Abstract
Determining a touch contact object type is disclosed. A signal detected due to a touch input object contacting a touch input surface is received. At least a portion of the received signal is compared with one or more signatures of one or more touch input object types. A type of the touch input object contacting the surface is determined based at least in part on the comparison.
