Presenting images to an observer
First Claim
1. Apparatus for presenting images to an observer comprisinga controllable light delivery medium having a display region, andan automatic controller configured to control the light delivery medium in such a way as to enable the observer to perceive a first image only when the observer'"'"'s eye is in one motion state and a second image only when the observer'"'"'s eye is not in the one motion state, without relying on any change in the operation of the controller or the medium as the basis for enabling the perception of the first and second images.

Abstract
Images are presented to an observer using a controllable light delivery medium having a display region. The light delivery medium is controlled in such a way as to enable the observer to perceive any of more than one image based on the motion state of the observer'"'"'s eye and without relying on any change in the operation of the controller or the medium as the basis for triggering the perception of the more than one image.

2. Apparatus for presenting images to an observer, comprising
a light delivery medium extending in at least two dimensions, the light delivery medium bearing a field of light delivery areas that are independently modulatable, and a device arranged to modulate the respective light delivery areas in a succession of different patterns that are presented rapidly enough to invoke the persistence capability of the observer'"'"'s vision, enabling the observer to perceive a first image at the field of light delivery areas only by virtue of the persistence and the motion of the observer'"'"'s eye, the field of light delivery areas being arranged so that as the different patterns are presented, a second, different image may be perceived by the observer in the same region in which the first image may be perceived.

41. A method of presenting images to an observer on a light delivery medium extending in at least two dimensions, the light delivering medium bearing a field of light delivery areas that are independently modulatable, the method comprising
modulating the respective light delivery areas in a succession of different patterns that are presented rapidly enough to invoke the persistence capability of the observer'"'"'s vision, enabling the observer to perceive a first image at a region of the light delivery medium only by virtue of the persistence and the motion of the observer'"'"'s eye, and arranging the field of light delivery areas so that as the different patterns are presented, a second, different image may be perceived by the observer in the same region in which the first image is perceived.

47. Apparatus for presenting images to an observer, comprising
a light delivery medium bearing a stationary two-dimensional field of light delivery areas that are independently modulatable, the light delivery areas populating fewer than all of the possible positions in a rectangular grid of positions, and a device arranged to modulate the respective light delivery areas in a succession of different patterns that are presented rapidly enough to invoke the persistence capability of the observer'"'"'s vision, enabling the observer to perceive a first moving image at a region of the light delivery medium, the field of light delivery areas being arranged so that as the different patterns are presented, a second, different, static image may be perceived by the observer in the same region in which the first image is perceived, neither of the images being easily perceived from any of the patterns taken alone.
-
48. A medium on which is stored a computer program that is arranged to cause a processor to control a light delivery medium having a display region in such a way as to enable an observer to perceive a first image only when the observer'"'"'s eye is in one motion state and a second image only when the observer'"'"'s eye is not in the one motion state, without relying on any change in the flow of the computer program or the medium as the basis for enabling the perception of the first and second images.

49. Apparatus for presenting images to an observer comprising
a means for controllable light delivery, the means having a display region, and a means for automatically controlling the light delivery medium in such a way as to enable the observer to perceive a first image only when the observer'"'"'s eye is in one motion state and a second image only when the observer'"'"'s eye is not in the one motion state, without relying on any change in the operation of the controller or the medium as the basis for enabling the perception of the first and second images.
