    Abstract: Techniques are described for improving driver efficiency. An example method can include a device accessing sparse location data indicative of one or more geographic locations along a route of the user device during a first time period. The route includes a starting location data point and an ending location data point. The device can access motion data collected by the sensors of the user device. The motion data can be collected by the sensors during the first time period. After a conclusion of the first time period, the device can generate, using the sparse location data and the motion data, a dense data set to reconstruct a route that includes the starting location data point and the ending location data point. The reconstructed route can include second dense location data and velocity data. The device can store the reconstructed route in a local memory of the user device.

    IPC: H04W4/029

    Abstract: A device implementing a system for estimating device location includes at least one processor configured to estimate a first position of a device based on a first set of parameters, the first set of parameters derived from first sensor data obtained on the device, the first set of parameters corresponding to device motion. The at least one processor is configured to estimate a second position of a user of the device based on a second set of parameters, the second set of parameters derived from second sensor data obtained on the device, the second set of parameters corresponding to user motion. Estimating the first and second positions is constrained by a predefined relationship between the device motion and the user motion. The at least one processor is configured to provide at least one of the first position of the device or the second position of the user.

    IPC: G01C21/30

    Abstract: The subject technology provides for visualizing a route traversed by a user during a movement event by periodically obtaining position information data from a receiver of a navigation system during a movement event. A path traversed by a user of a device that includes the receiver during the movement event is estimated based on the position information data. One or more previously mapped features within a proximity of the estimated path on a map are determined. The estimated path is matched to the map based on the previously mapped features to obtain a map-matched path. A display device is caused to render the map-matched path on an image of the map.

    Abstract: Techniques are described herein for low-power pedestrian route reconstruction. A method can include accessing location data comprising a set of location points collected by a user device during a workout and defining an initial route. The method can further include accessing map data comprising a plurality of paths within a geographic region. The method can further include, for a plurality of location point pairs of the set of location points, determining a route segment between the pair of location points that follows a path segment of the plurality of paths. The method can further include combining route segments for each location point pair of the plurality of location point pairs to define a reconstructed route that begins with a first location route pair based on an initial location point and ends with a second location route pair based on a final location point.
