High-Resolution, Large-Area, Tiled Displays

Tele-immersion research at UNC focuses on the Office of the Future. Above, you see our long-term vision of what the Office of the Future will be -- an immersive environment providing a true sense of local presence to remote participants, an enhanced working environment for collaborators both local and remote, and a new paradigm for human-computer interaction.

The Office of the Future, through computers, digital projectors, and other devices, will be merged with the office of colleagues, whether in the same city or in another country. Video pictures of work associates will be projected into the spaces around you as you meet about and collaborate on projects, creating a strong feeling that your partners are in the room with you. To accomplish this feeling of presence, we are designing and building an ultra high-resolution, wall-filling projection display system composed of many overlapping, projected tiles with automatic calibration and blending. This design enables plug-and-play capability of a variable number and arrangement of tiles, blended into a seamless image.

Currently, we use a wide-field-of-view, single-center-of-projection camera cluster to capture panoramic images for display in the Office. The images are displayed in the office, in real time, using multiple projectors projecting onto the natural walls of the office. This display is monoscopic, two-dimensional, and perspectively correct for a single position.

Our immediate research goal is to display, using our office set-up, correct, three-dimensional, monoscopic, immersive images for a tracked participant.

To date, we have set up a display with 8 projectors, driven by both Intel-based and Silicon Graphics computers. Eventually we plan to increase the size of the display and the number of projectors used. Intel desktop machines are also being employed by staff and graduate students to develop software used in running the Office of the Future system.
