G09G 5/08

US Classification:

345158, 345156, 345157

Abstract:

An interactive video display system. A display screen is for displaying a visual image for presentation to a user. A camera is for detecting an object in an interactive area located in front of the display screen, the camera operable to capture three-dimensional information about the object. A computer system is for directing the display screen to change the visual image in response to the object.

International Classification:

G09G 5/00
G09G 5/08

US Classification:

345156, 345157, 345158, 345159

Abstract:

A device allows easy and unencumbered interaction between a person and a computer display system using the person's (or another object's) movement and position as input to the computer. In some configurations, the display can be projected around the user so that that the person's actions are displayed around them. The video camera and projector operate on different wavelengths so that they do not interfere with each other. Uses for such a device include, but are not limited to, interactive lighting effects for people at clubs or events, interactive advertising displays, etc. Computer-generated characters and virtual objects can be made to react to the movements of passers-by, generate interactive ambient lighting for social spaces such as restaurants, lobbies and parks, video game systems and create interactive information spaces and art installations. Patterned illumination and brightness and gradient processing can be used to improve the ability to detect an object against a background of video images.

US Classification:

707100, 707 10, 707101, 707102, 7071041, 707200

Abstract:

A method and system for combining nodes in a file used for loading a node graph. The method includes defining a first node in the file as a mega-node of the file. The XML file includes a plurality of nodes arranged in parent/child relationships. The method proceeds by identifying a base node type for basing the mega-node upon.

US Classification:

382107, 382103, 715761, 725135

Abstract:

A method and system for processing captured image information in an interactive video display system. In one embodiment, a special learning condition of a captured camera image is detected. The captured camera image is compared to a normal background model image and to a second background model image, wherein the second background model is learned at a faster rate than the normal background model. A vision image is generated based on the comparisons. In another embodiment, an object in the captured image information that does not move for a predetermined time period is detected. A burn-in image comprising the object is generated, wherein the burn-in image is operable to allow a vision system of the interactive video display system to classify the object as background.

Appl. No.:

Inventors:

Matthew Bell - Palo Alto CA, US

International Classification:

G06F 3/033

US Classification:

345158, 345156, 345157, 348744

Abstract:

An interactive directed beam system is provided. In one implementation, the system includes a projector, a computer and a camera. The camera is configured to view and capture information in an interactive area. The captured information may take various forms, such as, an image and/or audio data. The captured information is based on actions taken by an object, such as, a person within the interactive area. Such actions include, for example, natural movements of the person and interactions between the person and an image projected by the projector. The captured information from the camera is then sent to the computer for processing. The computer performs one or more processes to extract certain information, such as, the relative location of the person within the interactive area for use in controlling the projector. Based on the results generated by the processes, the computer directs the projector to adjust the projected image accordingly. The projected image can move anywhere within the confines of the interactive area.

International Classification:

G09G 5/00

US Classification:

345156, 345158

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.
