26. A method for operating a display capable of presenting content discernable in a presentation space, the method comprising the steps of:
-
selecting one of a general display mode and a restricted display mode;
presenting content to the presentation space when the general display mode is selected; and
performing, when the restricted display mode is selected, the steps of;
locating a person in the presentation space;
defining a viewing space comprising less than all of the presentation space and including the location of the person; and
presenting content so that the presented content is discernable only within the viewing space. - View Dependent Claims (27, 28, 29)

30. A method for operating a display capable of presenting content within a presentation space, the method comprising the steps of:
-
selecting content for presentation;
determining access privileges for a person to observe the content;
operating the display in a first mode wherein the content is displayed to the presentation space when the access privileges are within a first range of access privileges; and
operating the display in a second mode when the access privileges are within a second range of access privileges wherein during the second mode, a viewing space is defined comprising less than all of the presentation space and including the location of the person and content so that the presented content is discernable only within the viewing space.

31. A control system for presenting images to at least one person in a presentation space, the control system comprising:
-
a presentation space monitoring system generating a monitoring signal representative of conditions in the presentation space within which content presented by a display can be discerned;
an image modulator positioned between the display and the presentation space with the image modulator adapted to receive patterns of light presented by the display and to modulate the patterns of light emitted by the display so that the patterns of light are discernable only within spaces defined by the image modulator; and
,a processor adapted to determine the location of each person in the presentation space based upon the monitoring signal and to determine a viewing space for each person in said presentation space comprising less than all of the presentation space and also including the location of each person;
wherein the processor causes the image modulator to modulate the light emitted by the display so that the pattern of light emitted by the display is discernable only in the viewing space. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49)

50. A control system for a display adapted to present images in the form of patterns of light that are discernable in a presentation space, the control system comprising:
-
a presentation space monitoring system generating a monitoring signal representative of conditions in the presentation space;
an image modulator positioned between the display and the person with the image modulator adapted to receive patterns of light presented by the display and to modulate the patterns of light emitted by the display so that the patterns of light are discernable only within spaces defined by the image modulator; and
,a processor adapted to detect each person in the presentation space based upon the monitoring signal, to identify authorized persons based on this comparison; and
to determine a viewing space for each authorized person said viewing space comprising less than all of the presentation space and also including the location of the person;
wherein the processor causes the image modulator and the display to cooperate to modulate the light emitted by the display so that the pattern of light emitted by the display is discernable only viewing spaces for authorized persons. - View Dependent Claims (51, 52, 53, 54, 55, 56, 57, 58, 59)

60. A control system for a display adapted to present images in the form of patterns of light that are discernable in a presentation space, the control system comprising:
-
a presentation space monitoring system generating a monitoring signal representative of conditions in the presentation space;
an image modulator positioned between the display and the person with the image modulator adapted to receive patterns of light presented by the display and for modulating the patterns of light emitted by the display;
a processor adapted to select between operating in a restricted mode and a general mode;
with the processor further being adapted to, in the general mode, cause the image modulator and display to present content in a manner that is discernable throughout the display space and with the processor further being adapted to, in the restricted mode, detect each person in the presentation space based upon the monitoring signal, define viewing spaces for each person in the presentation space and cause the image modulator and display to cooperate to present images that are discernable only within each viewing space. - View Dependent Claims (61, 62, 63)

64. A control system for a display adapted to present light images to a presentation space, the control system comprising:
-
a detection means for detecting at least one person in the presentation space;
an image modulator for modulating the light images;
a processor for defining individual viewing spaces around each person with each viewing space comprising less than the entire presentation space and for causing the image modulator and display to display content only to the individual viewing spaces. - View Dependent Claims (65, 66, 67)

68. A control system for a display adapted to present light images to a presentation space, the control system comprising:
-
a detection means for detecting at least one person in the presentation space;
an image modulator for modulating the light images;
a processor adapted to obtain images for presentation on the display, to determine a profile for the obtained images and to select a mode of operation based upon information contained in the profile for the obtained images, wherein the processor is operable to cause the display to present images in two modes and selects between the modes based upon the images profile information, and wherein in one mode the images is presented to the presentation space and in another mode at least one viewing space is defined around each person with each viewing space comprising less than the entire presentation space and to cause images to be formed on the display in a way such that when the images are modulated by the image modulator so that the images are only viewable to a person in the at least one viewing space. - View Dependent Claims (69)
