Official abstract text for this publication.
A video game system can include a console, a camera and a light targeting peripheral (LTP), where the LPT can direct non-visible light (e.g., infrared (IR) light) onto a display screen. The camera is positioned so that is can view the display screen, and can locate a non-visible light dot on the display screen during video game play. The system can be used with any size or type of electronic display (e.g., any type of television, computer screen, etc.), or any type of non-electronic display (e.g., projector screen) on which the video game can be projected.

What is claimed is: 1. A video game system, comprising: a console configured to transmit one or more visual or aural effects of a video game to a display screen; a camera freely positionable in a plurality of positions in front of the display screen so that it can view the display screen, the camera having one or more sensors configured to sense motion of the camera, wherein the position of the camera is calibrated relative to the display screen when the one or more sensors detect that the camera has been moved and prior to operation of the camera, the camera configured to communicate with the console; and a light targeting peripheral disposed on the front side of the display screen, the light targeting peripheral comprising a housing, a trigger movably coupled to the housing, and a non-visible light source, the light targeting peripheral configured to direct a non-visible light onto the display screen and to communicate with one or both of the console and the camera when the trigger is actuated by a user to move the trigger relative to the housing, the camera configured to locate a position on the display screen targeted by the light targeting peripheral upon the actuation of the trigger irrespective of a size and type of the display screen and to communicate said position to the console. 2. The video game system of claim 1 , wherein the camera comprises an optical filter configured to filter out visible light while allowing non-visible light to pass through a lens of the camera. 3. The video game system of claim 2 , wherein the optical filter is selectively actuated to filter out visible light during operation of the video game. 4. The video game system of claim 2 , wherein the optical filter is actuatable between a position in front of the lens to filter out visible light and a position out of alignment with the lens to allow visible light to pass through the lens. 5. The video game system of claim 4 , wherein the optical filter is positioned out of the way of the lens to allow visible light to pass through the lens during a calibration of the camera. 6. The video game system of claim 1 , wherein the light targeting peripheral is configured to cause an infrared light to be directed onto the display screen when the trigger is actuated by the user. 7. The video game system of claim 1 , wherein the light targeting peripheral communicates wirelessly with the camera. 8. A video game system, comprising: a console configured to transmit one or more visual or aural effects of a video game to an electronic display screen; a camera freely positionable in a plurality of positions in front of the display screen so that it can view the electronic display screen, the camera having one or more sensors configured to sense motion of the camera, wherein the position of the camera is calibrated relative to the display screen when the one or more sensors detect that the camera has been moved and prior to operation of the camera, the camera configured to communicate with the console, the camera comprising an optical filter mechanically actuatable to filter out visible light while allowing non-visible light to pass through a lens of the camera; and a light targeting peripheral comprising a housing, a trigger pivotally coupled to the housing, and a non-visible light source, the light targeting peripheral configured to direct a non-visible light onto the display screen and to communicate with one or both of the console and the camera when the trigger is actuated by a user, the camera configured to locate a position on the display screen targeted by the light targeting peripheral upon the actuation of the trigger irrespective of a size and type of the display screen and to communicate said position to the console. 9. The video game system of claim 8 , wherein the optical filter is selectively actuated to filter out visible light during operation of the video game. 10. The video game system of claim 8 , wherein the optical filter is actuatable between a position in front of the lens to filter out visible light and a position out of alignment with the lens to allow visible light to pass through the lens. 11. The video game system of claim 10 , wherein the optical filter is positioned out of the way of the lens to allow visible light to pass through the lens during a calibration of the camera. 12. The video game system of claim 8 , wherein the light targeting peripheral is configured to cause an infrared light to be directed onto the display screen when the trigger is actuated by the user. 13. The video game system of claim 8 , wherein the light targeting peripheral communicates wirelessly with the camera. 14. A video game system, comprising: a camera freely positionable in a plurality of positions in front of a display screen so that it can view the display screen, the camera having one or more sensors configured to sense motion of the camera, wherein the position of the camera is calibrated relative to the display screen when the one or more sensors detect that the camera has been moved and prior to operation of the camera, the camera comprising an optical filter movable in front of a lens of the camera to filter out visible light while allowing infrared light and configured to communicate with a console; and one or more light targeting peripherals comprising a housing, a trigger movably coupled to the housing, and an infrared light source, the one or more light targeting peripherals configured to direct an infrared light onto the display screen and configured to communicate with one or both of the console and the camera when the trigger is actuated, the camera configured to locate a position on the display screen targeted by the one or more light targeting peripherals upon the actuation of the trigger irrespective of a size and type of the display screen and to communicate said position to the console. 15. The video game system of claim 14 , wherein the optical filter is selectively actuated to filter out visible light during operation of the video game. 16. The video game system of claim 14 , wherein the optical filter is actuatable between a position in front of the lens to filter out visible light and a position out of alignment with the lens to allow visible light to pass through the lens. 17. The video game system of claim 16 , wherein the optical filter is positioned out of the way of the lens to allow visible light to pass through the lens during a calibration of the camera. 18. The video game system of claim 14 , wherein the one or more light targeting peripherals communicate wirelessly with the camera. 19. The video game system of claim 14 , wherein the one or more light targeting peripherals are two light gun controllers. 20. The video game system of claim 14 , wherein the one or more light targeting peripherals comprises a sensor that communicates one or both of location and orientation information of the one or more light targeting peripherals to control circuitry thereof, the control circuitry configured to communicate said information to one or both of the console and the camera to facilitate inertial tracking of the one or more light targeting peripherals.
