Abstract

A computer interface for use with a computer simulation system. The interface includes a first grip portion and a second grip portion pivotably coupled to the first grip portion. An actuator is coupled to at least one of the two grip portions and is configured to provide feedback to a user.

Claims

1. A computer interface for use with a computer simulation system, the interface comprising:

a first grip portion;

a second grip portion pivotably coupled to the first grip portion; and

an actuator coupled to at least one of the first and second grip portions and configured to provide feedback to a user.

2. A computer interface in accordance with claim 1 wherein the actuator is coupled to both the first and second grip portions.

3. A computer interface in accordance with claim 2 wherein the actuator comprises a rotary motor.

4. A computer interface in accordance with claim 1 wherein the actuator is coupled to the first grip portion and comprises a rotary motor, a rotating shaft that extends into the second grip portion, and a cable coupled to the rotating shaft and the second grip portion.

5. A computer interface in accordance with claim 1 further comprising a spring coupled to both the first and second grip portions.

6. A computer interface in accordance with claim 1 further comprising at least one sensor for sensing angular rotation of a pivot coupling the first and second grip portions.

7. A computer interface in accordance with claim 1 wherein the feedback is at least one of a group comprising pushing the grip portions apart, pulling the grip portions together, vibration, torque, and noise.

8. A computer interface for use with a computer simulation system, the interface comprising a practice tool comprising an elongated portion and a handle, the handle comprising:

a first grip portion at a proximal portion of the elongated portion;

a second grip portion at a proximal portion of the elongated portion and pivotably coupled to the first grip portion; and

an actuator coupled to at least one of the first and second grip portions, the actuator being configured to provide feedback to a user.

9. A computer interface in accordance with claim 8 wherein the actuator is coupled to both the first and second grip portions.

10. A computer interface in accordance with claim 9 wherein the actuator comprises a rotary motor.

11. A computer interface in accordance with claim 8 wherein the actuator is coupled to the first grip portion and comprises a rotary motor, a rotating shaft that extends into the second grip portion, and a cable coupled to the rotating shaft and the second grip portion.

12. A computer interface in accordance with claim 8 further comprising a spring coupled to both the first and second grip portions.

13. A computer interface in accordance with claim 8 further comprising at least one sensor for sensing angular rotation of a pivot coupling the first and second grip portions.

14. A computer interface in accordance with claim 8 wherein the feedback is at least one of a group comprising pushing the grip portions apart, pulling the grip portions together, vibration, torque, and noise.

15. A computer interface in accordance with claim 8 further comprising at least one sensor for sensing at least one of motion and position of the elongated portion.

16. A method of providing feedback within a practice tool during computerized simulation, the method comprising:

providing a practice tool comprising an elongated portion and a handle, the handle comprising;

a first grip portion at a proximal portion of the elongated portion;

a second grip portion at a proximal portion of the elongated portion and pivotably coupled to the first grip portion; and

an actuator coupled to at least one of the first and second grip portions; and

providing feedback with the actuator to a user.

17. A method in accordance with claim 16 wherein the feedback is at least one of a group comprising pushing the grip portions apart, pulling the grip portions together, vibration, torque, and noise.

18. A method in accordance with claim 16 further comprising sensing angular rotation of a pivot coupling the first and second grip portions.

19. A method in accordance with claim 16 further comprising sensing at least one of motion and position of the elongated portion.

20. A method in accordance with claim 16 further comprising providing a spring coupled to the first and second grip portions and biasing the first and second grip portions one of either away from each other or towards each other with the spring.
