Method and apparatus for variable impedence touch sensor array force aware interaction in large surface devices

A system for detecting a continuous pressure curve for a touch on a display device comprising:

• a variable impedance array (VIA), an array column driver, an array row sensor, and a processor;
• wherein the VIA includes interlinked impedance columns coupled to the array column driver and interlinked impedance rows coupled to the array row sensor;
• wherein the array column driver is configured to select the interlinked impedance columns based on a column switching register and electrically drive the interlinked impedance columns using a column driving source;
• wherein the VIA conveys current from the driven interlinked impedance columns to the interlinked impedance columns which are sensed by the array row sensor;
• wherein the array row sensor selects the interlinked impedance rows and electrically senses a state of the interlinked impedance rows based on a row switching register;
• and
• wherein the processor interpolates a location of the touch from the state of the interlinked impedance rows sensed by array row sensor.

A method for receiving a gesture formed on or about two or more sensor panels on a plurality of faces of a device comprising:

• detecting two or more touches at a first time at the sensor panels;
• determining that the two or more touches at the first time are arranged in a pattern corresponding to a predetermined gesture;
• determining a relative pressure between the two or more touches;
• associating the gesture with a user interface (UI) element based on the relative pressure between the two or more touches;
• and
• providing the confirming input to the UI element based on the relative pressure between the two or more touches.
