Abstract

A hand-held Wii remote controller for a video game system is adapted to simulating motion control for a motorcycle, jet skis, or other vehicle steered by handlebars. The player holds the remote horizontally with one hand on each end, parallel to a TV display screen, and can control simulated motorcycle operations using inertial sensing. For example, rotating the handheld remote about its orthogonal X/Y/Z axes as pitch (throttle accelerate/decelerate), yaw (steering left/right), and roll (leaning left/right into a turn) can be used as control inputs. In addition, the player can emulate a more aggressive, real-world lean into turns by rocking side-to-side on an optional balance board.

Claims

1. A method for simulating the twist-grip throttle controller of a vehicle comprising:

receiving linear acceleration signals from a handheld controller, said linear acceleration signals indicating orientation of said handheld controller with respect to gravity;

determining, in response to said received linear acceleration signals, the angular orientation of said handheld controller in a twist direction controlled at least in part by wrist rotation; and

simulating virtual throttle control of a virtual vehicle in response to said determined angular orientation, including controlling, at least in part in response to said determined orientation, a vibration motor within said handheld controller to simulate end of travel of a vehicle twist-grip throttle controller.

2. The method of claim 1 further including determining angular orientation of said handheld controller in response to said sensed linear acceleration in a direction corresponding to a further wrist rotation about the axis of the forearm;

and

simulating lean of a simulated virtual vehicle at least in part in response to said determined further angular orientation.

3. The method of claim 1 wherein said handheld controller simulates a twist-grip controller disposed on simulated motorcycle handlebars.

4. The method of claim 1 wherein said sensed linear acceleration provides three orthogonal axes of sensed linear acceleration.

5. The method of claim 1 further including sensing the distribution of a game player'"'"'s weight on a platform, and further simulating degree of lean of said virtual vehicle at least in part in response to said sensed weight distribution.

6. The method of claim 1 further including using said sensed linear acceleration to at least in part control the attitude of a vehicle displayed on a display.

7. The method of claim 1 further including controlling a virtual vehicle displayed on a screen to at least partially maneuver in free space at least in part in response to said sensed linear acceleration.

8. The method of claim 1 further including sensing at least some aspect of attitude of said handheld controller using at least one gyro sensor disposed therein, and controlling said virtual vehicle at least in response to said sensing.

9. A system for playing video games based on game software, comprising:

a handheld controller including therein at least one linear accelerometer and a vibration motor;

a video game console wirelessly coupled to said handheld controller, said video game console executing game software responsive to said sensed linear acceleration and sending signals via said game console controlling the vibration motor; and

a storage medium operatively coupled to said game console, said storage medium storing instructions that receive and process said sensed linear acceleration and send commands to activate said vibration motor within said handheld controller, said stored instructions causing said handheld controller to simulate the twist-grip throttle control including end-of-travel characteristics thereof.
