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;

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, wherein said accelerometer is placed as close to a center rotational axis of said steering wheel as possible to eliminate any extraneous acceleration from rotation; and

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.
