Recently launched smart watches have a built-in pressure sensor that can measure the slope or altitude, so it can measure user momentum. In addition, the magnetometer sensor can measure the earth's magnetic field to know the exact orientation and measure the direction of movement. In addition, various sensors can be used to trace the location of a user wearing a smart watch. In this paper, the trajectory path pattern recognition model based on HMM (Hidden Markov chain Model) is proposed. It traces the user's trajectory using a smart watch, a kind of wearable device in the room where GPS (Global Positioning System) cannot be used. |
