Zusammenfassung:Visible light is generated from a visible light generating unit (26) and formed by a pair of parabolic mirrors (20, 22) into an aerial image (14) suspended in space. The light reflected by touching the aerial image (14) with a finger is detected by a photodetecting unit (28) which supplies a signal to a controller (16). The controller (16) discriminates the signal according to a driving timing sequence of the visible light generating unit (26) and outputs a switch signal.
