Sensors register when the light beams are disrupted, e.g. by placing your finger on the pad. This makes for an incredible precision and allows you to use familiar gestures from smartphones and surf pads, e.g. tap, scroll, pinch, zoom and swipe. All 8 buttons and touch key areas gives you easy access to commonly used actions and are all programmable to suit your own choices.
