Abstract
Techniques for interpreting motions of a motion-sensitive device are described to allow natural and intuitive interfaces for controlling an application (e.g. video game). A motion-sensitive device includes inertial and generates sensor signals sufficient to derive positions and orientations of the device in six degrees of freedom. The motion of the device in six degrees of freedom is tracked by analyzing sensor data from the inertial sensors in conjunction with data from a secondary source that may be a camera or a non-inertial sensor. Different techniques are provided to correct or minimize errors in deriving the positions and orientations of the device. These techniques include 'stop' detection, back tracking, extrapolation of sensor data beyond the sensor ranges, and using constraints from multi trackable objects in an application being interfaced with the motion-sensitive device.
