摘要：
An electronic device has a display, a controller, and a pair of haptic transducers connected to the display. The controller configures the haptic transducers to momentarily vibrate the display. A pair of sensors disposed on the display detects variations caused by the user touch in the vibrations. Based on an analysis of these variations, the controller can determine the location of the user touch on the touch-sensitive display.
