Abstract
Methods are provided for simulating a touch on a touch screen by applying a first signal to a first surface of the touch screen, applying a second signal to a second, opposing surface of the touch screen sensor, and changing the first signal relative to the second signal. Such methods can be used to simulate a touch to the center of the touch screen, for example. The simulated touch can be used in some embodiments to perform diagnostics and/or calibrations functions.
