For comprehensive quantitative estimation of falling injury risks, it is important to divide the injured time into fall trigger, protective reaction, and passive deformation of body tissue. However, the mechanism of fall trigger has not been clear. Therefore, we constructed fall trigger detection method based on analysis of some falls of infants captured in living environments. In analysis, we acquired fall motion data by using a motion capture system, and evaluated fall trigger using Center Of Pressure on BOS coordinates and foot angle (Roll, Pitch, and Yaw). As specific changes of time courses of the parameters were observed near the fall start time, these parameters can be related to fall trigger. In addition, we detected the fall trigger using the change point detection in falls by the sliding. As a result, we detected fall trigger all three falls by the sliding. The method is useful for the detection of the fall trigger in the fall by the sliding.
