The human angle

Videoconferences can be daunting, with everyone staring directly at the
camera. The Human Factors Institute of the Netherlands applied research
organisation, TNO, has found that the conferences are more effective if each
participant is filmed with several cameras. If people see the other participants
at an angle—the view that they would have if they were all sitting around
the same table—they exchange twice as much information as people at
single-camera videoconferences.
