Abstract

Force feedback in a gaming controller is provided by a motion induction device having an untethered mass. The mass is accelerated and decelerated to provide directional force feedback to a user of the gaming controller. The forces may be applied in a game controller shaped to simulate a tennis racquet, baseball bat, gun, steering wheel, or golf club. A sensor may be included in the game controller to provide information for adapting the force feedback. For example, in a game controller simulating a golf club an accelerometer may measure the speed and motion of the golf club, and the game controller provides force feedback through the motion induction device to simulate impact with a golf club or train a user to swing in a desired motion.

Claims

1. A gaming controller, comprising:

a chassis;

a motion induction device fixedly coupled to the chassis, the motion induction device providing force feedback for the gaming controller;

a magnetic element movably positioned within the motion induction device, the magnetic element being movable along a first axis of the motion induction device;

at least one conducting coil wrapped around the motion induction device; and

a current control block coupled to the at least one conducting coil, the current control block being configurable to generate current through the at least one conducting coil to move the magnetic element along the first axis.

2. The gaming controller of claim 1, in which the force feedback provided is directional.

3. The gaming controller of claim 1, further comprising a sensor for providing at least one of motion, speed, and orientation information to the gaming controller, the information being used to adjust the force feedback.

4. The gaming controller of claim 1, in which the gaming controller is a baseball bat.

5. The gaming controller of claim 1, in which the gaming controller is a tennis racquet.

6. The gaming controller of claim 1, in which the gaming controller is a golf club.

7. The gaming controller of claim 1, in which the gaming controller is a gun.

8. The gaming controller of claim 1, in which the gaming controller is a steering wheel.

9. The gaming controller of claim 1, further comprising a potentiostat for adjusting an amplitude of the force feedback.

10. A method, comprising:

generating a current in a coil wrapped around an enclosure, the enclosure comprising a magnetic element movable along a first axis of the enclosure, the current causing the magnetic element to accelerate along the first axis away from an initial position to provide force feedback in a gaming controller to simulate an event; and

subsequent to the generating the current, causing the magnetic element to move back toward the initial position along the first axis.

11. The method of claim 10, in which the force feedback comprises at least one of simulating recoil in a gun, simulating a vehicle collision, and simulating a turn of a vehicle.

12. The method of claim 10, in which the force feedback comprises at least one of simulating a hit on a baseball bat, simulating a strike of a golf ball, and simulating a strike of a tennis ball.

13. The method of claim 10, further comprising:

receiving information from a sensor in the gaming controller; and

adjusting the force feedback provided in the gaming controller based on the received information.

14. The method of claim 10, further comprising:

receiving input from a potentiostat; and

adjusting an amplitude of the force feedback based on the received potentiostat input.

15. A gaming controller, comprising:

a chassis; and

means for accelerating an untethered mass, the accelerating means being fixedly coupled to the chassis, the acceleration means providing force feedback for the gaming controller.

16. The gaming controller of claim 15, further comprising a sensor for providing at least one of motion, speed, and orientation information to the gaming controller, in which the information is used to adjust the force feedback.

17. The gaming controller of claim 15, in which the gaming controller is at least one of a baseball bat, a tennis racquet, a golf club, a gun, and a steering wheel.

18. The gaming controller of claim 15, further comprising a potentiostat for adjusting an amplitude of the force feedback.

19. A computer readable medium tangibly storing a computer program for a game controller, comprising:

a sensing code segment that receives information from the game controller; and

a force feedback code segment that instructs force feedback in a motion induction device of the game controller based on the received information.

20. The computer readable medium of claim 19, in which the received information is at least one of motion, speed, and orientation of the game controller.
