abstract

A reality-enhanced autostereoscopic display system is presented. In this system, the viewers who do not wear any special glasses can perceive 3D images within their hands reach with little sense of incongruity. The feature of this system is combination of real image generation and parallax presentation. Real image of the display in the back is generated in the air by using Fresnel lenses, which has made it possible to narrow artificial parallax to display 3D objects in the workspace near the viewer without interfering the viewers' motion. Smaller artificial parallax leads to 3D perception with more reality and less eyestrain than the conventional 3D displays. For parallax presentation a mobile filter which plays the role of stereoscopic goggles is set between the display in the back and the Fresnel lenses and is controlled so that it follows the motion of the viewer to keep on presenting different images to each eye. To present undistorted 3D space the optical path including refraction by Fresnel lenses is calculated and the image on the screen is updated based on it. Real-time undistorted image presentation to unrestricted eye positions is realized by using texture mapping technique.
