Title:
METHOD AND SYSTEM FOR INDICATING CHANGE OF SPEAKER IN A VIDEOCONFERENCE APPLICATION
Document Type and Number:
WIPO Patent Application WO2001080562
Kind Code:
A3
Abstract:
A videoconferencing application suitable for large conferences with many terminals where displayed speakers are changed dynamically based on some schema employs animation effects to indicate the change. When a new speaker replaces an old, the new speaker's image is gradually transitioned into the place of the old speaker's by an animation that provides a clear cue and a visual metaphor for the event. A preferred embodiment translates the new image in and the old one out as if the new one were pushing the old image out of its place. Various other animations are also described which provide a similar result.
