<p>PROBLEM TO BE SOLVED: To prevent an explanation from being interrupted or the like while referring to an image by enabling a user to operate the changeover of image planes by a direct operation to the image projected on a screen. SOLUTION: One end of an optical fiber (bundle) 20 for image display is formed so as to introduce the light of the display image of a display device 12 and the other end is arranged matched with the display image on a display input board 24. One end of the optical fiber (bundle) 22 for sensing is arranged between the optical fibers on the other end side of the optical fiber 20 for the image display on the display input board 24 and the other end is mounted on a light receiving sensor 14. On the display input board 24, the display image at the display device 12 is projected through the optical fiber 20 for the image display. A CPU 10 obtains a light incident position on the display input board 24 on the basis of pointer light made incident from the optical fiber 22 for sensing detected by the light receiving sensor 14 and executes a prescribed processing corresponding to the position.</p> |
