This paper proposes multiview version of autostereoscopic display FLOATS (Fresnel Lens based Optical Apparatus for Touchable-distance Stereoscopy), which combines generation of floating real image and parallax presentation to show realistic 3-D image within the viewer's reach. Earlier versions of FLOATS have required a head tracker, physical motion control of filters or mirrors, and transformation of image in accordance with the viewer's motion to keep on presenting different images to each eye. To do away with these requirements, we propose two methods which realize multiview presentation to the viewer. One method is to use multiple LCD panels and multiple fixed mirrors instead of mobile mirrors. The other method is to use multiple projectors, fly-eye lenses, and fresnel lenses. Though the former system doesn't cost much, it is not practical to present more than 10 views. In the latter system it is practical to present more than 30 views, which can realize presentation of both horizontal and vertical parallax. With this technology the viewers can perceive undistorted 3-D space from any angle, which makes it possible for multiple viewers to observe 3-D image at consistent position from different angles at the same time.

The author presents a new version of FLOATS (Flesnel-Lens-based Optical Apparatus for Touchable-distance Stereoscopy) system. The autostereoscopic display FLOATS combines parallax presentation and real image generation by lenses to show realistic 3-D images within the reach of the viewer. In the conventional FLOATS, polarizing filters or liquid crystal shutters are used to separate images projected to the eyes, which has caused cross-talk noise and reduction of brightness. This paper proposes use of combined mirrors instead of filters or shutters to realize parallax presentation. In this system the images for the right eye and the left eye are displayed side by side on the screen. Then the combined mirrors reflect each image to shift it to the center so that the optical geometry of this system may be completely the same as the conventional FLOATS display. This new method avoids both cross-talk noise and reduction of brightness and enables presentation of more realistic 3-D image which gives less eyestrain to the viewer. In addition to it, a LCD panel can be used as the screen part of this system because it is only required to show two images side by side. As a result the size of the system is reduced compared with the conventional system.

A reality-enhanced autostereoscopic display system is presented. In this system, the viewers who do not wear any special glasses can perceive 3-D 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 3-D objects in the workspace near the viewer without interfering the viewers' motion. Smaller artificial parallax leads to 3-D perception with more reality and less eyestrain than the conventional 3-D displays. For parallax presentation an mobile filter which plays the role of stereoscpopic 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 3-D 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 suing texture mapping technique.
