Literature Review- UniCast, OutCast & GroupCast
UniCast, OutCast & GroupCast (McCarthy, Costa et al. 2001)The authors discuss the deployment of peripheral displays in three workplace contexts, within an office (unicast), outside an office (outcast), and in a common area (groupcast). Of these contexts, the groupcast context is of the most direct relevance to building public displays (It should be noted that the authors describe a modular system of data sources in unicast, where users can customize their display using a series of modules, each with it’s own preferences – which is later used to power the content displayed on the Groupcast system). The Groupcast system uses an existing employee tracking framework to display the location of employees, and displays content on the public display based on who is near the display, and the individual preferences of users who are near the display. For example, if two users are near the display, the display will display content specified by one of the two users in their personal preferences with the goal of facilitating communication between the individuals. This paper lacks a worthwhile evaluation, as neither GroupCast nor OutCast were evaluated, and most of the evaluation of unicast was regulated to what modules different users were interested in. However, this paper is one of the early papers on using user preferences to drive public displays when users are near them, so it is worth noting this idea if nothing else.
