Abstract

This paper describes an investigation results of optimum screen size and viewing distance (angle) for viewing ultra high-definition and wide-screen television (UDW), and the psychological effects of UDW images. First, it is found that a shorter relative viewing distance is preferable to that of the HDTV system and that the preferred viewing distance for UDW images depends not on relative figures using the image height, but instead screen size. Second, it is found that the preferred viewing angles coincide with the positions where the maximum combined effects of “potency” and “comfortableness” are obtained, and that, compared with the HDTV system, UDW images, when viewed at the preferred viewing angles, can give much higher level of emotional feeling with regard to both “potency” and “comfortableness”.
