Abstract

We present a prototype display system for group teleconferencing that delivers the proper views to multiple local viewers in different locations. While current state-of-the-art commercial teleconferencing systems can provide highdefinition video, and proper placement and scaling of remote participants, they cannot support correct eye gaze for multiple users. A display capable of providing multiple simultaneous views to each local observer and multiple aligned cameras are required for generating a distinct and spatially-appropriate image for each local participant. If each local participant can observe the remote participants from an appropriate angle, then it becomes possible for viewers to properly identify where other participants are looking.

Our system provides view-appropriate imagery for multiple users by spatially multiplexing the output of the display. We achieve this by placing a lenticular sheet over the surface of the display, which directs light from different pixels in different directions. With knowledge about the subset of the display surface each participant can see, it is possible to combine each of the remote cameras' images into a single composite image. This image, when viewed though the multiplexing layer, appears to be the appropriate camera image for each local participant. The prototype system uses a camera-based display calibration technique capable of properly evaluating which pixels are visible from an arbitrary viewpoint without a physical model of the display.

Scalable and view-independent calibration of multi-projector display for arbitrary uneven surfaces
Abstract
Most existing systems for calibrating multi-projector display suffered from several important limitations such as dependence on point of view, restriction on the display surface and moreover the number of projectors and using obtrusive markers. In ...
Easy Calibration of a Multi-projector Display System

In this paper, we present a method for the geometric calibration of a multi-projector display system. The method is such that in order to calibrate the system, the user is only required to place the projectors and capture a single image of the images ...
