Path Guide – Plug-and-play indoor navigation service

App Name: Path Guide [Android App]
Cost: Free (No ads)
Publisher : Microsoft Corporation
Description :

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.

  • 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.
