DETERMINING ORIENTATION IN AN EXTERNAL REFERENCE FRAME
First Claim
Patent Images
1. A system comprising:
- an orientation inferring subsystem including a monitor configured to visually observe a motion of an object relative to the monitor;
a position inferring subsystem including a target monitor configured to determine a coarse position of the object relative to the target monitor; and
a gaming subsystem for using the observed motion from the orientation inferring subsystem and the determined coarse position from the position inferring subsystem to control a game function.

Abstract
Orientation in an external reference is determined. An external-frame acceleration for a device is determined, the external-frame acceleration being in an external reference frame relative to the device. An internal-frame acceleration for the device is determined, the internal-frame acceleration being in an internal reference frame relative to the device. An orientation of the device is determined based on a comparison between a direction of the external-frame acceleration and a direction of the internal-frame acceleration.
