Methods for controlling a hand-held electronic device and hand-held electronic device utilizing the same

摘要

A hand-held electronic device. A sensing surface is adapted to detect fingerprints and a contact of an object on the sensing surface. Storage stores a fingerprint signature. A controller is configured to determine whether a composition of detected fingerprints matches with the fingerprint signature and determine at least one character of the contact. The at least one character comprises a location on which the object contacts the sensing surface.
