1. A touch pad assembly, comprising: a touch pad having one or more sensors that map the touch pad plane into native sensor coordinates; and a controller that divides the surface of the touch pad into logical device units, receives the native values of the native sensor coordinates from the sensors, adjusts the native values of the native sensor coordinates into a new value associated with the logical device units and reports the new value of the logical device units to a host device, the logical device units representing areas of the touch pad that can be actuated by a user.
