How a trackball works - Basically the trackball rolls against a trackball roller which then turns a slotted chopper wheel which is scanned by an optical sensor which converts your movement into digital information which is then sent to your computer via a USB connection.

Above is a close up photo of the chopper wheel sitting in the notch of the optical sensor.
