Abstract
A new approach for optical Head Motion Tracker (hereafter HMT) is shown. In existing magnetic HMT, it is inevitable to conduct pre-mapping in order to obtain sufficient accuracy because of magnetic field's distortion caused by metallic material around HMT, such as aircrafts and vehicles. Optical HMT is commonly known as mapping-free tracker; however, it has some disadvantages in comparison with magnetic HMT. We have succeeded to develop a new optical HMT, which can overcome those disadvantages by integration with two area cameras, optical markers and inertial sensors with simple algorithm.
