Projection of Images onto Tangible User Interfaces
First Claim
Patent Images
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 to visible light and in a second mode of operation, the surface layer is substantially transparent to visible light; and
projection apparatus operable to project graphical data onto the surface layer in the first mode of operation and to project graphical data through the surface onto an object in the second mode of operation.

Abstract
A surface computing device is described which has a surface which can be switched between transparent and diffuse states. When the surface is in its diffuse state, an image can be projected onto the surface and when the surface is in its transparent state, an image can be projected through the surface and onto an object. In an embodiment, the image projected onto the object is redirected onto a different face of the object, so as to provide an additional display surface or to augment the appearance of the object. In another embodiment, the image may be redirected onto another object.

8. A method of operating a surface computing device comprising:
-
switching a surface layer between a substantially diffuse state and a substantially transparent state; in the substantially diffuse state, projecting graphical data onto the surface layer; and in the substantially transparent state, projecting graphical data through the surface onto an object. - View Dependent Claims (9, 10, 11, 12)

13. A surface computing system comprising:
-
a layer that can be electrically switched between a first state which is substantially diffusing to visible light and a second state which is substantially transparent to visible light; and projection apparatus, comprising at least one projector, arranged to project graphical data onto the layer in its first state and to project graphical data through the layer onto an object in its second state. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
