1. A sensing system, comprising: a keyboard adapted to receive first user input from a user; a sensing element adapted to obtain second user input from the user via a passive human interface device, wherein obtaining the second user input comprises: sensing, using the sensing element, a distribution of a static magnetic field emanating from a magnet of the passive human interface device; identifying, based on the sensed distribution, a change in at least one characteristic selected from a group of characteristics consisting of: a position of the magnet of the passive human interface device, and an orientation of the magnet of the passive human interface device; and identifying, based on identifying the change, an actuation of the passive human interface device; and an interface that is:
operably connected to the keyboard and the sensing element, the operable connection enabling the first user input and the second user input to be obtained by the interface, and adapted to provide the first user input and the second user input to a data processing system.
