PURPOSE: To provide an HMD (head mounted display by which the azimuth of the head of a viewer is detected with simple configuration without limit in the location and a displayed video image is changed depending on the detected azimuth of head. CONSTITUTION: In the HMD where virtual left and right images picked up by a 3-dimension camera are given to left right eyes by left right virtual image projectors 201L, 201R, the turning speed of the HMD is detected by angular velocity sensors 238, 239 comprising a vibration gyro using a piezoelectric ceramics and the azimuth of the HMD is calculated by the detected angular velocity to detect the azimuth of the head of a person wearing the HMD. The azimuth of the 3-dimension camera is set in matching with the azimuth of the head of the person wearing the HMD. |
