Implementations of the subject technology provide for audio integration of portable electronic devices into enclosed environments. A portable electronic device may be carried, by a user, into an enclosed environment, such as into an enclosure of a building, a room, or other apparatus. One or more remote speakers may be disposed in the enclosed environment. The remote speaker(s) may be operated in cooperation with the portable electronic device to spatially coordinate audio output from the remote speaker(s) with video content displayed by the portable electronic device.

Methods, systems, and media for identifying a plurality of sets of coordinates for a plurality of devices are provided. In some embodiments, the method comprises: identifying each device in a plurality of devices associated with a user account; instructing the plurality of devices to perform an audio sequence; receiving a plurality of transit times from the plurality of devices; determining a plurality of distances based on the plurality of transit times; determining a plurality of sets of coordinates based on the plurality of distances; associating to each of the plurality of devices a corresponding unique one of the plurality of sets of coordinates; and causing at least one of the plurality of devices to play spatial audio determined from the plurality of sets of coordinates.

Implementations of the subject technology provide occupant-based audio for enclosed environments. For example, an apparatus having an enclosure and one or more speakers may determine a location and/or an identity of an occupant within an enclosed environment defined by the enclosure, and operate the one or more speakers to provide audio output to the location of the occupant. The apparatus may also operate the one or more speakers to reduce the audio output to one or more other locations within the enclosure, such as to one or more non-occupant locations and/or to one or more locations of one or more other occupants. The audio output may be occupant-specific audio output, such as a personalized notifications, in one or more implementations.

Systems and methods for media playback via a media playback system include detecting a first wake word via a first network microphone device of a first playback device, detecting a second wake word via a second network microphone device of a second playback device, and forming a bonded zone that includes the first playback device and the second playback device. In response to detecting the first wake word, a first voice first voice utterance following the first wake word is transmitted a first voice assistant service. In response to detecting the second wake word, a second voice utterance following the second wake word is transmitted to a second voice assistant service. Requested media content received from the first and/or second voice assistant service is played back via the first playback device and the second playback device in synchrony with one another.

A system and method for conducting a refractive examination of an eye of a patient, has a communication device with a communication module that connects to the internet, a processor that is programmed to connect to a remote computer via the communication module and which has a display screen, a microphone and a speaker. The remote computer has a data storage device that stores images of eye charts. The communication device is mounted in a virtual reality headset configured to be worn by the patient and has at least one screen through which the display screen of the communication device is viewable. The communication device displays images in the form of the eye charts to the patient, who communicates through the communication to a remote examiner who conducts the refractive examination using multiple different eye charts to determine the prescription of the patient.

Systems and methods for localizing portable devices are illustrated. One embodiment includes a method for locating a portable device in a network that includes several reference devices. The method measures characteristics of signals transmitted via signal paths between reference devices and a portable device, normalizes the measurements to estimate characteristics of the signal paths, and estimates the likelihood that the portable device is in a particular location. Systems and methods for training prediction models include a method that includes steps for receiving context data for a portable device in a system, wherein the context data includes localization data that describes a location of the portable device, identifying a predicted stationary device based on the context data using a prediction model, identifying a target stationary device from the several stationary devices, training the prediction model based on based on the predicted stationary device and the received input.

A live data distribution method obtains information on a sound source according to sound generated at the first venue, and information on space reverberation, as distribution data, distributes the distribution data to the second venue, and renders the distribution data and providing sound according to the distribution data at the second venue.
