1. A human-machine interface device, comprising:
a touch receiver having a plurality of touch surfaces, each touch surface arranged in a distinctly different plane from the other touch surfaces;
an elastic strain sensing element having a base and a plurality of legs extending from the base, each leg in contact with or attached to an associated overlying touch surface such that pressure applied to a touch surface causes strain in an associated leg;
a first linear strain gauge mounted on each leg to detect strain along a first direction and a second linear strain gauge mounted on each leg to detect strain along a second direction that is different from the first direction; and
a processor that is configured to receive a signal from each of the first linear strain gauge and the second linear strain gauge and determine a command intended by a user operation (maneuver) of the human-machine interface device.
