HUMAN-COMPUTER INTERFACE SYSTEM
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.
