Abstract

A racing car steering wheel assembly provides an input/output interface for a participant in a multimedia interactive electronic game. Two primary paddles on the underside of the wheel control throttle and braking functions, respectively. Secondary paddles or buttons may be included on either the side of the wheel for optionally controlling gear selection. Integral accelerometers are included for determining wheel rotation. Steering inputs are caused either by rotation about a fixed point to which the wheel may be affixed or by rotation in free air. A wired or wireless interface to a PC or game console provides communication with game software and optional wired or wireless communication between the user and other individuals. Switches and buttons may be included to emulate controls on real race cars and for inputting game information. A panel display and/or a decorative logo plate may be included on the wheel.

Claims

1. An apparatus for directional control in an interactive simulation environment, comprising:

a steering wheel;

a first primary paddle and a second primary paddle mounted on an underside of said steering wheel, said first primary paddle configured to control a throttle function and said second primary paddle configured to control a braking function; and

at least one accelerometer configured for inertial position sensing wherein, in response rotational operation of said steering wheel, where said steering wheel is unmounted and operated in free space, said accelerometer generates signals for directional control in said interactive simulation environment.

2. The apparatus of claim 1, further comprising:

a first switch for up-shift control; and

a second switch for down-shift control.

3. The apparatus of claim 2, any of said first switch and said second switch further comprising:

a secondary paddle located on said underside of said steering wheel, wherein said secondary paddle is smaller in size than each of said first primary paddle and said second primary paddle.

4. The apparatus of claim 2, any of said first switch and said second switch further comprising:

a button mounted on a front side of said steering wheel.

5. The apparatus of claim 1, further comprising:

a plurality of shift lights associated with said steering wheel.

6. The apparatus of claim 1, further comprising:

a rotary input device for control of any of brake bias, wing position, anti-roll bar position, and engine related controls.

7. The apparatus of claim 1, further comprising:

a replaceable panel located substantially in a center of said steering wheel.

8. The apparatus of claim 7, said replaceable panel comprising any of a liquid crystal display (LCD) panel, a multi-digit display, and a non-electronic panel having a graphic design thereupon.

9. The apparatus of claim 1, further comprising:

an audio communications interface associated with said steering wheel.

10. The apparatus of claim 1, further comprising:

a video communications interface associated with said steering wheel.

11. The apparatus of claim 9, said audio communications interface comprising any of:

a wired interface configured for attachment to a wired headset; and

a wireless interface configured for communication with a wireless headset.

12. The apparatus of claim 1, further comprising:

a mechanism configured to program said steering wheel, wherein the function of said first primary paddle and said second primary paddle is programmably reversible.

13. The apparatus of claim 1, further comprising:

a mounting device receiving and securing said steering wheel while allowing rotation thereof.

14. The apparatus of claim 1, further comprising:

a processor configured to determine orientation of said accelerometer based upon an angle difference from vertical and finding a trigonometric ratio between X and Y accelerations measured by said accelerometer.

15. An apparatus for directional control of a vehicle in an interactive simulation environment, comprising:

a steering wheel;

an inertial position sensor associated with said steering wheel and configured for sensing motion of said steering wheel in at least two axes; and

wherein said steering wheel is unmounted and operated in free space.

16. The apparatus of claim 15, wherein rotational movement of said steering wheel is sensed solely by said inertial position sensor.

17. A method for directional control in an interactive simulation environment, comprising the steps of:

providing a steering wheel;

providing a first primary paddle and a second primary paddle mounted on an underside of said steering wheel;

using said first primary paddle to control a throttle function;

using said second primary paddle to control a braking function; and

providing at least one accelerometer and using said accelerometer for inertial position sensing wherein, in response rotational operation of said steering wheel, where said steering wheel is unmounted and operated in free space, said accelerometer generates signals for directional control in said interactive simulation environment.

18. In an apparatus for directional control in an interactive simulation environment, comprising a steering wheel, and a first primary paddle and a second primary paddle mounted on an underside of said steering wheel, said first primary paddle configured to control a throttle function and said second primary paddle configured to control a braking function, a computer readable medium having stored thereon program instructions that, when executed by a processor, cause said apparatus to perform the steps of:

in response to rotation of said steering wheel, where said steering wheel is unmounted and operated in free space, receiving as an input inertial position sensing of at least one accelerometer;

generating from said signals a representation of said rotation of said steering wheel; and

using said representation of said rotation for directional control in said interactive simulation environment.
