PROBLEM TO BE SOLVED: To provide a system useful for predicting a user's tripping to prevent the user from tripping during the user's walking.SOLUTION: A tripping prediction detection system 11 comprises leg data acquisition means 14 for acquiring user's leg movement data during walking, and tripping provability determination means 15 for determining the user's tripping provability at a step located in front of the user on the basis of the leg data acquired by the leg data acquisition means 14. The leg data acquisition means 14 measures the height of the user's knee joint and a thigh-raising angular velocity of the user's thigh when the user raises his or her thigh as leg data. The tripping provability determination means 15 determines the user's tripping provability at the step on the basis of the leg data acquired at a determination point located before the step at a predetermined distance from the step and step information of the step. |
