Tabletop display providing multiple views to users
First Claim
1. A device comprising:
- a substantially horizontal tabletop surface;
a rotatable view-angle restrictive filter behind the tabletop surface and arranged to be rotated, in use, in a plane parallel to the tabletop surface, the rotatable view-angle restrictive filter comprising a plurality of closely packed tubes, each tube being held at one end in an upper plane and at another end in a lower plane and wherein the view-angle of the filter can be rotated in use by moving the lower plane and upper plane in a circular motion with respect to each other; and
a display system adapted to display view-specific images in synchronization with the rotation of the view-angle restrictive filter.

Abstract
A tabletop display providing multiple views to users is described. In an embodiment the display comprises a rotatable view-angle restrictive filter and a display system. The display system displays a sequence of images synchronized with the rotation of the filter to provide multiple views according to viewing angle. These multiple views provide a user with a 3D display or with personalized content which is not visible to a user at a sufficiently different viewing angle. In some embodiments, the display comprises a diffuser layer on which the sequence of images are displayed. In further embodiments, the diffuser is switchable between a diffuse state when images are displayed and a transparent state when imaging beyond the surface can be performed. The device may form part of a tabletop comprising with a touch-sensitive surface. Detected touch events and images captured through the surface may be used to modify the images being displayed.

11. A method of operating a device comprising a tabletop surface, a diffuser layer, a view-angle restrictive filter and a display system, the method comprising:
-
rotating the view-angle restrictive filter in a plane parallel to the tabletop surface, the view-angle restrictive filter comprising a plurality of tubes, each tube being held at one end in an upper plane and at another end in a lower plane, rotating the view-angle restrictive filter including moving the lower plane and upper plane in a circular motion with respect to each other; and displaying a sequence of images on the diffuser layer in synchronization with the rotation of the filter to provide view-specific images to users. - View Dependent Claims (12, 13, 14, 15)

16. A surface computing device comprising:
-
a touch-sensitive surface adapted to enable user input to the computing device; a diffuser layer electrically switchable between a diffuse mode and a transparent mode; a mechanically rotatable view-angle restrictive filter between the touch-sensitive surface and the diffuser layer and arranged to be rotated, in use, in a plane parallel to the touch-sensitive surface, the mechanically rotatable view-angle restrictive filter including a plurality of tubes, each tube being held at one end in an upper plane and at another end in a lower plane, the view-angle of the filter being rotatable by moving the lower plane and upper plane in a circular motion with respect to each other; a display system adapted to display view-specific images on the diffuser layer in its diffuse mode in synchronization with the rotation of the view-angle restrictive filter; an imaging system adapted to capture images beyond the surface through the diffuser layer in transparent mode; and a processor arranged to control the operation of the projection system and to update the images displayed based on user input and images captured by the image system. - View Dependent Claims (17, 18)
