CONFERENCE PROCEEDINGS FREE ACCESSA stereoscopic display using a curved directional reflection (CDR) screen and projectors is a promising approach towards realizing an immersive three-dimensional (3D) display system. A CDR screen consists of a corner reflective mirror sheet and a lenticular sheet. The CDR 3D display can provide bright and large images without wearing special glasses. Before now, we improved our 3D display to increase the number of possible observers and widen viewing area. We also showed the feasibility of an immersive desktop 3D display by developing compact projectors. These of our works on the 3D display systems are summarized.View full abstractDownload PDF (647K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this research, we improve image resolutio of our spherical immersive display by using HDTV system. By using a HDTV projector and a HD camera unit, the system has approximately 3-times higher resolution than NTSC based spherical immersive display theoretically. Also the aspect ratio of HDTV (16:9) enhances the effective pixel ratio of original images that captured by the camera unit. We made a prototype system. We evaluated the effectiveness of this method by measuring subject's eyesight. As a result, we verified resolution enhancement with this system.View full abstractDownload PDF (711K) -

CONFERENCE PROCEEDINGS FREE ACCESSHybrid hologram screen has the merit that it can control the size of view zone adequately. The screen is assumed to use for color display. But hologram screen invitably has color dispersion and color aberration. Hybrid hologram screen described here can decrease the dispersion and the aberration. Therefore hybrid hologram screen can realize make large screen size and adequate view zone. In this paper, we report the result of appraisal of view zone.View full abstractDownload PDF (441K) -

CONFERENCE PROCEEDINGS FREE ACCESSHolography is a technique that enables us to reconstruct 3D images in the space. Several reconstructing techniques using photorefractive crystals or systems with lenses have been studied. However, they have some drawbacks such that the size of the reconstructed images tends to be small, and the area of a view is to be limited by the lenses. Here we present a new reconstructing method with the use of a cattering of particles. The scattered particles play a role just as a screen. It enables us to observe relatively large 3D images easily.View full abstractDownload PDF (614K) -

CONFERENCE PROCEEDINGS FREE ACCESSWe have newly developed a prototype of the auto stereoscopic 3-D displays by using a newly developed LC panel with very large number of pixels. This 3-D display consists of a pinhole array instead of the Image Splitter we have developed so far. The pinhole array creates the horizontal and vertical parallax image with VGA resolution per one eye. And many viewers can observe 3-D images at the same time from wide viewpoints. The advantage of this display is tis simple structure and thus lower manufacturing cost will be expected for a future 3D-TV set. This research was performed in connection with the national project by NEDO (New Energy and Industrial Technology Development Organization) in Japan.View full abstractDownload PDF (515K) -

CONFERENCE PROCEEDINGS FREE ACCESSThis study in two-year plans from APril, 2002 aims at utilizing the result of TAO. It is the research and the development of a mark "a High Presence Tele-Co-learning system" which youth and general adult can share the impression and the joy with each about an advanced and a complicated technology. Important points of this system are how to develop a 3-dimensional image united with a video avatar of a suitable leader of that field and make a connection with science museums and other museums on a Giga-Bit-Network. It introduces to below about the function of this system, practical use of a network, a research-and-development matter, etc.View full abstractDownload PDF (547K) -

CONFERENCE PROCEEDINGS FREE ACCESSTelexistence, tele-existence, or telepresence, is an advanced form of tele-operation, which enables a human operator to remotely perform tasks with dexterity, providing the user with the feeling that he or she is present in the remote location. As a matter of fact, some fictitious robot control systems in novels, comics, animations, and movies precede real robot control systems. In this paper, we will review the history of telexistence robots, both in terms of current technology and science fiction, with paying special attention to display and operation aids.View full abstractDownload PDF (656K) -

CONFERENCE PROCEEDINGS FREE ACCESSTo date, companies all over the world have released a huge number of games incorporating state-of-the-art computer technologies. Recent computer-based game machines, which have evolved through several stages of technical innovation, constitute what may be called a brand-new interactive medium. We produced a commercially viable versio of a multi-view autostereoscopic display system that uses a lenticular array and a high-resolution color LCD panel. Such displays are expected to be particularly effective in the multimedia environment that will be provided by next-generation game machines and mobile communications terminals. This article discusses the effectiveness of our autostereoscopic display in terms of both the hardware and the software, taking account of the design of the final 3D image contents.View full abstractDownload PDF (559K) -

CONFERENCE PROCEEDINGS FREE ACCESSIn this research, we propose a new multi-projection system "D-vision". The D-vision uses a hybrid screen which consists of a central flat screen with eight projectors and a peripheral curved screen with sixteen projectors. The central flat screen and that upper and lower peripheral areas can realize stereoscopic high resolution images for user's central vision. The other peripheral areas composed with differently shaped surface elements are used for the peripheral vision. This hybrid screen effeciently realizes immersive projection display which surrounding user's field of view. The high quality stereoscopic images projected on that screen are generated with the parallel rendering using a PC-Cluster. We also implement a string-based force display and a locomotion interface using a turntable for multimodal virtual environments.View full abstractDownload PDF (767K) -
