Abstract

We propose a local positioning system that tracks human's movement. The system uses two 3-axis accelerometers mounted at the human's feet to detect steps. An electronic compass is used to obtain an absolute heading. Both step and heading data are combined to plot a movement trajectory on a building floor map based on the dead reckoning method. The system is tested by tracking a closed-loop walking trajectory: starting from a room, walking to another room about 20 meters away, and walk back to the starting point in the first room. The result shows about 2 meters accumulated error from the starting point.
