Foot-controlled computer mouse
First Claim
1. A computer mouse comprising:
- a housing including a top foot engaging surface, a bottom, and an interior;
roller means for transmitting foot movement by creating electronically readable mechanical movement along x and y coordinates corresponding with movement of a user'"'"'s foot and being movably supported and captivated with said housing and having a portion of a surface area thereof disposed in rolling engagement with a fixed surface to cause rotation of said roller means in a direction corresponding with direction of movement of an operator'"'"'s foot;
movement detection means within said interior of said housing for detecting directional movement of said roller means in accordance with the x and y coordinates;
signal generating means communicating with said movement detection means for generating an electrical signal corresponding with detected movement of said roller means along the x and y coordinates;
command entry means for entering a click command and including an electric switch operable between an on and off state in response to inwardly directed axial movement of said roller means relative to said housing, said electric switch being structured to generate an on/off signal upon entering said click command, and said roller means including at least one track ball supported on bearings, said bearings supported at the end of a cylinder, and said command entry means further including spring means within said cylinder for urging said track ball outwardly relative to said cylinder, wherein said track ball is structured to move inwardly upon application of inwardly directed pressure thereon, causing said spring means to compress, and actuating said electric switch to thereby generate said on/off signal, and said spring means being further structured to urge said track ball outwardly, away from said electric switch, upon release of said inwardly directed pressure on said track ball;
a micro processor for receiving said generated electrical signals and said on/off signal and for transmitting said electrical signals and said on/off to the computer; and
timer means for maintaining timing of said micro processor to receive and transmit said on/off signal and said electrical signals.

Abstract
A computer mouse for generating and delivering control signals to a computer includes a foot-operated device having a housing with a top foot engaging surface, a bottom surface and an interior with one or more rollers rotatably captivated therein and disposed in moving engagement with a fixed surface. Movement of the user'"'"'s foot is transmitted to the rollers, causing rotation of the rollers in a direction corresponding with the direction of foot movement. Detectors within the housing sense movement of the rollers in the x and y directions and translate the roller motion into electrical signals by generating pulses. A micro controller receives and interprets the pulses to determine linear direction of movement of the rollers in the x and y direction and transmits the interpreted data to a computer. Mechanical clicking operation is provided, wherein the one or more rollers are axially moved in response to downward force of the user'"'"'s foot on the mouse, causing a switch to be operated momentarily to an on state. Alternatively, the clicking operation is performed electronically, wherein light sensors detect foot movement by comparing sensed light with predetermined ambient light conditions.
