Use of steerable viewing window (SVW) to improve the visual sensation in face to face teleconferencing

We propose a method of using face direction information to make the local participant's video display of a video conferencing environment change according to his direction of view, in order to give him/her (the local participant) an improved visual sensation. We have named this method "steerable viewing window" (SVW). We also discuss an image processing method used to detect a person's face direction, without using special head mounted equipment. Further, we propose a method of reducing the data rate for transmission by coding the area around the gaze center with high resolution and the remaining with a lesser resolution. This method of saving bytes in video conferencing is named line of gaze centered coding (LOGCC).<
