| Abstract(in English) | We propose an algorithm that can simultaneously estimate the positions of a user and deployed sensors attached to objects in indoor environments. In order to estimate the positions of user and sensor, we propose user model combined with SLAM (simultaneous location and mapping). The user model estimates the user's position from not only current sensor data but also previously logged data according to reliability factor. The most important advantage of the algorithm is that it requires no calibration. Evaluation results show that estimation errors are less than 320mm in both human and sensors positions, and are small enough to develop context-aware indoor service taking into account the personal space. |
