Tele-guidance system using 3D-CG and real-time tracking vision

This paper describes the tele-guiding and information presentation system for an operator located at the remote place to show the location of the object which an instructor wants to point out. Three dimensional computer graphics (3D-CG) is being effectively used in the system while the object is not in the visual field of the operator. Real-time tracking vision is used to point out the object while it is in the operator's visual field. New type of a joystick was developed to control the 3D-CG, considering the characteristics of the human mobile action. The features of the system and some experimental results are presented.
