METHOD AND APPARATUS FOR INTERACTING WITH A COMPUTER GENERATED PROJECTED IMAGE |
摘要 |
Disclosed is a method and apparatus for one or more operators to interact with a computer-controlled image projection system. An operator-controlled radiation projector projects a beam of radiation which may be visible or invisible on the image created by the computer-controlled image projection system. A position sensing device determines the position of the projected radiation relative to the projected image and provides position information to the computer. In a preferred embodiment, the computer can then generate an additional image at or related to the spot of radiation permitting the operator to draw or paint pictures on the computer-projected image. <IMAGE> |
