WSN based 3D Mobile Indoor Multiple User Tracking

This paper presents the integration of immerse 3D graphics contents as the representative of guidance information in real-time indoor environment. The designed system enables the tracking of nearby targets by utilizing the exact same system within the wireless sensor network sensing range. During the tour, union of 2D and 3D graphics provide even clearer path navigation while supporting textual information service to the targets, synchronized their location with real physical indoor scenes. Target's orientation is determined by applying digital magnetic compass (DMC) to the system corresponding to target current perspective view. Received Signal Strength Indicator (RSSI) model performs low-cost indoor tracking system by increasing its position precision with compliant refinement algorithm. Introduction of context information service manages to give some overviews for certain places (rooms, toilet).
