An novel binocular display with accommodative compensation is experimentally manufactured for use in fatigueless 3-D displays. The observed distance is measured two ways. One combines the gaze of one eye with a depth map of the image. The other way measures the convergence point using the gazes of both eyes. The former detects the depth correctly, but is limited to the case in which a real-time depth map of the field of view is obtained. The latter produces much depth detection error, but can be applied to an arbitrary image source.
