Abstract
A method for detecting a touch event on a touch panel comprises obtaining at least first and second signals from at least two sensors where the at least first and second signals are responsive to a touch event. A first amplitude magnitude associated with the first signal is calculated and a second amplitude magnitude associated with the second signal is calculated. A magnitude ratio is determined between the first and second amplitude magnitudes, and a touch location is identified based on the magnitude ratio.
