  • Method and system for identification of user maneuver intention when operating with touch surface controller
    Patent number: 12236041
    Abstract: A human-machine interface device includes a touch receiver having a plurality of touch surfaces in distinctly different planes, an elastic strain sensing element having a base and a plurality of legs extending from the base and contacting an associated touch surface, a first linear strain gauge mounted on each leg to detect strain along a first direction and a second strain gauge mounted on each leg to detect strain along a second direction that is different from the first direction, and a processor configured to receive the signals from the strain gauges and determines a command operation intended by a user of the human-machine interface device.
    Type: Grant
