Interactive projection system and method
First Claim
1. A system of selectively projecting images, comprising:
- a light source configured to emit light toward a projection surface to define an illuminated area on the projection surface;
a camera directed toward the projection surface configured to detect the illuminated area on the projection surface;
a processing unit coupled to the camera configured to receive signals from the camera indicative of the position of the illuminated area in relation to the projection surface, the processing unit configured to utilize the signals received from the camera to create a first image and a second image to be projected on the projection surface; and
a projector separate from the light source and coupled to the processing unit configured to project the first image on the illuminated area of the projection surface, and a second image on an area of the projection surface that is not illuminated by the light source.

Abstract
A method and system of selectively projecting images is disclosed. An illuminated area is created on a projection surface by directing a light source to the projection surface. The illuminated area is detected with a camera. Electrical signals are transmitted from the camera to the projector, the electrical signals being indicative of the position of the illuminated area in relation to the projection surface. Based on the received electrical signals, an image and a second image are projected on the projection surface. The image is projected on the illuminated area of the projection surface. The second image is projected on an area of the projection surface that is not illuminated by the light source. Applications of this method and system include the projection of background and foreground images creating the illusion of an x-ray beam, the projection of a normal image and an overblown image creating the illusion of a magnifying light beam.

42. A system for selectively projecting images onto a projection surface, comprising:
-
a pointing device having a magnetic energy source, the magnetic source configured to generate directional magnetic energy in the vicinity of a projection surface; a magnetic receiver in the vicinity of the projection surface, the magnetic receiver configured to detect a position of the magnetic energy relative to the projection surface and direction of the magnetic energy from the magnetic source; a processing unit configured to receive signals from the magnetic receiver and indicate the position and pointing direction of the magnetic energy from the magnetic source in relation to the projection surface, wherein the processing unit utilizes the signals received from the magnetic receiver to determine a location coordinate on the projection surface to which a user is pointing the pointing device, wherein the processing unit creates a first image to be projected at the location coordinate on the projection surface, wherein the processing unit creates a second image to be projected on the projection surface at a location on the surface that is not the location coordinate on the projection surface; and a projector coupled to the processing unit configured to project the first image and the second image onto the projection surface. - View Dependent Claims (43, 44, 45, 46, 47)
