Walk analysis is enabled to use wearable gait analysis system without choosing the measurement range and the place. However an error is included in the output of the sensor. A shocking acceleration to occur at the moment when a heel grounds during a walk has a large influence on the attitude angle estimate of the heel. This result leads to a decrease in the precision of walk analysis. Therefore this study is suggested a method to control the decrease in the precision of the attitude angle estimate of the heel. First, when a heel grounded, we use an integral of the gyro sensor that there is little influence of the shocking acceleration. Second, the angle of the heel is corrected to 0 degrees at the foot flat. Finally, the error by a phase gap is compensated using a logarithmic function. The proposed method improves the precision of a heel attitude angle estimate in the walking.
