An efficient tool for indoor user location based on QR-Codes and Google maps

Abstract
An increasing number of new geolocation services are exploiting the new capabilities of smartphones, most of which incorporate GPS location. There are fewer applications for providing indoor location, partly due to the cost of the required infrastructure. In this paper, we present QR-Maps, a simple and efficient tool that can be used in smartphones to obtain accurate indoor user locations. This tool employs QR-Codes containing a short text which indicates locations shown within a custom Google map. The proposed solution is cheaper than other approaches based on wireless technologies.
