✦ Synopsis

In this study a non-contact tracker for calculating the angle of rotation of a HMD (head-mounted display) is proposed. The merit of our proposed method is that the computer will change the spatial view to match the user's head posture and keep the `immersion' sensation at high accuracy and precision. Our results are validated using moire fringes as an excellent HMD tracker.
