A foot operated data entry/input pad has a plurality of foot-operated buttons. The foot buttons may be used to enter data values, such as numbers or symbols separately or in combination. Each button is preferably 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. 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 help the user keep track of the data value as it changes and is entered. In alternative versions for input of instructions, single values or binary information, or for selection of items in a pull-down screen window, a pad may have two buttons provided adjacent a cursor controller, wherein the cursor controller and right and left click buttons are on an arc or on an angle.
