Interactive projected video image display system
First Claim
1. A method of providing interaction with a projected video image comprising the steps of:
- using a computer to generate a video image, the video image containing at least one predetermined region having a controlled characteristic associated therewith;
projecting the video image on any surface capable of displaying a projected image;
introducing an object over the projected image for a predetermined minimum period of time;
visually recording the projected image;
capturing an image from the visual recording of the projected image which contains the object;
comparing the captured image to the computer generated video image to detect the presence of the object in relation to the at least one controlled characteristic; and
generating a control signal for actuating the computer in response to the presence of the object.

Abstract
An interactive projected image video display system which includes a computer for generating video images, a projection apparatus coupled to the video output port of the computer for projecting computer-generated video images onto a projection screen, and at least one video camera for visually recording the projected image. The computer includes a frame grabber board coupled to the video camera for capturing individual frames or series of frames from the video recording of projected image. The captured images are compared to the computer generated images to detect for the presence of recognizable features introduced onto the projected image by a user to instruct the computer to trigger a computer operation. The system can also simulates a mouse to be used with any off the shelf application that uses a regular mouse.

17. An interactive projected video image display system comprising:
-
means for generating a video image, the video image containing at least one predetermined region having a controlled characteristic associated therewith; means for projecting the video image onto any surface capable of displaying a projected image; means for visually recording the projected image; means for capturing an image from the visual recording of the projected image; image discrimination means for comparing the captured image with the generated video image and for detecting the presence of an object introduced onto the projected image and its relation to the at least one controlled characteristic; and means responsive to said image discrimination means for triggering a computer operation image when said introduced object is detected. - View Dependent Claims (18, 19, 20)

21. A method of providing interaction with a projected video image comprising the steps of:
-
using a computer to generate a video image, the video image containing a button; projecting the video image; introducing an object over the projected image for a predetermined minimum period of time; visually recording the projected image; capturing an image from the visual recording of the projected image which contains the object; comparing the captured image to the computer generated video image to detect the presence of the object, wherein the comparing of the capture image to the computer generated video image further includes; reading a block portion of the captured image corresponding to the location of the button; checking the block portion for the presence of the object; generating a control signal for actuating the computer in response to the presence of the object; and self testing to verify calibration of projected images with captured images, and wherein the self testing further includes; storing a first image and a second image, said first and second stored images each having a common predetermined location associated therewith, said second stored image further including an object disposed over its respective predetermined location; projecting said second stored image; comparing the projected second stored image with said first stored image; and triggering a predetermined computer operation in accordance with the relationship of the respective predetermined locations of said first stored image and said second projected stored image during comparison with each other.

22. A method of providing interaction with a displayed video image comprising the steps of:
-
using a computer to generate a video image, the video image containing a button; displaying the video image; introducing an object over the displayed image for a predetermined minimum period of time; visually recording the displayed image; capturing an image from the visual recording of the displayed image which contains the object; comparing the captured image to the computer generated video image to detect the presence of the object;
wherein the comparing of the capture image to the computer generated image further includes;reading a block portion of the captured image corresponding to the location of the button; and checking the block portion for the presence of the object; generating a control signal for actuating the computer in response to the presence of the object; self testing to verify calibration of displayed images with captured images, and wherein the self testing includes; storing a first image and a second image, said first and second stored images each having a common predetermined location associated therewith;
said second stored image further including an object disposed over its respective, predetermined location;displaying said second stored image; comparing the displayed second stored image with said first stored image; and triggering a predetermined computer operation in accordance with the relationship of the respective predetermined computer locations of said first and second stored images during comparison with each other.
