We have developed several three-dimensional display systems that are matched to the human visual field characteristics. In this article, we describe our developed display systems, which are matched for the human communication in the close-range, medium-range, and distant rage categories. © 2010 SPIE. Source

NICT has conducted research and development on the 4K ultra-high definition image and its transmission technologies to realize the next-generation communications with 4 times resolution of the conventional HDTV (Hi-Vision), and completed the foundation for the 4K image technologies in the pioneer of the world. NICT's results on applied research and development based on the 4K image technologies are summarized in this paper. The author gives the prospect for applications of the 4K image technologies.

NICT is conducting research on Ultra-realistic communication since April in 2006. In this research, we are aiming at creating natural and realistic communication with people in remote places as if they are being there. For this research, we are studying 3D image technologies, 3D sound technologies, multisensory interfaces and also developing more objective measurement/ evaluation technique of feeling "presence" by using brain image and psychophysics. All of research results on Ultra-realistic communication are collected and published in this special issue. Preceding technical articles, outline of Ultra-realistic communication research is introduced in this section. Source

This paper describes a novel glasses-free 3D display of 360° optimized for tabletop tasks. For sharing 3D virtual objects on a flat tabletop surface naturally, we assume that the following conditions should be satisfied: (1) the tasks should not be disturbed and the working spaces should not be occupied, (2) the 3D images should be observed from arbitrary directions around the table, and (3) special 3D glasses should not be required for natural communication around the table. In this paper, we propose and implement the 3D display "fVisiOn" which fulfils the above whole conditions. The display employs circularly arranged projectors and a cylindrical- or a conical-shaped optical device that has a directional optical characteristic. Those devices are installed underneath the table not to obstruct the working space. One of the novelties of the proposed method is forming a ring-shaped viewing area above the table. When users look in this area, they can observe individual 3D images from each direction with correct perspective on the table such as a centerpiece. Source
