In a large-scale perceptive environment, where users are placed at the center, user identification and localization play essential roles. Location information is an important tool for enabling multiple applications, e.g., community settlement planning, traveling, mining, surveillance, monitoring, military applications, and nowadays the development of location-based services (LBS) and engineering. Localization techniques have been actively studied recently due to service as well as safety and security matters.

 

 

This platform uses the localization as a core feature as an important portion of pervasive applications are location based. Localization technologies which are different in nature are integrated: WiFi, camera (fix/mobile, analog/digital), GPS, RFID, step count… and multimodal approach which consist in combination of multiple technologies to increase accuracy and cover range.
