This paper presents a method for estimating the movement of a user using a system that combines GPS, a microphone and an acceleration sensor able to be fitted in a mobile phone. Past attempts to provide a means to identify movement associated with riding on a bicycle, train, bus or car, in addition to common human movements like standing still, walking or running, have had problems with poor accuracy due to factors such as sudden changes in vibration or times when the vibrations resembled those for other types of movement. The proposed method aims to avoid these problems by treating time-axis changes in the data from each sensor as state transitions, and by combining different techniques for identifying each type of movement. Performance test results show that the method achieves 80% or better accuracy for all seven of the different types of movement mentioned above. |
