ABSTRACT:
An image forming device is adapted for placement on a surface on which pictures or characters are drawn or displayed. The image forming device includes a lens member including a plurality of distributed-index rod-like lens elements disposed in juxtaposed relationship with each other in a matrix-like arrangement and operable to map the pictures or characters as a visual real image on substantially one image plane in the air spaced from the surface. A touch-less display switch for use with a display device includes a sensor in addition to the lens member as in the image forming device. The sensor has a detection area corresponding to at least a part of the formed image on the image plane and operable to detect an object entering the detection area in a non-contact manner.
