Path Guide is a completely map-free, infrastructure-free, plug-and-play indoor navigation service. It exploits the ubiquitous geomagnetism and natural walking patterns to guide users to destinations along a path collected by an earlier traveler. There are three simple steps to start using Path Guide.
- User records sensory data with his/her device during a given indoor walk. The location-specific geomagnetic features extracted from the sensory data are combined with the user’s walking patterns (e.g., steps, turns, going upstairs/downstairs) to build a reference trace.
- Reference trace is pushed to the cloud and can be searched by others for navigation.
- Once downloaded a reference trace, Path Guide compares and synchronizes current sensor readings with the reference trace, and guides the user, in real time, from the same starting location to the final destination.
