ABSTRACT:
A technique is provided for entering certain information into a computer without the use of hands. A touch screen system which utilizes a grid of light beams across a display surface is modified. Instead of interrupting the light beam with the operator's finger, light blocking devices are moved into position along the periphery of the surface to shield a light detector at the position where otherwise such detector would be blocked by the operator's finger. The light-blocking device is moved by motors under foot control. In another approach, indicator arrays are placed along adjacent sides of a display surface. One indicator along each side is lit by foot control to represent a selected position. In still another approach, a cursor is selectively positioned on the display surface with foot-operated control circuitry. Once a position is selected, further inputs can be made even with the use of another, hand-operated, technique in a convenient, user friendly and prompt manner.
