<p>PROBLEM TO BE SOLVED: To perform new information input and output by sharply displaying an aerial image having an input function and an output function integrated. SOLUTION: A visible light emission part as a display source emits visible light corresponding to an input key 26 and an aerial image generation part 10 which uses a couple of parabolic mirrors 20 and 22, etc., displays the aerial image 14 as a mirage of an input operation part 26. When the aerial image 14 is touched with a finger, its reflected light is detected by an optical detection part 28 and a controller 16 decides the operation position from the driving timing of the said visible light generation part and outputs a switch signal to the outside.</p> |
