Abstract: Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. One embodiment involves pairing a client device with a wearable device, capturing a first client location fix at a first time using the first application and location circuitry of the client device. The client device then receives content from the wearable device, where the content is associated with a content capture time and location state data. The client device then updates a location based on the available data to reconcile the different sets of location data. In some embodiments, additional sensor data, such as data from an accelerometer, is used is used to determine which location data is more accurate for certain content.

Abstract: Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

Abstract: A neural network system includes an eyewear device. The eyewear device has a movement tracker, such as an accelerometer, gyroscope, or an inertial measurement unit for measuring acceleration and rotation. The neural network system tracks, via the movement tracker, movement of the eyewear device from at least one finger contact inputted from a user on an input surface. The neural network system identifies a finger gesture by detecting at least one detected touch event based on variation of the tracked movement of the eyewear device over a time period. The neural network system adjusts the image presented on the image display of the eyewear device based on the identified finger gesture. The neural network system can also detect whether the user is wearing the eyewear device and identify an activity of the user wearing the eyewear device based on the variation of the tracked movement over the time period.
