Pedestrian dead reckoning enables pervasive indoor localization without a site survey on
fingerprints or an intensive deployment of infrastructures. But accumulated errors in dead …

Recently, we have witnessed a booming growth of Wi-Fi-based indoor localization systems
that can locate the user without requiring the user to hold or wear any device. To foster a …

The lack of floorplan limits the spread of pervasive indoor location-based services. Existing
crowdsourcing based approaches mostly rely on identifying, locating landmarks in the …

The quality of location information is an important factor for location-based services (LBSs).
In the literature, the quality of location information has been defined in different ways based …

Geomagnetic field is highly applicable to indoor localization due to its pervasive spatial
presence, high signal stability and infrastructure-less support. Previous work in the area …

Indoor localization is of great importance in the era of mobile computing. Smartphone-based
pedestrian tracking is essential to a wide range of applications in shopping malls, industries …

In this paper, we propose and implement WalkieLokie, a novel acoustic-based relative
positioning system. WalkieLokie facilitates a multitude of Augmented Reality (AR) …

We present Follow-My-Lead, an alternative indoor navigation technique that uses visual
information recorded on an actual navigation path as a navigational guide. Its design …

In this article, we propose a new indoor positioning algorithm using smartphones, where
wireless signals and images are deeply combined together to improve the positioning …

In recent years, indoor positioning technology has been a hot spot, especially Bluetooth Low
Energy (BLE)–based fingerprint positioning because it can be implemented on smart …
