Patent ID: 7369100

Claim:
A control system for a display, the control system comprising: a presentation space monitoring system sampling a presentation space within which images presented by the display can be observed, and generating monitoring signals from which the location of people in the presentation space can be determined; an image modulator positioned between the display and the presentation space with the image modulator adapted to control the spatial distribution of image light emitted by the display so that light that is emitted by particular portions of the display travel to particular areas in the presentation space; and a controller adapted to determine the location of each person in the presentation space based upon the monitoring signal, to determine an individual viewing area for each located person, and to obtain at least one channel of content for presentation to each person; wherein the controller is further adapted to cause the display to present a combination image with images from each channel of content obtained for each person arranged in the form of a pattern of light that is spatially distributed by the image modulator to the viewing area determined for that person; wherein the processor is further adapted to analyze the monitoring signals during presentation of the content to detect movement of a person during presentation of the image content and to adjust the viewing area used to present content obtained for each moving person so that the content obtained for the moving person can be viewable by the person; and wherein the controller further analyzes the monitoring signals to detect when one person moves to a location that coincides with the viewing area of at least one other person, determines content for presentation to both persons based upon privileges associated with both persons, obtains the determined content and presents the determined content so that it is observable in a common viewing space occupied by the people.
