We present an autostereoscopic display named TWISTER I (Telexistence Wide-view-angle Immersive STEReoscope, Model I), which is designed for a face-to-face telecommunication system called "mutual telexistence". By rotating display units that consist of LED arrays and a barrier around a viewer, TWISTER I can display panoramic stereoscopic images that can be observed without the use of special eyewear. This "glassless" feature is essential for applying this apparatus to mutual telexistence because eye contact is important in non-verbal communication.

    ABSTRACT: In this paper we report the development of TWISTER [3][8] (Telexistence Wide-angle Immersive STEReoscope), which realize the concept of "Mutual Telexistence". In contrast to conventional telexistence, where people in remote places can be appeared with a realistic sense of presence, in mutual telexistence, the figure of the observer him/herself can be displayed to remote users and all of the users can communicate as if they were in the same three-dimensional space. TWISTER is a cylindrical booth designed for mutual telexistence. It enables the user to view immersive and autostereoscopic images, and at the same time, it captures and reconstructs the image of the user inside with cameras positioned in-between the display unit. In previous reports on the development of TWISTER, we have introduced the development of display part [1]. In this report we discuss some methods to capture images of the user and render them in real time.

    ABSTRACT: Aiming at rich and useful communication in our daily home life, we propose a novel communication concept, "ComAdapter", in which people can mutually share their intention and emotion by exchanging their spontaneous behavior. ComAdapter can create shared space communication that allow us to communicate with another party in a remote location as though other party has entered our room. To achieve this, ComAdapter offsets the differences in the configurations of the rooms. In a simple preliminary system, body motions are successfully adapted and transmitted between two rooms with different layout. The success of the experiment confirms the validity and potential of ComAdapter.

    ABSTRACT: This paper describes in detail the design, development, and evaluation of the TWISTER III (Telexistence Wide-angle Immersive STEReoscope) and demonstrates how this system can display immersive three-dimensional full-color and live motion pictures without the need for special eye-wear. The device works as a cylindrical display by rotating 30 display units around an observer and presenting time-varying patterns, while immersive autostereoscopic vision is achieved by employing a "rotating parallax barrier" method. After explaining the principle, we discuss the designs and implementations for maximum performance in various aspects of the display. We also evaluate the display.
