저가형 관성 측정 장치를 이용한 실내 측위 시스템 구현

Location information is important in ubiquitous computing system. In this paper, we implemented indoor positioning system using low cost inertial measurement unit. The system can collect acceleration information from 3-axis accelerometer and angle information from gyroscope. Also, the system calculates distance and direction from collected data. The system provide spatiotemporal graphical user interface.
