INTERACTIVE SURFACE COMPUTER WITH SWITCHABLE DIFFUSER

摘要

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.
