.2.7 Laser Mouse - 8 - 2.5 GYROSCOPIC MOUSE There are a number of computer pointing devices (in effect a mouse) on the market that have gyroscopes inside them allowing you to control the mouse cursor while the device is in the air! They are also wireless so are perfect for presentations when the speaker is moving around the room. The gyroscope inside tracks the movements of your hand and translates them to cursor movements. Fig.2.8 Gyroscopic mouse 2.6 3D MOUSE Also known as bats, flying mice, or wands, these devices generally function through ultrasound and provide at least three degrees of freedom. Probably the best known example would be 3D connexion / Logitech's Space Mouse from the early 1990s. In the late 1990s, Kantek introduced the 3D Ring Mouse. This wireless mouse was worn on a ring around a finger, which enabled the thumb to access three buttons. The mouse was tracked in three dimensions by a base station. Despite a certain appeal, it was finally discontinued because it did not provide sufficient resolution.

  • PROJECTION – VISION SYSTEMS: Towards a Human-Centric Taxonomy
    PROJECTION – VISION SYSTEMS: Towards a Human-Centric Taxonomy William Buxton Buxton Design www.billbuxton.com (Draft of May 25, 2004) ABSTRACT As their name suggests, “projection-vision systems” are systems that utilize a projector, generally as their display, coupled with some form of camera/vision system for input. Projection-vision systems are not new. However, recent technological developments, research into usage, and novel problems emerging from ubiquitous and portable computing have resulted in a growing recognition that they warrant special attention. Collectively, they represent an important, interesting and distinct class of user interface. The intent of this paper is to present an introduction to projection-vision systems from a human-centric perspective. We develop a number of dimensions according to which they can be characterized. In so doing, we discuss older systems that paved the way, as well as ones that are just emerging. Our discussion is oriented around issues of usage and user experience. Technology comes to the fore only in terms of its affordances in this regard. Our hope is to help foster a better understanding of these systems, as well as provide a foundation that can assist in making more informed decisions in terms of next steps. INTRODUCTION I have a confession to make. At 56 years of age, as much as I hate losing my hair, I hate losing my vision even more. I tell you this to explain why being able to access the web on my smart phone, PDA, or wrist watch provokes nothing more than a yawn from me. Why should I care? I can barely read the hands on my watch, and can’t remember the last time that I could read the date on it without my glasses.

Olaf Hellwich Berichter: Prof. Dr.-Ing. Marc Alexa Berichter: Prof. Dr. Andreas Kolb Tag der wissenschaftlichen Aussprache: 3. Mai 2012 Berlin 2012 D83 For my family. Abstract This thesis depicts approaches toward real-time depth sensing. While humans are very good at estimating distances and hence are able to smoothly control vehicles and their own movements, machines often lack the ability to sense their environ- ment in a manner comparable to humans. This discrepancy prevents the automa- tion of certain job steps. We assume that further enhancement of depth sensing technologies might change this fact. We examine to what extend time-of-flight (ToF) cameras are able to provide reliable depth images in real-time. We discuss current issues with existing real-time imaging methods and technologies in detail and present several approaches to enhance real-time depth imaging. We focus on ToF imaging and the utilization of ToF cameras based on the photonic mixer de- vice (PMD) principle. These cameras provide per pixel distance information in real-time. However, the measurement contains several error sources. We present approaches to indicate measurement errors and to determine the reliability of the data from these sensors. If the reliability is known, combining the data with other sensors will become possible. We describe such a combination of ToF and stereo cameras that enables new interactive applications in the field of computer graph- ics.

About 90% of the accidents occur due to human errors [2] [3] such as bad awareness, distraction, drowsiness, low training, fatigue etc. These human errors can be minimized by using advanced driver assistance system (ADAS) which actively monitors the driving environment and alerts a driver to the forthcoming danger, for example adaptive cruise control, blind spot detection, parking assistance, forward collision warning, lane departure warning, driver drowsiness detection, and traffic sign recognition etc. Unfortunately, these systems are provided only with modern luxury cars because they are very expensive due to numerous sensors employed. Therefore, camera-based ADAS are being seen as an alternative because a camera has much lower cost, higher availability, can be used for multiple applications and ability to integrate with other systems.

  • Realms As Entity Location Services
    Realms as Entity Location Services Realms as Entity Location Services A study of object orientation for the conceptual structure of the Internet Oliver F. J. Snowden for The Nuffield Foundation © 2004 Oliver Snowden Page: 1 of 93 Realms as Entity Location Services Summary New methods for organising the Internet need to be investigated and a new interface concept called Realms explored. It is hoped that Realms will enable access to a variety of devices not typically accessible over the Internet. This is needed since the Internet is rapidly expanding and huge numbers of devices are expected to be connected simultaneously (e.g. electricity meters, TVs, washing machines, individual lights, pipeline sensors). This introduces many difficulties, especially in referencing and organising such vast numbers of devices. Without efficient organisation current priority services, such as telephony, will be degraded. We have researched the following topics: • Current and potential Internet devices • Current and planned structure of the Internet • The Internet as an Object Oriented distributed database • The Realm concept with respect to the conceptual structure of the Internet. In addition we have • Ascertained any potential increase in productivity from Internet users using this concept • Conducted interviews with potential end-users and experts • Studied realm interfaces, and written critical analyses of • The Realm concept for the Internet structure • The Realm concept for widening access. The results of this study suggest that the scope of the devices connected to the Internet is likely to increase and that there are mechanisms which can facilitate the increased number of devices, both physically and virtually. Object Orientation (OO) was explained briefly to help highlight the benefits it can bring to users and computational systems.

This book treats a number of methodological questions essentially concerning the best usage of the 3D data made available by ToF cameras and Kinect TM , within a general approach valid independently of the specific depth measurement instrument employed. The practical exemplification of the results with actual data given in this book does not only confirm the effectiveness of the presented methods, but it also clarifies them and gives the reader a sense for their concrete possibilities. The reader will note that the ToF camera data presented in this book are obtained by the Mesa SR4000. This is because Mesa Imaging kindly made available their ToF camera and their guidance for its best usage in the experiments of this book.
