Abstract: Techniques are described for reconciling events timestamped in different time domains in multi-node systems supporting low-latency hardware timestamping. First and second nodes having independent time bases are synchronized by the first node generating an event that is received effectively simultaneously at the first and second nodes, the first and second nodes recording a timestamp of receipt of the event, the first node asynchronously querying the second node for its timestamp of receipt of the event and comparing its timestamp of receipt of the event with the timestamp of receipt of the event by the second node, and the first node using a difference in the timestamps of receipt of the event by the first and second nodes to align the time bases of the first and second nodes. The nodes may include hardware timestamping functionality or use an external component (e.g., field programmable gate array) to provide the timestamping functionality.

Abstract: 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.

Abstract: 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.
