Abstract:
Various embodiments of the present invention relate to providing an audible route sequence for guiding a user along a route. A user apparatus determines a user location, distance and directional aspects for one or more waypoint of the route, and a cadence. A distance aspect of a waypoint is a distance between the waypoint and the user location. A directional aspect of a waypoint is the angle between a reference heading and straight line connecting the waypoint to the user location. The cadence is determined based on the distance between consecutive waypoints. The user apparatus determines a route sequence based on the distance and directional aspects for the waypoints and the cadence. The route sequence comprises a sequence of audible pitches that each correspond to a waypoint of the route. The user apparatus causes the route sequence to be audibly provided via a sound device.
