A videoconferencing system that mimics head movements is being developed by Japanese company NTT, according to Tokyo news site, Diginfo TV. Users' faces are projected onto carefully positioned see-through screens which are moved by an arrangement of actuators. Face tracking technology traces the movement of a participants head which is then mimicked on the screen. Loudspeakers are positioned under screens so a voice will come from the person speaking.
Developers claim that movements, such as making eye contact and head nodding, have a huge influence on a conversation.
The system is still in development and NTT says it is working on perfect positioning for projection screens and advancing real-time operation.
