Abstract:
A communications device providing handset mode operation and speakerphone mode operation, said communications device comprising:a gravitational sensor that senses first and second directions of a gravitational field relative to the communications device in respective first and second orientations of the communications device relative to the gravitational field; and a processor, responsive to the gravitational sensor, that selects speakerphone mode of operation for the communications device when the gravitational sensor senses the first direction of the gravitational field relative to the communications device in the first orientation of the communications device relative to the gravitational field and that selects handset mode of operation for the communications device when the gravitational sensor senses the second direction of the gravitational field relative to the communications device in the second orientation of the communications device relative to the gravitational field, wherein the processor determines that a difference between the first and second orientations of the communications device is greater than a programmable threshold.
