Determining user location with remote controller

摘要

An audio device may be configured to work in conjunction with a handheld remote controller to receive voice commands from a user. The audio device may have multiple local microphones that are used for sound source localization, to determine the position of the user. A remote audio signal may be received from the remote controller and used in conjunction with local microphone signals generated by the local microphones to aid in determining the position of the user. The last known position of the user may be recorded whenever the user speaks into the remote controller. When the user is unable to find the remote controller, the audio device may direct the user toward the last known position of the user.

主权项

1. A device comprising:
a communications interface configured to receive a remote audio signal from a remote controller that is held and spoken into by a user, wherein the remote audio signal represents speech of the user; an array of microphones configured to produce multiple local audio signals representing the speech of the user, wherein the microphones of the array have a fixed spatial arrangement within the device, and wherein the remote controller is at a variable position relative to the device; a sound source localization service configured to analyze the local audio signals and the remote audio signal to determine one or more positional coordinates corresponding to a position of the user relative to the device when the user speaks into the remote controller; a tracking service configured to record the one or more positional coordinates as an indication of a last determined location of the remote controller relative to the device; and a notification service configured to provide information to the user regarding the last determined location of the remote controller based at least in part on the one or more positional coordinates.
