Abstract

A computer mouse including a base and rotatably coupled controller that permits only circular arc motions where only two radii of curvature are permitted and the radii differ in length. Hand translation is prevented by the device. A contoured hand engaging surface on the controller includes a raised palm seat with a spiral hand seat around the palm seat. Ergonomically-configured selectors are described. The hand motions permitted by the mouse are constrained by a toroidal shape at the interface between a base and a rotatably-movable controller. Selectors include one or more one finger activated keys mechanically linked to an internal electrical selector switch. A thumbwheel selector is also located in the controller.

b. a second subassembly that includes a convexity having a toroidal surface that projects into the concavity of the first subassembly;

c. a plurality of bearing elements, each bearing element interposed at least partially between the first and second subassemblies such that one of the subassemblies is supported by the other subassembly and such that relative movement is permitted between the subassemblies;

d. a motion detection system for detecting motion of one of the first and second subassemblies relative to the other and for generating movement signals;

e. one or more actuators for being contacted by one or more hand digits and for transforming digit motions and a circuit for generating command signals from the motions;

f. a circuit for transmitting movement signals and command signals, and;

g. wherein each subassembly includes one or more of;

i. a base for being supported by a work surface,

ii. a controller for being engaged with a hand;

iii. a portion of the motion detection system, and

iv. one or more of the actuators.

2. The computer mouse of claim 1 wherein the toroidal surface comprises a curved surface of an outer segment of a ring torus, the segment formed by passing a cutting plane that is parallel to an axis about which the ring torus was generated and the curved surface being disposed on the segment and opposite the cutting plane.

3. The computer mouse of claim 1 wherein the first subassembly comprises the base and the second subassembly comprises the controller.

4. The computer mouse of claim 3 wherein the motion detection system includes an illuminator for illuminating a portion of a target and an optical detector for detecting motion relative to the illuminated portion.

5. The computer mouse of claim 4 wherein the illuminator is disposed on the controller and the target is disposed on the base.

6. The computer mouse of claim 3 wherein the controller includes a hand-engaging surface for receiving a hand where the hand includes a central palm area, knuckle pads, a side palm, a heel, and a thumb base and where the hand-engaging surface includes a raised portion for contacting the central palm and a generally spiral-shaped depressed portion disposed about the raised portion for receiving one or more of the knuckle pads, side palm, heel, and thumb base.

7. The computer mouse of claim 3 wherein the controller includes a hand-engaging surface for receiving a hand where the hand includes a palm and a series of fingers, where surface includes palm-engaging portion, and where one or more of the actuators is disposed on the controller adjacent the palm-engaging portion.

8. The computer mouse of claim 7 wherein the one or more actuators have an actuation arc and wherein when the hand is engaged with the hand-engaging surface, one or more of the fingers is aligned with one of the one or more actuators such that an arc of motion of the finger generally coincides with the actuation arc.

9. The computer mouse of claim 3 wherein the controller includes a hand-engaging surface for receiving a hand where the hand includes a palm and a thumb and where one of the actuators is disposed on a side of the controller, and wherein when the hand is engaged with the hand engaging surface the thumb is in contact with the actuator.

10. The computer mouse of claim 9 wherein one of the actuators is a thumbwheel having an axis of rotation and wherein a longitudinal axis of the thumb intersects the thumbwheel axis of rotation.

11. The computer mouse of claim 1 wherein the first subassembly includes a base having a surrounding wall, and wherein the concavity is disposed interiorly of the surrounding wall;

the second subassembly including a hand-actuated controller configured to rest on the base;

the hand-actuated controller including an upper hand-engaging surface and a lower toroidal surface that at least partially projects into the concavity of the base; and

wherein the plurality of bearing elements are interposed between the base and the toroidal surface of the controller and enable the controller to move relative to the base.

12. The computer mouse of claim 11 wherein the motion detection system includes an illuminator disposed on the controller and a target disposed in the concavity of the base.

13. The computer mouse of claim 11 wherein the upper hand-engaging surface includes a raised palm seat for receiving the palm of a hand and a generally spiral shaped depression extending more than 180 degrees around the raised palm seat and adjoining a thumb area.

14. The computer mouse of claim 13 wherein the one or more actuators include a thumbwheel disposed adjacent and forwardly of the thumb area and a thumbwheel axis about which the thumbwheel is rotatable, and wherein when a hand is operably engaged with the hand receiver the axis that extends generally toward the thumb metacarpal-carpal joint of the hand.

15. A method of communicating hand movement to a computer, comprising:

a. supporting a controller on a base;

b. engaging a hand with the controller;

c. executing a motion of the hand to produce controller movement, the motion consisting of either or both of;

i. rotating the hand about a longitudinal axis of a computer mouse such that the hand traverses a first circular path, and

ii. rotating the hand about a transverse axis normal to the longitudinal axis such that the point on the hand traverses a second circular path,

wherein each of the first and second circular paths includes a radius, and the radius of the first circular path has a length different from a length of the radius of the second circular path;

d. detecting the movement of the controller relative to the base;

e. transforming the movement into data communicable to a computer; and

f. transmitting the data to the computer.

16. The method of claim 15 wherein supporting the controller on the base includes disposing a series of bearing elements within a concavity in the either the base or the controller and contacting a toroidal surface of the controller or the base with the bearing elements.

17. The method of claim 15 wherein engaging the hand with the controller includes contacting a central palm portion of the hand with a raised portion of a hand engaging surface on the controller.

18. The method of claim 15 wherein engaging the hand with the controller includes receiving at least a portion of a palm area that includes one or more of knuckle pads, a side palm, a heel, and a thumb base into a generally spiral-shaped depression in a hand engaging surface of the controller, the spiral shaped depression at least partially surrounding a raised palm portion of the hand-engaging surface.

19. The method of claim 15 including communicating movement of one or more digits of the hand by engaging one of the one or more digits of the hand with an actuator disposed on the controller.
