Zusammenfassung:PROBLEM TO BE SOLVED: To precisely and easily grasp a correlation between an eye-ball position and a target position by precisely inspecting an eye tracking function without fixing the head. SOLUTION: The movement of eye balls following a target projected on the display (4) of a goggle-type head set (5) is reflected by a half mirror (6) arranged on this side of it and imaged by an imaging camera (7). Then the image of the eye balls is image-processed to read the time change of eye ball positions as eye ball movement data. Then, the eye ball movement data and movement data of the target projected on the display (4) are superposed synchronously and displayed graphically. COPYRIGHT: (C)2004,JPO
