MULTIPLE-SURFACE DISPLAY PROJECTOR WITH INTERACTIVE INPUT CAPABILITY
First Claim
1. A multiple-surface display projector comprising:
- a multiple-surface display controller adapted to distort an undistorted image into a distorted image;
a video projector coupled to the multiple-surface display controller and adapted to project the distorted image; and
a redirection device positioned to redirect the projected and distorted image onto a destination area of a destination surface.

Abstract
The present invention projects an image onto any surface in a room and distorts the image before projection so that a projected version of the image will not be distorted. The surface could be planar or non-planar. The present invention also allows for a projected image to be displayed at multiple locations along a surface or multiple surfaces. This allows a projected image to move from one location on a surface to another location on this or another surface, while the projected image remains undistorted through the move. Moreover, the present invention allows interaction between people and a projector. Interactive input, such as from mice, may be used with the versions of the present invention. Importantly, versions of the present invention can determine if an object is near an interactive item (such as a hyperlink) on the projected image. If so, the present invention can activate the interactive item. This allows a person to interact with a projected image.

15. A method to project a substantially distortionless image on any of a multiple of surfaces and for providing interaction with the substantially distortionless image, the method comprising:
-
distorting an undistorted image to create a distorted image, the step of distorting performed so that a projected image of the distorted image will be substantially undistorted when projected onto a destination area on a destination surface;
projecting the distorted image; and
redirecting projected light to a predetermined position selected to illuminate the destination area with the projected and distorted image.

22. A system to project a substantially distortionless image on any of a multiple of surfaces and for providing interaction with the substantially distortionless image, the system comprising:
a computer system comprising;
a memory that stores computer-readable code; and
a processor operatively coupled to the memory, the processor configured to implement the computer-readable code, the computer-readable code configured to;
distort an undistorted image to create a distorted image, the distortion performed so that a projected image of the distorted image will be substantially undistorted when projected onto a destination area on a destination surface;
output the distorted image to a projector suitable for projecting video; and
cause a redirection device to redirect projected light to a predetermined position selected to illuminate the destination area with the projected and distorted image. - View Dependent Claims (23, 24, 25, 26, 27, 28, 30, 31, 32, 33)

29. An article of manufacture comprising:
a computer readable medium having computer readable code means embodied thereon, the computer readable program code means comprising;
a step to distort an undistorted image to create a distorted image, the distortion performed so that a projected image of the distorted image will be substantially undistorted when projected onto a destination area on a destination surface;
a step to output the distorted image to a projector suitable for projecting video; and
a step to cause a redirection device to redirect projected light to a predetermined position selected to illuminate the destination area with the projected and distorted image.
