1. A surface computing device comprising:
- a surface layer having at least two modes of operation, wherein in a first mode of operation the surface layer is substantially diffusing and in a second mode of operation, the surface layer is substantially transparent;
a display means; and
an image capture device arranged to capture an image through the surface layer in the second mode of operation.

Abstract
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.
