Foot-operated key pad
A foot operated data entry pad has a plurality of foot 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. 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/no 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.
1. A data entry pad for a computer comprising a plurality of foot buttons, said foot buttons being configured to enter different data values according to a code of actuation of the foot buttons, the buttons being spaced-apart in a generally radial planar pattern on said pad, each of said foot buttons being distanced about 5-10 inches from the center of a heel support area also on said pad.
2. The pad of claim 1 , wherein the code of actuation depends upon how long the buttons are continuously depressed.
3. The pad of claim 1 , wherein the code of actuation depends upon how many times the buttons are depressed, released, and re-depressed.
4. The pad of claim 1 , which comprises a cursor controller further from the heel support area than said foot buttons.
5. The pad of claim 4 , which comprises a mouse control button further from the heel support area than said foot buttons.
6. The pad of claim 4 , which comprises a mouse control button in the heel support area.
7. A foot key pad for a computer, which comprises a cursor controller and a mouse controller button, the cursor controller and mouse controller button being spaced-apart in a generally radial planar pattern on said pad, and both said cursor controller and said mouse controller button being distanced about 5-10 inches from the center of a heel support area also on said pad.
8. The key pad of claim 7 , which comprises a plurality of mouse controller buttons.
9. The key pad of claim 8 , wherein one mouse controller button is in the heel support area.
