A video game has a plurality of gaming image frames for displaying gaming
images of the video game, and a plurality of crosshair navigation frames
interleaved among the gaming image frames. During gameplay of the video
game, an optical projection of the gaming image frames and the crosshair
navigation frames are video captured whereby a crosshair position is
navigated within the display of the gaming images of the video game based
on a cross-correlation of the video capture of two or more of the
crosshair navigation frames.
