Manipulation of Video Eye Gaze and Head Orientation for Video Teleconferencing
C. Lawrence Zitnick, Jim Gemmell, Kentaro Toyama · 1999
Many desktop videoconferencing systems are ineffective due to deficiencies in gaze awareness and sense of spatial relationship. Gaze awareness and spatial relationships can be restored by software if heads and eyes can be tracked in video, and then graphically manipulated. We discuss graphics algorithms for manipulating eye gaze and head orientation. Our system takes video input annotated with head and eye information and outputs an adjusted video with appropriate gaze and head orientation. Initial results demonstrate the viability and usefulness of such a system. 1 Introduction For over 50 years we have been hearing that video conferencing is about to become ubiquitous. The experience, however, is that most people question its usefulness [Chap72, Gale89]---we could easily write a primer on "How to fail at video-conferencing". It would include tips like: 1. Have long audio latencies and poor audio quality. 2. Make sure no-one else has compatible equipment. 3. Make it much harder to ...
