Abstract
A head tracking system for determining a head position of a user may include a light source configured to emit light onto a rectangular position sensitive device supported by a support structure such as headphones. The light emitted by the light source may generate a light spot on the position sensitive device. A head position determining module may determine the head position using the position of the light spot on the position sensitive device. The support structure may be configured to support the position sensitive device such that a head rotation results in rotation of the position sensitive device and a displacement of the light spot toward a corner of the rectangular position sensitive device.
