Patent ID: 8583193

Claim:
A method for adapting a hand-held communication device to include an auxiliary input apparatus, the method comprising the steps of: providing a sensor assembly comprising a plurality of pressure sensors and a plurality of outputs, wherein the sensor assembly is adapted to receive tactile inputs from a user; providing an electrical interface along at least one exterior surface of the device, wherein the electrical interface is adapted for mating with the sensor assembly; attaching the sensor assembly to the at least one exterior surface of the device, such that the outputs of the sensor assembly are electrically coupled to the electrical interface; and performing an assignment procedure wherein specific tactile inputs to the sensor assembly are assigned to specific predefined functions of the device, such that the device is operable to perform each of the specific predefined functions in response to specific tactile inputs being applied to the sensor assembly; wherein the hand-held communication device is a cellular telephone; and wherein the specific predefined functions of the device include at least one of: a speed-dial function, wherein the cellular telephone dials a pre-assigned telephone number in response to a specific tactile input; a phone directory review function, wherein the cellular telephone audibly announces a list of stored names in response to a specific tactile input; a combined phone directory review and speed-dial function, wherein: (i) in response to a first specific tactile input, the cellular telephone audibly announces a list of stored names; and (ii) in response to a second specific tactile input that is received while the telephone is audibly announcing the list of stored names, the cellular telephone speed-dials a telephone number corresponding to the last stored name that has been audibly announced at the time when the second specific tactile input is received; and an expedited menu access function, wherein the cellular telephone displays a pre-assigned screen menu in response to a specific tactile input.
