25. Outdoor Experiment Setting Participants are asked to walk around the ring region in the NCKU campus. Examiner will walk with them and ask them the direction of the starting point in five fixed point on the way. During a straight path of forty meters, participants will wear non-invasive sensors to measure the gait information.
