  • Using Pebble
    Using Pebble Pebble has four buttons. The left button is called the 'back' button, which is used for returning to the previous screen or entering your watchface app from the main menu. On the right side, the top and bottom ('up' and 'down') buttons generally are used for scrolling through lists. The center button is used to 'select' an item in a list or start an app on Pebble. It can also be used to get to the main menu from a watchface. Though most navigation is done with a quick press of a button, some apps incorporate longer presses to expose more options, as seen with he music volume control below. Music Select the Music controller from main menu to control music playing on your smartphone. Currently, Pebble can control the default music app and Google music on Android, and Pandora, Spotify and any other music app that implements default music controls on iOS. Once inside the app, the select button will play or pause your music. And if you press and hold the select button for 1­2 seconds, the ability to skip tracks using the up and down buttons will change to volume control. Notifications The Notifications option from the main menu is a quick way to review your notification history. You will be able to scroll through and pull up any recent notices that you want to see again, or perhaps missed the first time around. There are two ways to clear your notification history, if you need to. First, the archive of messages is automatically reset whenever Pebble is; i.e.

For detailed segmentation, please see pages 59-68. Each category is forecast in three scenarios: core, low and high, as the market is still young and has an elevated level of uncertainty. – The core scenario describes the most likely outcome across all categories, given our current understanding. – A change in one category can trigger changes in other categories. The summary presents the core scenario for all four categories. – Low and high scenarios for the different categories cannot be added, as significant cannibalization could happen between segments — a high scenario for one is likely to mean a shift toward the low scenario of another. We have developed a split by device form in the core scenario. – This is a top-down split and subject to a significant uncertainty owing to the very early days of the market; one hugely successful product can greatly change the outlook. The sell-in value forecast is developed at a constant exchange rate of pounds to dollars from April 2016 onward.

  • ETAO Keyboard: Text Input Technique on Smartwatches
    Available online at www.sciencedirect.com ScienceDirect Procedia Computer Science 84 ( 2016 ) 137 – 141 7th International conference on Intelligent Human Computer Interaction, IHCI 2015 ETAO Keyboard: Text Input Technique on Smartwatches Rajkumar Darbara,∗, Punyashlok Dasha, Debasis Samantaa aSchool of Information Technology, IIT Kharagpur, West Bengal, India Abstract In the present day context of wearable computing, smartwatches augment our mobile experience even further by providing in- formation at our wrists. What they fail to do is to provide a comprehensive text entry solution for interacting with the various app notifications they display. In this paper we present ETAO keyboard, a full-fledged keyboard for smartwatches, where a user can input the most frequent English alphabets with a single tap. Other keys which include numbers and symbols are entered by a double tap. We conducted a user study that involved sitting and walking scenarios for our experiments and after a very short training session, we achieved an average words per minute (WPM) of 12.46 and 9.36 respectively. We expect that our proposed keyboard will be a viable option for text entry on smartwatches. ©c 20162015 TheThe Authors. Authors. Published Published by byElsevier Elsevier B.V. B.V.

  • Evaluating the Placement of Arm-Worn Devices for Recognizing Variations of Dynamic Hand Gestures
    Journal of Mobile Multimedia, Vol. 12, No. 3&4 (2017) 225{242 c Rinton Press EVALUATING THE PLACEMENT OF ARM-WORN DEVICES FOR RECOGNIZING VARIATIONS OF DYNAMIC HAND GESTURES KATHRIN KEFER CLEMENS HOLZMANN RAINHARD DIETER FINDLING Department of Mobile Computing, University of Applied Sciences Upper Austria Softwarepark 11, Hagenberg, 4232, Austria fkathrin.keferg,fclemens.holzmanng,frainhard.fi[email protected] Dynamic hand gestures have become increasingly popular as touch-free input modality for interactive systems. There exists a variety of arm-worn devices for the recognition of hand gestures, which differ not only in their capabilities, but also in their positioning on users' arms. These differences in positioning might influence how well gestures are recognized, leading to different gesture recognition accuracies. In this paper, we investi- gate the effect of device placement on dynamic hand gesture recognition accuracy. We consider devices being strapped to the forearm on two positions: the wrist and below the elbow. These positions represent smart watches being worn on the wrist and devices with EMG sensors for the additional detection of static hand gestures (e.g spreading the fingers) being worn right below the elbow. Our hypothesis is that wrist-worn devices will have better recognition accuracy, caused by higher acceleration values of a bigger action radius of dynamic hand gestures. We conducted a comparative study using an LG G Watch and Thalmic Labs' Myo armband, for which we recorded a total of 12960 gesture samples of eight simple dynamic gestures in three different variants with eight participants. We evaluated a potential difference in gesture recognition accuracies us- ing different feature sets and classifiers.

X, NO. X, MONTH YEAR 1 Identification of Wearable Devices with Bluetooth Hidayet Aksu, A. Selcuk Uluagac, Senior Member, IEEE, and Elizabeth S. Bentley Abstract With wearable devices such as smartwatches on the rise in the consumer electronics market, securing these wearables is vital. However, the current security mechanisms only focus on validating the user not the device itself. Indeed, wearables can be (1) unauthorized wearable devices with correct credentials accessing valuable systems and networks, (2) passive insiders or outsider wearable devices, or (3) information-leaking wearables devices. Fingerprinting via machine learning can provide necessary cyber threat intelligence to address all these cyber attacks. In this work, we introduce a wearable fingerprinting technique focusing on Bluetooth classic protocol, which is a common protocol used by the wearables and other IoT devices. Specifically, we propose a non-intrusive wearable device identification framework which utilizes 20 different Machine Learning (ML) algorithms in the training phase of the classification process and selects the best performing algorithm for the testing phase.

  • Smartwatch Security Research TREND MICRO | 2015 Smartwatch Security Research
    Smartwatch Security Research TREND MICRO | 2015 Smartwatch Security Research Overview This report commissioned by Trend Micro in partnership with First Base Technologies reveals the security flaws of six popular smartwatches. The research involved stress testing these devices for physical protection, data connections and information stored to provide definitive results on which ones pose the biggest risk with regards to data loss and data theft. Summary of Findings • Physical device protection is poor, with only the Apple Watch having a lockout facility based on a timeout. The Apple Watch is also the only device which allowed a wipe of the device after a set number of failed login attempts. • All the smartwatches had local copies of data which could be accessed through the watch interface when taken out of range of the paired smartphone. If a watch were stolen, any data already synced to the watch would be accessible. The Apple Watch allowed access to more personal data than the Android or Pebble devices. • All of the smartwatches we tested were using Bluetooth encryption and TLS over WiFi (for WiFi enabled devices), so consideration has obviously been given to the security of data in transit. • Android phones can use ‘trusted’ Bluetooth devices (such as smartwatches) for authentication. This means that the smartphone will not lock if it is connected to a trusted smartwatch. Were the phone and watch stolen together, the thief would have full access to both devices. • Currently smartwatches do not allow the same level of interaction as a smartphone; however it is only a matter of time before they do.
