Multi-function control device with force feedback
First Claim
1. A control device comprising:
- a housing;
a carrier coupled to said housing and operative to move with respect to said housing in a first rotary degree of freedom about a carrier rotary axis;
a first sensor coupled to said carrier and operative to sense said movement of said carrier, said first sensor outputting a first control signal;
a roller rotatably coupled to said carrier, wherein said roller moves with said carrier in said first rotary degree of freedom about said carrier rotary axis, said roller operative to rotate with respect to said carrier in a second rotary degree of freedom about a rotary axis of said roller; and
a second sensor coupled to said roller and operative to sense said rotation of said roller in said second rotary degree of freedom about said rotary axis of said roller, said second sensor outputting a second control signal.

Abstract
A control device including a housing and a carrier moveable with respect to the housing in a first rotary degree of freedom. A first sensor senses the movement of the carrier and outputs a first control signal. A roller rotatably coupled to the carrier rotates with the carrier in the first degree of freedom and rotates independently of the carrier in a second rotary degree of freedom. A second sensor senses rotary motion of the roller and outputs a second control signal. Preferably, an arm member coupled between carrier and housing pivots about an axis. A third sensor, such as a switch, can be used to detect when the carrier has been pushed in a direction substantially orthogonal to a plane of rotation of the arm member. Force feedback can also be provided in the rotary degrees of freedom of the control device.
