摘要： The present invention relates to touch sensor detector systems and methods incorporating an interpolated variable impedance touch sensor array and specifically to such systems and methods for gesture recognition and associating a UI element with the recognized gesture. In one embodiment, the present invention provides a variable impedance array (VIA) system for receiving a gesture that includes: a plurality of physical VIA columns connected by interlinked impedance columns; a plurality of physical VIA rows connected by interlinked impedance rows; and a processor configured to interpolate a location and/or pressure of the gesture in the physical columns and rows from an electrical signal from a plurality of column drive sources (connected to the plurality of physical VIA columns through the interlinked impedance columns) sensed at a plurality of row sense sinks (connected to the plurality of physical VIA rows through the interlinked impedance rows).

摘要： The present invention relates to automotive interface systems and methods. In one embodiment, an automotive interface system includes a steering wheel and an integrated interpolated variable impedance array that comprises a grid of sensing elements. The sensing elements are configured to power on simultaneously and to simultaneously generate multiple currents along multiple current paths in response to sensing a touch wherein the amount of current generated by a sensing element of the grid is directly proportional to the force applied by the touch. The automotive interface system also includes an analog-to-digital converter (ADC) and a processor communicatively coupled to the interpolated variable impedance array that are configured to receive the multiple currents along multiple current paths and determine a location, a duration, an area, and a force of the touch from the multiple currents along multiple current paths.

摘要： One variation of a method for interfacing a computer to a human includes: detecting application of a first input onto a touch sensor surface and a first force magnitude of the first input; in response to the first force magnitude exceeding a first threshold magnitude, actuating a vibrator coupled to the touch sensor surface during a first click cycle and triggering an audio driver proximal the touch sensor surface to output a click sound during the first click cycle; detecting retraction of the first input from the touch sensor surface and a second force magnitude of the first input; and, in response to the second force magnitude falling below a second threshold magnitude less than the first threshold magnitude, actuating the vibrator during a second click cycle distinct from the first click cycle and triggering the audio driver to output the click sound during the second click cycle.

摘要： One variation of a method for detecting an input at a touch sensor—including a force-sensitive layer exhibiting variations in local resistance responsive to local variations in applied force on a touch sensor surface and a set of drive and sense electrodes—includes: driving a drive electrode with a drive signal; reading a sense signal from a sense electrode; detecting a alternating-current component and a direct-current component of the sense signal; in response to a magnitude of the direct-current component of the sense signal falling below a threshold magnitude, detecting an input on the touch sensor surface during the scan cycle based on the alternating-current component of the sense signal; and, in response to the magnitude of the direct-current component of the sense signal exceeding the threshold magnitude, detecting the input on the touch sensor surface during the scan cycle based on the direct-current component of the sense signal.
