Abstract:
Determining touch contact locations is disclosed. A signal that has been disturbed by touch contacts of 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 potential locations of sources of disturbances caused by the touch contacts. The locations of the touch contacts of the touch input are determined based at least in part on the comparison.
