How can I track indoor locations? [closed]

Question

I'm doing a project which needs to track location indoors. It needs to track where someone is inside a building and show them where to go. I've read quite a lot on the subject for all three main smartphone OS's (iOS, Android and Windows Mobile). I would prefer to do it on Windows Mobile if possible to start with as it is the system I can work with the best.

I have decided I'm primarily going to use QR codes to "reset" the position (i.e., have reset points throughout the building where people can stand, scan, and it gets their current location). How can I then track movement away from this point of origin?

Answer 1

As far as I know, the only solution for you is to use indoor location fingerprinting. Essentially, you need to map signal strengths on locations for the positions that are known. Whenever a mobile phone is on that location, it should read similar signal strengths from various WiFi antennas. When this reading is compared to fingerprints of the indoor locations, the best match should be the location. Different algorithms can be applied.
