How to find the location of a person indoor ?

kf

Hi,

I would like to know if it's possible to find the exact location, of a person in close area ( indoor ).

assuming that person has a smartphone in his hand ( and all the hardware is available : Compass, Gyroscope , Accelerometer , GPS, WiFi etc. ).

Thanks

Marc

It is possible, but not trivial. See here:

They seem to be doing it at the Art Institute of Chicago, but there is no explanation of how it works... :) http://www.artic.edu/visit/maps-guides-and-apps
