Abstract Indoor Location Based Services (LBS), such as indoor navigation and tracking, still
have to deal with both technical and non-technical challenges. For this reason, they have …

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 …

Microelectromechanical Systems (MEMS) technology is playing a key role in the design of
the new generation of smartphones. Thanks to their reduced size, reduced power …

This paper presents a method for pedestrian activity classification and gait analysis based
on the microelectromechanical-systems inertial measurement unit (IMU). The work targets …

Low-cost MEMS-based IMUs, video cameras and portable GNSS devices are commercially
available for automotive applications and some manufacturers have already integrated such …

Indoor pedestrian navigation systems are increasingly needed in various types of
applications. However, such systems are still face many challenges. In addition to being …

Context-awareness is an interesting topic in mobile navigation scenarios where the context
of the application is highly dynamic. Using context-aware computing, navigation services …

Dilution of precision (DOP) is a value that can describe the effect on the relationship
between measurement error and position determination error. The DOP of a positioning …

In this paper, a motion estimation approach is introduced for a vision-aided inertial
navigation system. The system consists of a ground-facing monocular camera mounted on …

In this paper, we investigate how self-contained pedestrian navigation can be augmented by
the use of foot-to-foot visual observations. The main contribution is a measurement model …
