Abstract
A foot-operated input device for use in combination with a computer includes a housing to which one or more track balls are mounted, and a series of switches mounted to the housing. The track balls are employed to control the position of the computer's cursor, cross hair or the like in response to an operator's foot movements. The switches are also actuated in response to the operator's foot movements, and function in the same manner as switches associated with a mouse. Alternatively, the switches can be employed to provide other inputs to the computer, such as programmable macro inputs, ASCII inputs or the like.
