A method of operating a video game system can include applying an optical filter in a field of view of a camera to filter out visible light and allow the camera to view non-visible light directed at a display screen positioned within the field of view of the camera. The method can also include processing the video output feed from the camera with a computer processor to identify a location of a non-visible light dot within the field of view of the camera that is projected onto the display screen by a light targeting peripheral unit. The method can also include calculating the location of the non-visible light dot within the field of view of the camera as a proportion of one or more dimensions of the field of view of the camera and translating the location of the non-visible light dot within the field of view of the camera onto a location on the display screen.

Method of operating a video gaming system

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.

A method of calibration a video game system can include removing an optical filter that filters out visible light from a field of view of a camera to allow the camera to view visible light. The method can also include displaying a calibration image on a display screen located within the field of view of the camera, processing the video output feed from the camera with a computer processor to identify the calibration image, and calculating with the processor coordinates that represent corners of the display screen in the field of view of the camera once the calibration image is identified.

A method of filtering noise in a three-dimensional position measurement system comprising receiving distance data representative of the respective distances between at least four spatially dispersed known points and an unknown point, performing triangulation calculations to determine at least two solutions to the three dimensional position of the unknown point relative to the known points, calculating a symmetrical bounding surface such as a sphere or cube which just encloses the said solutions, comparing the maximum dimension of the bounding surface with a first predetermined error threshold, and if the maximum dimension is less than the first error threshold, determining the center position of the bounding surface and outputting the center position as a noise-filtered position for the unknown point.

According to various embodiments, the invention provides a method for establishing communication between a computer program in a computing system and a controller held in a hand of a user, comprising: capturing image data in a capture area in front of a display, the capturing configured to identify a two-dimensional location of the controller in the capture area; and capturing one-way sound communication between a location proximate to the display and a location at the controller, the sound communication being used to compute a third-dimensional location of the controller in the capture area.
