Abstract
A signal to be used to propagate a propagating signal through a propagating medium with a touch input surface is sent. The propagating signal has been allowed to propagate through the propagating medium to a plurality of receivers coupled to the propagating medium. A received signal affected by a touch input object contacting the touch input surface is received. At least a portion of the received signal is compared with one or more reference signals of one or more touch input object types.
