We present a comparative analysis of inertial-based odometry algorithms for the purpose of assisted return. An assisted return system facilitates backtracking of a path previously taken, and can be particularly useful for blind pedestrian. We compared the path reconstruction accuracy of a stete of the art odometry system based on deep learning (RoNIN) against a system based on robust turn detection and step counting, using data from WeAllWalk, the only data set with inertial data recorded from blind walkers. In addition, we tested a new algorithm for path matching in simulated assisted return tasks with data from WeAllWalk.
