A Strategy for the Use of Indoor and Outdoor Augmented Reality Location Systems Applied to Smartphones

The use of location systems has become commonplace in our day. However, there are major limitations when it comes to localization indoors. This work proposes an architecture that allows location data integrity when the user moves from an external environment to an internal one. Using sensory hardware integrated to smartphones, the proposed system allows the exchange of information about the location of the participants of a network of contacts. For this purpose, a digital map, associated with Augmented Reality techniques, displays the position of these people, regardless the space they are in (external or internal). To compensate for the incremental errors inherent in the estimated navigation systems, a time series treatment algorithm, known as Dynamic Time Warping (DTW), is used. Thus, the suggested solution can be implemented without the need to install a supplementary infrastructure in the environment, especially when indoor navigation is required.
