1. An interactive image projection system, comprising:
- a projection surface;
at least one sensor connected to said projection surface for detecting an object position of an object manipulatable by a user when said object is situated on said projection surface;
a computing device connected to said sensor for receiving said object position and generating at least one output in response thereto; and
first and second projectors disposed vertically above said projection surface and generally opposed to one another, said first and second projectors being configured for respectively projecting first and second respective projections of, respectively, first and second copies of an image onto said projection surface in register with one another as a single projected copy of the image thereon with each respective projection at least partially eliminating any shadow cast by said object on said image portion by blocking the other said respective projection.

Abstract
An interactive image projection system and method provides for projection of an interactive image on a projection surface. A copy of the image is broadcast by two projectors onto the projection surface in registration with one another to form a single projection copy on the surface. Sensors on the surface detect a position on the projection surface of an object manipulatable by a user and a computing device connected to the object generates an output in response thereto. The projectors are configured such that any shadow cast by the object in the path of a projection from one projector is at least partially eliminated by the projection of the other projector.

17. A method for projecting an interactive image, said method comprising the steps of:
-
a) projecting respective first and second projections of, respectively, first and second copies of an image onto a projection surface in register with one another to form a single projected copy of said image on said projection surface with, respectively, first and second projectors positioned vertically thereabove and generally opposite one another, each respective at least partially eliminating any shadow cast by said object on said projection surface by blocking the other said respective projection; b) detecting an object position on said projection surface of an object manipulatable by a user with at least one sensor connected to said projection surface; and c) based on said object position, generating at least one output with said computing device. - View Dependent Claims (18, 19, 20)
