Audio interface for controlling a motion platform
First Claim
1. An audio-class computer peripheral to be connected to a computer comprising a general-purpose audio driver and configured to provide a motion signal to control a motion platform using said computer,said motion platform comprises motion actuators configured to impart movement on said motion platform from a digital audio-format signal comprising channels with a stream of motion samplessaid computer peripheral comprising:
- a computer interface configured to receive said digital audio-format signal to be provided using said general-purpose audio driver, said digital audio-format signal comprising motion samples, and configured to extract said motion samples from said digital audio-format signal; and
a motion platform interface configured to produce, from said motion samples, said motion signal configured to control movements of said motion platform, said motion platform interface comprising a mixing module configured to produce, using said channels, as said motion signal a stream of actuator samples configured to control each one of said actuators, said mixing module comprising a mix-enabled mode wherein said mixing module converts said streams of motion samples into said streams of actuator samples such that the position of the contact portions of said actuators with the motion platform are coplanar, wherein said mixing module provides at least one mapping between said channels and said actuators.

Abstract
The present description relates to the interfacing of a computer with a motion platform using a USB audio-class computer peripheral. The computer peripheral receives a digital audio-format signal according to the USB specification and provides a motion signal to up to four motion platforms. As the computer peripheral is a USB audio-class peripheral, no device-specific driver is required to play motion synchronously with a movie or a video game. The general purpose audio driver included in the operating system of the computer is advantageously used and the computer peripheral can alternately be used with any operating system comprising such a general purpose audio driver, such as Windows 2000, Windows XO or Mac OSX. The computer peripheral is seen by the computer as a USB sound card.
