[* red] A quick look at the last component hanging off the side of the motherboard reveals an Avago [http://www.avagotech.com/pages/en/navigation_interface_devices/optical_finger_navigation/adbm_a350|ADBM-A350|new_window=true] optical finger navigation module, responsible for detecting the position of the outer steel ring.
-[* icon_note] This component works similarly to an optical mouse's sensor, by snapping images of the inside of the ring and comparing sequential pictures as it spins by to determine position.
