Summary:The present invention relates to interpolated variable impedance touch sensor arrays for force-aware large-surface device interaction. An exemplary system for detecting a continuous pressure curve includes a plurality of physical variable impedance array (VIA) columns connected by interlinked impedance columns and a plurality of physical VIA rows connected by interlinked impedance rows. The system also includes a plurality of column drive sources connected to the interlinked impedance columns and to the plurality of physical VIA columns through the interlinked impedance columns as well as a plurality of row sense sinks connected to the interlinked impedance rows and to the plurality of physical VIA rows through the interlinked impedance rows. Further, the system includes a processor configured to interpolate the continuous pressure curve in the physical VIA columns and physical VIA rows from an electrical signal from the plurality of column drive sources sensed at the plurality of row sense sinks.
