ABSTRACT:
A foot operated data entry pad has a plurality of foot-operated buttons. The foot buttons are used to enter data values—e.g., numbers or symbols separately or in combination. Each button is capable of entering different data values, preferably depending on the length of time that it is pressed or on the number of times that it is pressed in succession. A small controller may be included to allow the user to control the computer's pointer, allowing the user to switch between data entry fields, as with a mouse. A heel rest may serve as both a heel rest and a button/switch for sending an electric/electronic signal. An automated voice system, or other audible and/or visual indicator system, may also be included to help the user keep track of the data value as it changes and is entered. Various embodiments are capable of entering a variety of alphanumeric data rather than a simple binary-type data set, such as yes
o or on/off, or instructions, such as a joystick used with a flight simulator program. Multiple data entry pads may optionally be used in conjunction.
