  • Patent number: 10237666
    Abstract: An electronic device includes a housing and a user interface. The electronic device also includes an acoustic detector and one or more processors operable with the acoustic detector. The one or more processors can receive, from the user interface, user input corresponding to an operation of the electronic device. The one or more processors can then optionally initiate a timer in response to receiving the user input and monitor the acoustic detector for a predefined acoustic marker, one example of which is acoustic data indicating detection of one or more finger snaps. Where the one or more finger snaps occur prior to expiration of the timer, the one or more processors can perform the operation of the electronic device. Otherwise ignore the user input. The acoustic confirmation of user input helps to eliminate false triggers, thereby conserving battery power and extending run time.
