A personal projected display

— We have created a system called the Escritoire that uses two overlapping projectors to create a projected display for a personal computer. A large low-resolution region fills an entire desk while a high-resolution region accommodates the user’s focus of attention. We use commodity graphics cards to warp the projected images in real time to compensate for the unconstrained positions of the projectors. To allow documents to be shared in a visual space between remote participants we have split the software into a hardware-dependent client that handles the input and output, and a platform-independent server that controls the desk contents. We have conducted two sets of user studies, one with single users one with pairs at separate sites.
