PROJECTOR SYSTEM EMPLOYING DEPTH PERCEPTION TO DETECT SPEAKER POSITION AND GESTURES
First Claim
1. A projection system, comprising:
- a projection device for projecting at least one image onto a viewing surface;
an input device for acquiring a depth image of at least one foreground object relative to the input device;
processing logic configured to;
determine from the acquired depth image the position of the foreground object; and
modify the projected at least one image based on the position of the foreground object.

Abstract
A projection system that prevents projection light on a presenter and provides a gesture based interface for visual enhancements is disclosed. The system may include a projector camera system comprising a computer communicating an image to a projector, the projector projecting the image on a screen, a stereo camera unit mounted approximately in the plane of the screen or at the projector and directed toward the presenter and communicating with the computer, and software that interprets the stereo camera data to distinguish and manipulate foreground and background features. The foreground feature may be the presenter relative to the screen or to the audience and room, or the presenter'"'"'s hand relative to the presenter. The invention employs imaging stereo camera algorithms and techniques developed for foreground/background segmentation, image manipulation, and gesture recognition.

19. An interactive presentation system comprising:
-
a processor; a storage device coupled to the processor; and software means operative on the processor for; projecting at least one image onto a viewing surface; acquiring with a vision based input device a depth image of at least one foreground object; identifying from at least one of the acquired depth image and an image acquired from the vision based input device at least one command instructing the interactive presentation system to perform an action; determining from the acquired depth image the position of the foreground object; creating from at least one of the acquired depth image and an image acquired from the vision based input device a dynamic mask of the foreground object; and modifying the projected at least one image based on the dynamic mask. - View Dependent Claims (20)
