ABSTRACT 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: An audiovisual interface equipped with a projector, an inclina-tion sensor, and a distance sensor for zoom control has been developed that enables a user to selectively view and listen to specific performers in a video-taped group performance. Dubbed Concert Viewing Headphones, it has both image and sound processing functions. The image processing extracts the portion of the image indicated by the user and projects it free of distortion on the front and side walls. The sound processing creates imaginary microphones for those performers without one so that the user can hear the sound from any performer. Testing using images and sounds captured using a fisheye-lens camera and 37 lavalier microphones showed that sound locali-zation was fastest when an inverse square function was used for the sound mixing and that the zoom function was useful for locating the desired sound performance.

    ABSTRACT: This paper reports the design, development, and prelim-inary performance evaluation of TWISTER II (Telexis-tence Wide-angle Immersive STEReoscope model II), an immersive full-color autostereoscopic display. The project is designed for the purpose of a face-to-face telecommuni-cation system called "mutual telexistence." The basic idea of mutual telexistence is the projection of human beings into a mutual virtual environment in real time. Each human user resides inside a booth with a spin-ning circular mechanism, which plays the role of both the display and the input device. With plural booths, each user can see the three dimensional figures of other users working in real time in the mutual virtual environment. We implemented the display partially, and confirmed its performance as a stereoscopic display of full-color still im-ages. It has been found experimentally to have enough tonal resolution and brightness. We studied the display gamma characteristics, as well as the display stability: to what extent a human observer can fuse an image with ro-tating LED arrays. We also focused on the performance of the "moving parallax barrier," which basically proved to contribute to stereopsis.

    ABSTRACT: We propose an expressive breathing method for a robot in accordance with its utterances. The synchronized expression is expected as a new physical modality to become like a living presence. Especially when the human-robot distance is near in intimate communications, anthropomorphized presences should naturally imitate activities of living beings, such as breathing. A stuffed-toy robot contains a speaker and a fan motor in its head to make simultaneous expressions of breathing and vocal sounds. The strength of the breath is determined by the total volume and power in the high frequency band.
