Grasp type areas. Color-intensity maps representing the hand total tendons tension (i.e. grasp strength) distribution with respect to the monitor screen reference system, while performing three different grasps: a) power, b) precision and c) lateral grasp. Each map has been built recording tension values and the corresponding mouse xy position whenever a stable grasp has been achieved by the mouse-driven hand.
