Publication: Semantic Telepointers for Groupware

Real time groupware systems often display telepointers (multiple cursors) of all participants in the shared visual workspace. Through the simple mechanism of telepointers, participants can communicate their location, movement, and probable focus of attention within the document, and can gesture over the shared view. Yet telepointers can be improved. First, they can be applied to groupware where people's view of the work surface differs—through viewport, object placement, or representation variation—by mapping telepointers to the underlying objects rather than to Cartesian coordinates. Second, telepointers can be overloaded with semantic information to provide participants a stronger sense of awareness of what is going on, with little consumption of screen real estate.
