Abstract
A device and a method are disclosed for creating a virtual keyboard, mouse, or position detector. The device is an electronic keyboard that detects the position of a user's finger. The position of a user's fingers are detected by sending out a light beam parallel to the surface of, for example, a desk, and then detecting the position of a user's finger as the light beam is blocked by the finger. The position and movement of the user's fingers determine which key is to be struck or in which direction to move the pointer.
