Sensor Fusion (SF) combining accelerometer and gyroscope readings with position sensor (Wi-Fi, GPS) information is the way for increasing indoor positioning precision, mostly during intervals between subsequent callbacks from position sensor. Existing algorithms demonstrate the accuracy acceptable for the users. However customers often require the ALWAYS ON solution implemented on mobile platform...
Indoor location tracking based on wireless sensors such as Wi-Fi and Bluetooth has recently received increased public attention in the context of location-based services (e.g. location-based advertising) and indoor navigation. However, until now, no clear best practices for filters, algorithms and sensor fusion have emerged, and, in fact, different use cases may require different sets of techniques...
Automatic real-time localization of people inside buildings is a huge challenge. For demanding applications in building services, different sensors (e.g. WLAN, RFID, UWB, or ultrasound) are currently used for the real-time indoor positioning. Most systems are only suitable for specific applications or are used under certain conditions, e.g. additional infrastructures and/or sensory mechanisms are...
