Development of an app for indoor navigation assistance

Abstract

In outdoor environments, the user's navigation aid can be provided by using signals received from GNSS (Global Navigation Satellite System) satellites or by GSM (Global System for Mobile Communication). Inside the buildings the use of these technologies is not possible, therefore is necessary the use of other positioning methods to assist the user. One of the solutions for positioning in this environment is the WIFI technology, which is implemented in mobile devices such as smartphones. However, there are not yet many solutions that can be adopted in indoor environments that can help the user's positioning. In this research was developed an application on the Android platform, using the techniques of centroid, centroid weighted and trilateration, to provide the positioning forthe indoor environment, to be later presented on a map with the purpose of assisting the navigationof the user in the indoor environment. The application allows the user to identify his position in the environment from the interaction with the map. Besides that, is presented a position marker, indicating the floor and building where the user is, which guides the user in a better way, allowing his localization and creating a tool suitable for this type of environment. This research is part of the UFPR CampusMap project of the Federal University of Parana.
