WorldTV A 3D globe-based interface for social video discovery

WorldTV is a proposed TV app for the discovery of user-generated video from around the world. We describe a two-screen solution (a TV app and accompanying mobile app to control what appears on the television screen) would let viewers browse and play geotagged videos plotted on a 3D model of the earth. The content would include video from viewers´ own social networks as well as user-generated news and event video filtered according to viewers´ interests, preferences, and social connections. In a world in which user-generated online video content is being uploaded and consumed at an exponential rate, the idea of using a globe-based navigation metaphor has powerful appeal. It is instantly approachable and easy to use, especially for people with global networks of friends, family, and colleagues living in other countries. We also argue that the widespread availability of geotagged video provides an additional impetus for using a geo-focused UI over more traditional browsing and discovery mechanisms.
