An interactive directed beam system is provided. In one implementation, the system includes
a projector, a computer and a camera. The camera is configured to view and capture …

This paper introduces a novel touch sensing system for a projected screen with a single
camera. To achieve touch sensing with camera image, there are two challenges to …

We address how a human-computer interface with small device size, large display, and
touch-input facility can be made possible by a mere projector and camera. The realization is …
