CA 2716403

An interactive surface computer with a switchable diffuser layer is described. The switchable layer has two states: a transparent state and a diffusing state. When it is in its diffusing state, a digital image is displayed and when the layer is in its transparent state, an image can be captured through the layer. In an embodiment, a projector is used to project the digital image onto the layer in its diffusing state and optical sensors are used for touch detection.

Linvention concerne un ordinateur à surface interactive muni dune couche de diffusion commutable. La couche commutable possède deux états : un état transparent et un état de diffusion. Lorsque la couche se trouve dans son état de diffusion, une image numérique est affichée et lorsquelle se trouve dans son état transparent, une image peut être capturée à travers la couche. Dans un mode de réalisation, un projecteur est utilisé pour projeter limage numérique sur la couche dans son état de diffusion et des capteurs optiques sont utilisés pour détecter le toucher.
