Pedestrian navigation using inertial sensors constitutes an infrastructure-free positioning
system. The fact that inertial sensors are already available in every smartphone or other …

This paper proposes a pedestrian dead reckoning (PDR) algorithm based on the strap-down
inertial navigation system (SINS) using the gyros, accelerometers, and magnetometers on …

Every year, for ten years now, the IPIN competition has aimed at evaluating real-world
indoor localisation systems by testing them in a realistic environment, with realistic …

In recent years, we have assisted with an impressive advance in augmented reality systems
and computer vision algorithms, based on image processing and artificial intelligence …

In this paper, we present a system that allows visually impaired people to autonomously
navigate in an unknown indoor and outdoor environment. The system, explicitly designed for …

In recent years, indoor localization systems have been the object of significant research
activity and of growing interest for their great expected social impact and their impressive …

Acquiring accurate and reliable pedestrian trajectories is essential for providing indoor
location-based services. Although a foot-mounted inertial navigation system (Foot-INS) can …

Some of the researches on indoor positioning have been conducted, but there are still many
constraints on indoor positioning approaches. Among these approaches, ultra-wideband …

Accurate heading estimation using low-cost sensors becomes an important task in
pedestrian dead-reckoning (PDR). The challenges of heading estimation come from three …
