<p>PROBLEM TO BE SOLVED: To provide a posture angle detector in a head-mounted display usable in infinite space without being limited by place and environment wherein the device is used. SOLUTION: In the body 1 of a display, a sensor part 2 composed of first, second and third gyroscopes for detecting angular velocity around mutually perpendicular three shafts and first, second and third accelerometers for detecting acceleration around the three shafts is arranged. An arithmetic part 3 for respectively calculating the dynamic component of a posture angle based on the angular velocity outputted by the sensor part 2 and the static component of the posture angle based on the acceleration and selectively outputting the dynamic component of the posture angle and the static component of the posture angle as an actual posture angle corresponding to the movement of a user's head part is provided.</p> |
