Personal projected displays

Using Escritoire. Fovea straddling. Mark Ashdown, Phil Tuddenham & Peter Robinson

We are exploring technologies to build large projected displays and using these to experiment with new user interfaces.

The Escritoire uses two overlapping projectors to create a foveal display: a large display surface that has a high resolution region to allow detailed work. Multiple pen input devices are calibrated to the display to allow input with both hands. A server holds the documents and programs while multiple clients connect to collaborate on them.

More recently we have been looking at large high-resolution tabletop displays.
