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.
