Related Work The calibration of multi surface displays using a cameraprojector system is explored in the Office of the Future [8], where a complete 3D model of the display surfaces is extracted using structured light from a projector. That paper assumes that the intrinsic and extrinsic parameters of the camera and projector are known. We do not need to recover 3D scene geometry and the locations of our camera and projector ....

....on the floor directly points to the nearest exit. goggles not only are heavy and cumbersome, but they also require the fast and accurate tracking of the user s head to be effective. We are exploring the use of the ED projector in such environments. Unlike in previous works with static projectors [9, 10, 13], the rotating mirror expands the reach of projector to almost the entire room. It also enables the augmented reality image to follow an object around an environment (as long as there is a mechanism to track it) In the rest of this section, we examine augmented reality scenarios using the ....

....it is necessary to precisely register the position and attitude of the head of the user with the environment in real time. An examination of the state of art of the research in the area shows that this is currently achievable only in very constrained environments (see, for example, Raskar et al. [4]) The second challenge with head mounted methods for ubiquitous displays is that they do not work well in social contexts and collaborative tasks. If multiple users are looking at the same surface (for instance, a whiteboard) it is necessary to render exactly the same graphics on each user s ....

....The second method being studied to create ubiquitous displays utilizes portable devices such as laptops, PDAs, and mobile phones. Like head mounted displays, portable devices do not work well in social and collaboration tasks (except in very unusual conditions such as in multi player games [4]) and are a nuisance to carry and power. The third method involves embedding screens or similar interaction devices into the objects themselves, as proposed initially by Weiser [1] and more recently by Ishii [5] However, even if screens became extremely cheap, this approach requires a ....

We have been researching ways to create more immersive teleconferencing systems using wide field of view displays and 3D versus 2D imagery [24] [30] Unfortunately, real time extraction of 3D data is a very difficult and computationally demanding problem. In this paper, we present a hybrid system using both traditional computer vision and image based rendering approaches to provide 3D tele immersion. It consists of two steps. In the ....

....in texture memory and in the second pass the image is warped using texture mapping. This warped image when displayed by the projector appears perspectively correct to the user. Such two pass rendering techniques have been used for planar surfaces [15] as well as irregular display surfaces [6][13][14] 12] Some digital projectors also provide limited keystone correction facility by warping images before they are projected. The second pass of rendering increases the computation cost and in the case of immersive displays may also increase the rendering latency. In addition, texture mapping ....
