Abstract

A control wheel for controlling at least one function of a system by a user includes a moveable engagement wheel for engagement by the user and an actuator coupled to the engagement wheel for providing force or haptic feedback to the engagement wheel in response to movement of the engagement wheel. A sensor for sensing movement of the engagement wheel is provided and a control system is coupled to the sensor for receiving information about positioning and movement of the engagement wheel, and is also coupled to the actuator for controlling force to the engagement wheel. The control system also provides control of the at least one function of the system.

Claims

1. A control wheel for controlling at least one function of a system by a user, the control wheel comprising:

a moveable engagement wheel for engagement by the user, wherein the interior of the engagement wheel comprises a plurality of contact sensors;

an actuator coupled to the engagement wheel for providing force to the engagement wheel in response to movement of the engagement wheel;

sensing means for sensing movement of the engagement wheel; and

a control system coupled to the sensing means for receiving information about positioning and movement of the engagement wheel and for receiving signals from the plurality of contact sensors, and also coupled to the actuator for controlling force to the engagement wheel, the control system also providing control of the at least one function of the system.

2. A control wheel in accordance with claim 1 wherein the engagement wheel is coupled to the actuator via a gear drive transmission comprising an internal gear within the engagement wheel and a gear pinion coupled to the actuator via a shaft, the internal gear being meshed with the gear pinion.

3. A control wheel in accordance with claim 1 wherein the engagement wheel is coupled to the actuator via a belt coupled to a shaft of the actuator.

4. A control wheel in accordance with claim 1 wherein the engagement wheel is coupled to the actuator via a pulley coupled to a belt coupled to a shaft of the actuator.

5. A control wheel in accordance with claim 1 wherein the engagement wheel is directly coupled to a shaft of the actuator.

6. A control wheel in accordance with claim 1 wherein the engagement wheel is coupled to the actuator by contacting a pinion coupled to a shaft of the actuator.

7. A control wheel in accordance with claim 1 wherein the engagement wheel is coupled to the actuator via a flexible coupling.

8. A control wheel in accordance with claim 1 wherein the actuator comprises a DC motor.

9. A control wheel in accordance with claim 1 wherein the sensing means comprises an optical encoder comprising an optical encoder disk and an emitter/detector.

10. A control wheel in accordance with claim 1 wherein the sensing means comprises one of an analog potentiometer, a capacitive sensor, and a reflective emitter/detector and encoder bar.

11. A control wheel in accordance with claim 1 further comprising a switch shaft, and a switch guide in engagement with the switch shaft and coupled to the engagement wheel such that a switch is engageable by depressing the engagement wheel.

12. A control wheel for controlling at least one function of a system by a user, the control wheel comprising:

a base including a push select shaft;

a scroll wheel assembly comprising;

a moveable scroll wheel for engagement by the user, the scroll wheel comprising an internal gear provided within an interior of the scroll wheel, wherein the interior of the scroll wheel comprises a plurality of contact sensors;
