Abstract: Method is proposed of angular coordinates determination for observer's head relative to three mutually perpendicular axes of fixed (or tied to an object) coordinate system OXYZ (angle of roll, azimuth, elevation angle) by use of measuring system based on light-sensitive sensor with collimating lens fixed relative to coordinate system and LED lasers installed on head-mounted module HMM. Measuring device registers angular coordinates of narrow pencils of rays formed by LED lasers and provides determination of observer's head angular coordinates in real-time. Three angles of HMM can be determined by proposed method while no less than two LED lasers are in lens field of view with angle ? of set value and direction included between their axes. To provide specified measurement range of observer's head angles exceeding lens field of view LED lasers matrix is installed on HMM containing LED lasers allocated in several horizontal and vertical lines.
