Abstract :
We propose a numerical diagnosis method of a human walk using DCT (discrete cosine transform) of a wearable accelerometer data. We found an apparent difference between smooth walks and non-smooth walks. Our work can contribute to the improvement of people health with a walk diagnosis made by a portable machine.
