CoStream@Home: connected live event experiences

Live events can be mainly experienced in two different ways: spectators are either present in-situ, i.e. in the stadium, or they witness the event remotely, e.g. at home or in a pub. Although both experiences concern the same event, they are fundamentally different. In addition, communication between these two 'spectating realms' is rather cumbersome, preventing spectators to co-experience events over a distance. In this paper, we contribute a system aiming at bridging this gap by establishing a two-way communication channel between the two realms through sharing user-generated mobile live video. We describe implementation details, depict salient interaction techniques and conclude with promising research directions.
