The accident which the person inverts while walking is problem. For example, lower limbs are easy to slip because of any kind of state at walk time, The detection of starting to invert is important. We focus on the walking motion cycle the double support phase, the swing leg phase and the stance phase. The focus is applied to middle swing leg phase especially. The walking data was acquisitioned with triaxial accelerometer sensor. We discussed the relations the inversion and the state of swing leg.
