Abstract

A foot operated mouse for controlling a computer, providing similar functions as a conventional hand operated mouse. The novel foot operated mouse has a base which rests on a horizontal pad or surface, and a separate platform for supporting the foot. A ball for generating positional signals based upon an x-and-y coordinate grid is fixed to the base. The foot platform is attached to the ball and can wobble, or simultaneously rotate and incline, thereon. Switch operators corresponding to conventional finger operated control buttons of a conventional hand operated mouse are provided. Preferably, these switch operators are hinged to the foot platform, and incline when depressed. In an alternative embodiment, the foot platform and switch operators are integral. In the latter embodiment, switch operation results from contact of the platform with the base. Preferably, the upper surface of the platform is inclined, thereby establishing a toe position and a heel position. In an alternative embodiment, one switch operator is located at the toe position and another at the heel position.

Claims

1. A foot operated controller that rests on a floor for generating computer command signals to a computer comprising:

a base having a top side and a bottom side, a ball signal generator attached to said bottom side of said base for generating position signals, said ball signal generator including a ball depending from said bottom side of said base, so that said ball contacts the floor;

a platform located on said top side of said base, said platform adapted to cooperate with and support a user'"'"'s foot, said platform engaged with a pivot means for pivotal movement with respect to said base;

support legs depending from said bottom side of said base, said support legs being disposed about said ball, where said support legs are in contact with the floor such that said base is held in a generally parallel relationship with the floor and that said ball is also held in contact with the floor and is universally rotatable within said base; and

switch means disposed on said platform for generating an execution signal when said platform pivots through a limited range about said pivot means in at least a first direction;

whereby

said controller is placed on the floor and the user'"'"'s foot may be used to both generate said position signals to a computer by movement of said platform and said base, along with said depending ball, on the floor, and to generate execution signals by activation, also by the user'"'"'s foot, of said switch means on said platform, thus allowing the user to operate mouse driven menus on the computer by means of one or another of their feet.

2. The foot operated controller according to claim 1, wherein said platform is disposed at an angle to said base, to support the natural inclination of a user'"'"'s foot.

3. The foot operated controller according to claim 1, wherein said platform can pivot through a limited range in relation to said base, and where said switch means comprises two switches, a first switch activating when said platform is pivoted in a first direction to the limit of the range and a second switch activating when said platform is pivoted in a second direction to the limit of the range.
