Virtual identities in interactive broadcasting
The story was the bushman's most sacred posession. These people knew what we do not; that without a story you have not got a nation, or culture or civilisation. Without a story of your own to live, you haven't got a life of your own. . Since our childhood we are exposed to stories in a variety of forms and they reflect the richness of our civilisation. Movies, cartoons, television series, advertisements, multimedia and computer games are all built around narrative structures. However, the potential of interactive narratives has not yet been fully explored by interactive television in comparison to its many uses in virtual environments and computer games. In a previous paper we proposed the virtual identity approach for authoring interactive experiences in Virtual Environments. With this approach the user is experiencing virtual environments through the eyes of a virtual identity, resulting in different interactive experiences within the same environment. We used the approach and authoring tool to author the Cato Manor interactive experience. This paper focuses on the transition mechanism and the ways it can be used to enhance interactive experiences. It also proposes ways of using the approach with today's technology of interactive broadcasting.
