    摘要: An electronic eyewear device includes a display and a speaker system adapted to present augment reality objects and associated sounds in a scene being viewed by the user. A processor receives one or more audio tracks respectively associated with one or more augmented reality objects, encodes the audio tracks into an aggregated audio track including the audio tracks, a header for each audio track that uniquely identifies each respective audio track, and an aggregate header that identifies the number of tracks in the aggregated audio track. The processor transfers the aggregated audio track to an audio processor that uses the header for each audio track and the aggregate header to separate the audio tracks from the aggregated audio track. The audio processor processes the audio tracks independently in parallel and provides the audio tracks to the speaker system for presentation with the augmented reality objects.

    摘要: A method for managing power resource in an augmented reality (AR) device is described. In one aspect, the method includes configuring a low-power mode to run on a low-power processor of the AR device using a first set of sensor data, and a high-power mode to run on a high-power processor of the AR device using a second set of sensor data, operating, using the low-power processor, a low-power application in the low-power mode based on the first set of sensor data, detecting a request to operate a high-power application at the AR device, in response to detecting the request, activating the second set of sensors of the AR device corresponding to the high-power mode, and operating, using the high-power processor, a high-power application in the high-power mode based on the second set of sensors.

    摘要: A method for a low-power hand-tracking system is described. In one aspect, a method includes polling a proximity sensor of a wearable device to detect a proximity event, the wearable device includes a low-power processor and a high-power processor, in response to detecting the proximity event, operating a low-power hand-tracking application on the low-power processor based on proximity data from the proximity sensor, and ending an operation of the low-power hand-tracking application in response to at least one of: detecting and recognizing a gesture based on the proximity data, detecting without recognizing the gesture based on the proximity data, or detecting a lack of activity from the proximity sensor within a timeout period based on the proximity data.

    摘要: Example systems, devices, media, and methods are described for presenting a virtual experience using the display of an eyewear device in augmented reality. A content delivery application implements and controls the detecting of beacons broadcast from beacon transmitters deployed at fixed locations and determining the current eyewear location based on the detected beacons. The method includes retrieving content and presenting a virtual experience based on the retrieved content, the beacon data, and a user profile. The virtual experience includes playing audio messages, presenting text on the display, playing video segments on the display, and combinations thereof. In addition to wireless detection of beacons, the method includes scanning and decoding a beacon activation code positioned near the beacon transmitter to access a beacon.

    摘要: Disclosed is a of monitoring the breathing of a user, comprising receiving a plurality of audio signals from a plurality of microphones and beamforming the plurality of audio signals into a beamformed audio signal. Observed breath-related parameters are derived from the beamformed audio signal and an output of or derived from the observed breath-related parameters is provided to a user of a client device. Breath metrics may be determined by comparing the observed breath-related parameters with reference breath-related parameters, and a breathing score may be derived from the breath metrics. The breathing score may be based on a combination of how closely an observed respiration of the user matches a prompted or desired respiration rate and an observed amount of time that the user's observed respiration rate is within a threshold value of the prompted or desired respiration rate.
