Abstract
A method provides tactile feedback emulating a click like feedback provided by one or more low cost, thin piezoelectric devices (142) to an input device (110) of an electronic device (100), the piezoelectric devices (142) being driven by two or more low voltage pulses (804, 806) within the temporal acuity of human touch.
