Gaze awareness for video-conferencing: a software approach

S. Seitz, T. Kang, C.L. Zitnick, K. Toyama, J. Gemmell
2000 IEEE Multimedia  
Here, we superimposed the eyes and nose onto the face-at first glance, the head appears to be turned to the right.  ...  While waiting for computer vision to come up to speed, we might work with infrared-based vision systems so that we can push ahead with research on our virtual 3D conferencing environment.  ...  If a head model has an incorrect mouth curvature, for example, the subject's mouth might look either happy or sad when the head model rotates up and down.  ...
