A novel display system named gactive displayh was proposed for bi-directional telexistence system in 2004. It consists of a 5-bar spherical parallel mechanism, a LCD and 3 actuators. The LCD is moved by the parallel mechanism along a spherical surface whose center is at the head of the operator. Its motions are synchronized with a remote camera system. As a result, the operator can see anywhere in the remote environment with realistic sensation similar to a Head-Mounted Display (HMD). In addition, the facial information of the operator can be easily acquired because the monitor is separated from his/her face. This feature yields a big advantage compared with the HMD. Furthermore, it allows the operator to access peripheral devices very easily.
