US 7,710,391 B2 · Processing an image utilizing a spatially varying pattern

Abstract

An interactive video window display system. A projector projects a visual image. A screen displays the visual image, wherein the projector projects the visual image onto a back side of the screen for presentation to a user on a front side of the screen, and wherein the screen is adjacent to a window. An illuminator illuminates an object on a front side of the window. A camera detects interaction of an illuminated object with the visual image, wherein the screen is at least partially transparent to light detectable by the camera, allowing the camera to detect the illuminated object through the screen. A computer system directs the projector to change the visual image in response to the interaction. The projector, the camera, the illuminator, and the computer system are located on the same side of the window.

Claims21

Dependent claims

An interactive display system, comprising:

an illuminator configured to emit light in a spatially varying pattern at a wavelength detectable by a camera but substantially invisible to the human eye, the light illuminating an object in an interactive area with the spatially varying pattern, wherein the spatially varying pattern creates an appearance of a texture on the object in the interactive area;
a camera configured to generate an image comprising the appearance of the texture on the object;
a computing device configured to
calculate a three-dimensional position of various points on the object based at least in part on the appearance of the texture on the object in the image, and
generate a visual effect based on the three-dimensional position of the various points of the object;
and
a video display for displaying the generated visual effect.
