The difference between this function and touchscreen_finger_points_multitouch is that touchscreen_finger_points_multitouch will return where the fingers currently are, while this function will return all the places where the fingers have previously been including where the fingers currently are. By traversing the list you can recreate the path that the fingers have moved.
