Evaluating the Legibility of Streoscopic Game Consoles

Recently, 3D technology has been developing and spreading into many aspects of our life; for example, in television and mobile phones. It is generally believed that during stereoscopic vision, a person' accommodation and convergence are mismatched when viewing 3D images and thus causing visual fatigue. During stereoscopic vision, while accommodation is fixed on the display showing a 3D image, convergence of the left and right eyes crosses at the location of the stereo-image. According to the findings presented in our previous observation, however, such explanations are mistaken. Results from our previous research found that accommodation is not fixed on the display and actually moved to suit convergence. We used a parallax barrier system for the 3D image in the previous study. In this experiment, we measured accommodation and convergence simultaneously using a handheld 3D game console (parallax barrier scheme).
