    摘要： A touch sensor detector system and method incorporating an interpolated sensor array is disclosed. The system and method utilize a touch sensor array (TSA) configured to detect proximity/contact/pressure (PCP) via a variable impedance array (VIA) electrically coupling interlinked impedance columns (IIC) coupled to an array column driver (ACD), and interlinked impedance rows (IIR) coupled to an array row sensor (ARS). The ACD is configured to select the IIC based on a column switching register (CSR) and electrically drive the IIC using a column driving source (CDS). The VIA conveys current from the driven IIC to the IIC sensed by the ARS. The ARS selects the IIR within the TSA and electrically senses the IIR state based on a row switching register (RSR). Interpolation of ARS sensed current/voltage allows accurate detection of TSA PCP and/or spatial location.

    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.
