In this workshop, we explore novel applications, services, tools, and systems that take advantage of the audio channel on mobile devices to feed users with a flow of information. We call for innovative ideas to introduce ambient context-aware, location-aware, and/or social audio as a more effective means of communicating information and providing experiences to mobile users.

We present ConnectBoard, a new system for remote collaboration where users experience natural interaction with one another, seemingly separated only by a vertical, transparent sheet of glass. It overcomes two key shortcomings of conventional video communication systems: the inability to seamlessly capture natural user interactions, like using hands to point and gesture at parts of shared documents, and the inability of users to look into the camera lens without taking their eyes off the display. We solve these problems by placing the camera behind the screen, where the remote user is virtually located. The camera sees through the display to capture images of the user. As a result, our setup captures natural, frontal views of users as they point and gesture at shared media displayed on the screen between them. Users also never have to take their eyes off their screens to look into the camera lens. Our novel optical solution based on wavelength multiplexing can be easily built with off-the-shelf components and does not require custom electronics for projector-camera synchronization.

Mobile video is now an everyday possibility with a wide array of commercially available devices, services and content. These technologies promise to transform the way that people can consume video media in their lives beyond the familiar behaviours associated with fixed TV and video technologies. Building upon earlier studies of mobile video, this paper reports on a study using diary techniques and ethnographic interviews to better understand how people are using commercially available mobile video technologies in their everyday lives. Drawing on reported episodes of mobile video behaviour, the study identifies the social motivations and values underpinning these behaviours that help characterise mobile video consumption beyond the simplistic notion of viewing TV to kill time wherever you may be. Implications for adoption and design of mobile video technologies and services are discussed.
