Brief Patent Description - Full Patent Description - Patent Application Claims
BACKGROUND [0001] 1. Technical Field [0002] The present invention relates to an illumination system. [0003] 2. Background Art [0004] In robotic telepresence, a remotely controlled robot simulates the presence of a user. The overall experience for the user and the participants interacting with the robotic telepresence device is similar to videoconferencing, except that the user has a freedom of motion and control over the robot and video input that is not present in videoconferencing. The robot platform or surrogate typically includes a camera, a display device, a motorized platform that includes batteries, a control computer, and a wireless computer network connection. An image of the user is captured by cameras at the user's location and displayed on the robotic telepresence device's display in the surrogate's location. DISCLOSURE OF THE INVENTION [0005] The present invention provides an illumination control system including viewing illumination at a surrogate's location and recreating the illumination at a user's location as a relative perceived illumination. BRIEF DESCRIPTION OF THE DRAWINGS [0006] FIGS. 1A and 1B show an embodiment of a Mutually-Immersive Mobile Telepresence (E-Travel) System; [0007] FIG. 2 shows a luminance diagram illustrating four cameras in the surrogate's head pointing in different outward directions; [0008] FIG. 3 shows an embodiment of a camera on the surrogate's head and a light sensor assembly; [0009] FIG. 4 shows a luminance diagram similar to FIG. 2 where the luminance is scaled linearly from a midpoint by a computer; [0010] FIG. 5 shows a luminance diagram similar to FIG. 2 where the luminance is scaled linearly from the brightest video by a computer; [0011] FIG. 6 shows a luminance diagram similar to FIG. 2 where the luminance is scaled non-linearly from a midpoint by a computer; [0012] FIG. 7 shows a luminance diagram similar to FIG. 2 where the luminance is scaled with varying base illumination by a computer; and [0013] FIG. 8 shows a system 800 of mobile telepresencing according to an embodiment of the present invention. BEST MODE FOR CARRYING OUT THE INVENTION [0014] A Mutually-Immersive Mobile Telepresence System may have a robot device of a humanoid as well as a non-humanoid shape, which is referred to as a "surrogate". A user sits in a room that may show the surrogate's location and the surrogate may be located at a surrogate's location. Video and audio are transmitted between a user display and the surrogate. The user sees views radially outward on the user display and 360 degrees around from the center of the surrogate to have the feeling of being present at the surrogate's location by seeing it in a surround view, and the people or meeting participants at the surrogate's location have the feeling that the user is present by display panels on the surrogate showing images of the head of the user; i.e., the feeling of telepresence. [0015] The user sits or stands inside a display cube, with rear-projection surfaces on the front, back, sides, and optionally the ceiling showing the surrogate's location. Since the goal is to be mutually immersive, live color video images of the user centered on the user's head are acquired from all four sides of the user's location for transmission to the surrogate's location concurrent with projection of live color video surround from the surrogate's location on the four sides of the display cube surrounding the user. The user can move about inside the display cube, so head tracking techniques are used to acquire pleasingly cropped color video images of the user's head in real time. [0016] Referring now to FIGS. 1A and 1B, therein are shown a Mutually-Immersive Mobile Telepresence System 100, which includes a display cube 101 at a user's location 104 and a surrogate 106 at a surrogate's location 108. The surrogate 106 is connected to the display cube 101 via a high-speed network 110. [0017] The surrogate 106 has a surrogate's head 112 including a number of head display panels 114, such as four LCD panels. Video equipment in the form of one or more cameras, such as four surrogate's cameras 116-1 through 4, is positioned in the corners of the surrogate's head 112 to view and capture 360 degrees surround live video at the surrogate's location 108 for display on the display cube 101. An optional outward facing light sensor 117, facing up in FIG. 1A, may also be positioned on the top of surrogate's head 112 to detect the brightness of light overhead. [0018] One or more microphones, such as four directional surrogate's microphones 118, are positioned in the top corners of the surrogate's head 112 to capture sounds 360 degrees around the surrogate 106. One or more speakers, such as the four surrogate's speakers 120 are also positioned in the bottom corners of the surrogate's head 112 to provide directional audio of the user's voice. [0019] The surrogate 106 contains surrogate's computer/transceiver system 122 connecting the surrogate's cameras 116-1 through 4, the surrogate's microphones 118, and the surrogate's speakers 120 with the display cube 101 for a user 124. The surrogate's computer/transceiver system 122 also receive live video views of the user's head 126 from user's cameras 128-1 through 4 at the four corners of the display cube 101 and display the live video views on the head display panels 114 in the surrogate's head 112. [0020] The display cube 101 at the user's location 104 receives the video and audio signals at a user's computer/transceiver system 130. Video equipment provides views from the surrogate's cameras, such as the surrogate's cameras 116-1 through 4 in the surrogate's head 112, which are projected on projection screens 102 of the display cube 101 by projectors, such as four user's projectors 132-1 through 4. An optional variable brightness projector, such as a dimmable light 133, may be positioned facing inward, or down from above the user's head 126 in FIG. 1A.
