Abstract
Determining a touch contact location is disclosed. A signal that has been disturbed by a touch input on a surface is received. The received signal is transformed to determine a spatial domain signal. The spatial domain signal is compared with an expected signal associated with a potential location of a source of a disturbance caused by the touch input. The touch contact location of the touch input is determined based at least in part on the comparison.
