The goal of this research is to develop a head-tracked, stereo virtual reality system utilizing plasma or LCD panels. This paper describes a head-tracked barrier auto-stereographic method that is optimized for real-time interactive virtual reality systems. In this method, a virtual barrier screen is created simulating the physical barrier screen, and placed in the virtual world in front of the ...

Virtual Touch Screen, on a projected area, is a system in which the projection on any ordinary flat surface provides us a graphical work-field for controlling specific kind of operations without any sophisticated touch sensors. Moreover, an ordinary screen area can be transformed into virtual touch screen with the use of a webcam and a projector. The webcam can take the picture of an indicator ...

We propose a novel method to avoid stereo window violations at screen borders. These occur for objects in front of the zero parallax plane, which appear (physical) screen, and that are clipped one eye while still being visible other eye. This contradicts cues, particularly disparity, potentially resulting strain simulator sickness. In interactive dynamic virtual environments, where user control...

A transparent and colourless projection screen is fabricated by depositing a silver nanocube sub-monolayer on a titania thin film. Backward scattering of the silver nanocubes is enhanced by titania in the blue and red regions, to which human eyes are less sensitive. As a result, this screen, which is cost-effective even for large areas, allows projection of full colour images.

We describe a tiled-projection display system whose entire image is composed of twenty four patches of projection, sixteen of which are used for front projection and eight of which are used for rear projection on the center area of the screen. Eight pairs of the projectors are used to project stereoscopic images, the left-eye image and the right-eye image. The screen consists of differently sha...

We present the i-ConeTM: a new projection-based panoramic display system for virtual environments. The i-ConeTM uses conical screen geometry, resulting in optimized projector placement to create an extended workspace for standing participants in a front projection curved screen display with a very large continuous field of view. Improved acoustical properties of the conical screen geometry enab...

projection display, is a room-sized, five-screen system that can display both computer graphics and video images. Several Cabins connected via a broadband network form the Cabinet system. Cabinet includes video avatars—a key new technology for sharing virtual worlds. Using video avatars, we have experimentally evaluated the ability to express positional information between distant users. I mmer...

The literature often suggests that proprioceptive and especially vestibular cues are required for navigation and spatial orientation tasks involving rotations of the observer. To test this notion, we conducted a set of experiments in virtual environments in which only visual cues were provided. Participants had to execute turns, reproduce distances, or perform triangle completion tasks. Most ex...

The present paper discusses a method for robust face recognition that works even when only one image is registered and the test image contains a lot of local noises. Two types of facial image decomposition are compared both theoretically and experimentally. That is, we consider both a projectional decomposition, in which images are decomposed into individuality and other components, and a locat...

The so-called “blue-c” is a novel three sided immersive projection system, which has been especially designed to support telecollaborative teamwork [4]. Therefore, special projection screens are used, which can be switched to a transparent state electrically. The user is captured with sixteen cameras in total, standing outside of the projection room. These images are then processed to create a ...
