Head Tracking System with Improved Detection of Head Rotation

摘要

The application relates to a head tracking system determining a head position of a user, comprising a light source (10) emitting light onto a rectangular position sensitive device (100) provided in a support structure (200). The light emitted by the sight source generates a light spot on the position sensitive device, and a head position determining module (170) is provided using the position of the light spot on the position sensitive device to determine the head position wherein the support structure (200) is designed to support the position sensitive device (100) in such a way that a head rotation results in a displacement of the light spot to a corner of the rectangular position sensitive device.
