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.

Abstract: A mobile device may determine a set of range values between the first mobile device and the second mobile device based on a difference between the first time and the second time for ranging wireless signals. The mobile device can determine first odometry information using a first sensor on the first mobile device, the first odometry information indicating a first motion of the first mobile device during a time period. The mobile device can receive, via a data channel, second odometry information determined from second measurements captured using a second sensor on the second mobile device. The mobile device can solve an angle between a first reference frame for the first device and a second reference frame for the second device using the set of range values, and the first and second odometry information to display a directional arrow pointing to a current position of the second mobile device.
