    Gradual Engagement between Digital Devices as a Function of Proximity: From Awareness to Progressive Reveal to Information Transfer
    (2012-04-20T17:29:40Z) Marquardt, Nicolai; Ballendat, Till; Boring, Sebastian; Greenberg, Saul; Hinckley, Ken
    Connecting and information transfer between the increasing number of personal and shared digital devices in our environment – phones, tablets, and large surfaces – is tedious. One has to know which devices can communicate, what information they contain, and how information can be exchanged. Inspired by Proxemic Interactions, we introduce novel interaction techniques that allow people to naturally connect to and perform cross-device operations. Our techniques are based on the notion of gradual engagement between a person’s handheld device and the other devices surrounding them as a function of finegrained measures of proximity. They all provide awareness of device presence and connectivity, progressive reveal of available digital content, and interaction methods for transferring digital content between devices from a distance and from close proximity. They also illustrate how gradual engagement may differ when the other device seen is personal (such as a handheld) vs. semi-public (such as a large display). We illustrate our techniques within two applications that enable gradual engagement leading up to information exchange between digital devices.

    Proxemic Interaction: The Video
    (2010-07-07T21:31:31Z) Ballendat, Till; Marquardt, Nicolai; Greenberg, Saul
    This video illustrates how we used proxemic information to regulate interactions of people, digital devices, and non-digital artefacts with an interactive vertical display surface. It shows how proxemics can regulate implicit and explicit interaction techniques, as well as how proxemic interactions can be triggered by continuous movement, or by movement in and out of discrete proxemic regions. Our example application is an interactive media player that implicitly reacts to the approach and orientation of people and their personal devices, and that tailors explicit interaction methods to fit.

    A Proximity and Orientation Aware Video Playback Application
    (2010) Ballendat, Till; Marquardt, Nicolai; Greenberg, Saul
    This application, built atop the proximity toolkit, controls video playback on a large screen and reacts accordingly to a number of implicit actions. It shows different views on video data depending on the user’s presence and proximity. It allows one to select and browse by touching or by pointing from a distance with a mobile phone.Sitting down and looking at the screen automatically enables video playback and other people that enter the room will be provided with additional information about the playing video. The system can recognize user actions, like making a call or looking away and pause the playback. For more information, http://grouplab.cpsc.ucalgary.ca/cookbook/index.php/Demos/ProximityVideo
