This article presents useful observations that point to the fact that video users seem to have higher expectations of the medium that the video can really afford. This is evident in the reduced effectiveness of hand gestures, eye contact, and gaze awareness, as compared with face-to-face situations. In addition, the difference in locations of the input (camera) and output (image) prompt the user to gesture to the image, and not to the other person (that is actually "seeing" through the camera).
Some solutions to these issues is to provide eye contact, gaze awareness and increase the area being shown to at least the upper body.
