Abstract:
A method for controlling the orientation of a virtual microphone, which is carried out on an electronic device, includes combining and processing signals from a microphone array to create a virtual microphone; receiving data from a sensor of the electronic device; determining, based on the received data, a mode in which the electronic device is being used; and based on the determined mode, directionally orienting the virtual microphone. Possible use modes include a) a stowed use mode, in which the criterion is the electronic device being substantially enclosed by surrounding material; b) a handset (alternately, private) use mode, in which the criterion is the electronic device being held proximate to a user; and c) a handheld (alternately, speakerphone) use mode, in which the criterion is the electronic device being held away from a user.
