Indoor navigation plays a crucial role in indoor location-based services. Single signal-based
navigation systems, however, are prone to sensor noises, signal ambiguities and are …

The objective of this work is to develop an indoor location system with high precision and
continuous position monitoring in real time with the use of a mobile phone without any …

We present a fingerprinting-based Wi-Fi indoor positioning method robust against temporal
fluctuations and spatial instability in Wi-Fi signals. An ensemble is created using randomized …

Indoor location-based services rely on the availability of sufficiently accurate positioning in
indoor spaces. A popular approach to positioning relies on so-called radio maps that contain …

Context awareness is crucial for ubiquitous computing, and position is an important aspect
of context. In an ideal world, every stationary object or entity in the built environment would …

In a robotised warehouse, as in any place where robots move autonomously, a major issue
is the localization or detection of human operators during their intervention in the work area …

Camera-equipped mobile devices are encouraging people to take more photos and the
development and growth of social networks is making it increasingly popular to share photos …

We propose and implement a novel positioning system, WalkieLokie, which directly
calculates the relative position from a smart device to a target. The requirement of the target …

The importance of good software testing is often reported. Traditionally, acceptance testing
is the last stage of the testing process before release to the customer. Unfortunately, it is not …

Smartphone localization is essential to a wide spectrum of applications in the era of mobile
computing. The ubiquity of smartphone mobile cameras and surveillance ambient cameras …
