Super High Definition (SHD) digital cinema distribution system with 8 million pixel resolutions has been developed. This system is called 4K Digital Cinema by Hollywood people. Hollywood studios are now making standard for digital cinema. Furthermore, SHD camera is developed to open the door to the new high quality image in the area of digital entertainment. In this paper, current progress of network distribution of SHD images over broadband networks.
Various video systems have been developed for the purpose of the stronger sense of presence, but the quantitative evaluation of the sense is very difficult. Subject evaluations and physiological responses have been used to evaluate it. This study aims to establish a clear quantitative relation between the viewing angle of the displayed images and the viewer's sense while watching still images with 6 variations of visual angle, which correspond to video systems ranging in resolution from high-definition (horizontal visual angle is approximately 30arcdeg.) to 4000-scanning-line Super Hi-Vision (100arcdeg.). The experimental apparatus was Super Hi-Vision system. We assessed the sense by subjective evaluations, and measured viewers' body sway, which is the response of a human equilibrium system, as an index of the sense. The results showed the quantitative relations between the evaluations and the viewing angle.
We are developing an auto-stereoscopic display system for the use of remote manipulation. Conventional auto-stereoscopic display systems have the problem that viewing-zone is narrow. For expanding viewing-zone,there is a method of eye-position tracking system. We report a method of eye-tracking system by the rotation of a concave mirror for horizontal and vertical tracking and by the movement of slits which restrict viewing-zone to the front and the rear.
The depth-fused 3-D (DFD) display is a novel device that presents depth information using a stack of two LCDs. In this study, we subjectively and objectively examined whether DFD display induces to more visual fatigue than 2-D displays. The results indicate (1) there were no statistically significant differences, between 2-D images and DFD images in terms of impairments of visual functions and (2) subjects responded more quickly when viewing DFD images than viewing 2-D images.
In this paper, research projects that promoted by the authors are described as followings; (1) a stereoscopic display using dynamic optical correction, (2) a body-image display using an illusion, (3) fragrance display using visual information.
TOPPAN has been developing new fields to a digital expression domain, based on the printing technology. The contents for students using virtual reality technology, "The sun and nine planets", show the possibility of digital communication.
This paper introduces an untethered force feedback system based on the Air Jet Interface. To create the tools for everyday life, it is necessary to develop untethered human interface technologies that do not constrain the user's activities. However, many devices in existing VR systems tether the user by wires or heavy body devices and so are annoying. We have developed a force feedback technique based on the use of air pressure toward an untethered human interface that is easy to use in everyday life. The basic idea of this force feedback interface is that air released from nozzles impacts the "air receiver" held by the user. The user perceives the air pressure as force and so feels as if he/she is touching the object. The current system employs multiple air jets arranged in a matrix to express the feel of touching three dimensional objects. In addition, a projection-based stereo display and an optical position tracking are employed to fully implement the untethered environment.
Computer visualization has been commonly applied for large-scale and detailed dataset. On the other hand, Visualization output of these kinds of data is too large to operate interactively, so reviewers sometimes give up interactive operation of the computer graphics output or reduce the detail of contained information in such data for visualization. In this paper, we introduce several SGI's visualization solutions for large-scale and detailed dataset.
