Recording of control signals
The touch-sensitive surface enables the touchpad to register the position of the finger on the touchpad and a press on the touchpad through the capacitive multitouch sensor system. The touchpad sends the detected finger coordinates and the detected pressure entries to the multimedia system control system. This then uses any swipe coordinates with one or more fingers as a basis to convert them into control signals.
The sensitivity setting of the detection takes place through the multimedia system.
