Displaying stereo 3D images without requiring the viewer to wear glasses. Also called "auto 3D" or "glasses-free 3D." Although the Nintendo 3DS game console has been very successful, the distance from the screen to the user is short, and the viewing angle is narrow (see
parallax 3D). When creating autostereoscopic TVs with large screens, the wider viewing angle presents many challenges. One solution is to provide numerous viewing angles per frame of video. Stream TV Networks provides glasses-free 3D for TV (see
SeeCube). See
