Performance Evaluation of Indoor Positioning Systems based on Smartphone and Wearable Device

Recently, most solutions designed for Ambient Assisting Living systems are based on indoor positioning systems. There are several technologies and approaches to develop indoor tracking and positioning with different advantages and shortcomings. Taking into account as a starting point some limits and issues analyzed in related scientific works focused on smart AAL systems able to improve the life quality of elderly people, this work aims to carry out a performance comparison between two different approaches to track a person in indoor environments. Both a smartphone and a wearable device have been used in our tests, analyzing the differences of each approach.
