Recently, indoor navigation on mobile devices has received attention from both startups and large vendors, since it has many relevant practical and commercial applications. User positioning and navigation using GPS signals is becoming more and more popular, mainly due to the increasing availability of acceptable quality sensors into low-cost consumer devices as smartphones. However, indoor GPS-navigation is highly unreliable because of the poor communication with satellites and the lack of detailed maps. In this paper we discuss the technologies allowing the indoor computation of accurate location and orientation data, as well as other issues and challenges that indoor navigation apps should cope with. In particular, we present and make explicit reference to a system for indoor navigation (running on a smartphone), which has been designed by the Authors, including the main problems that have been tackled during its implementation. The paper is and will be complemented by some explanatory videos.
