Patent attributes
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.
