CoMedia: Mobile Group Media for Active Spectatorship

Previous attempts to support spectators at large-scale events have concentrated separately on real-time event information, awareness cues, or media-sharing applications. CoMedia combines a group media space with event information and integrates reusable awareness elements throughout. In two field trials, one at a rally and the other at a music festival, we found that CoMedia facilitated onsite reporting to offsite members, coordination of group action, keeping up to date with others, spectating remotely, and joking. In these activities, media, awareness cues, and event information were often used in concert, albeit assuming differing roles. We show that the integrated approach better supports continuous interweaving of use with the changing interests and occurrences in large-scale events.
