<p>PURPOSE:To attain the operation of a computer device by projecting the picture of a menu screen or the like from a computer device by a projector device, and designating the menu with a write pen or the like. CONSTITUTION:The picture signal of the menu screen or the like from a computer 11 is projected through a projector part 12 on a screen 13. When a light such as an infrared ray from an infrared ray projecting part 14 is projected on a required menu position, the light is image picked-up by a camera 15, and inputted to a light position detecting part 16, the projected position of the light is detected, and a pertinent signal is inputted through an outputting part 17 to the computer 11. The computer 11 operates the switching of the screen according to the input. Also, the projector part 12 and the camera 15 operate scanning in a synchronizing state according to a synchronizing signal from a synchronizing signal generating part 18, and the light position detecting part 16 detects the position irradiated with the light by using the synchronizing signal as a reference.</p> |
