64. A non-transitory processor-readable storage medium having stored thereon processor-executable instructions configured to cause a processor to perform operations comprising: receiving an electrical signal from a force sensitive sensor; comparing the received electrical signal to each of a plurality of reference signal templates; calculating cross-correlation values of the received electrical signal and each of the plurality of reference signal templates; determining a best match reference signal template for the received electrical signal based on the cross-correlation values; identifying a functionality associated with the best match reference signal template; and implementing the identified functionality.
