Method of operating a video gaming system

A method of operating a video game system, comprising:

• mechanically positioning 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;
• searching the video output feed from the camera with a computer processor to identify a location within the field of view of the camera where a non-visible light dot is present or absent upon actuation of a trigger of a light targeting peripheral that projects non-visible light onto the display screen;
• calculating the location within the field of view of the camera where the non-visible light dot is present or missing as a proportion of dimensions of the field of view of the camera;
• and
• translating the location of the presence or absence of the non-visible light dot within the field of view of the camera onto a location on the display screen by applying the proportion of said dimensions of the field of view of the camera to corresponding dimensions on the display screen.
