Abstract

We propose a shoe-shaped interface designed to induce a specific walking cycle, and investigate stimulation techniques for effective induction of the walking cycle. The proposed interface is useful for walking navigation system, which enables the wearer's locomotion without paying attention to surrounding circumstances. The interface consists of a vibration motor for stimulation and pressure sensors for measuring walking cycle. Using sensory-motor synchronization of human body, this interface can induce a walking cycle effectively without mechanical constraint. The results of our experiments indicate that vibration stimuli at heel grounding timing enable effective induction and that wearers can smoothly shift their walking cycles to the indicated cycle, if the shift of the stimulation cycle is within the range of -100 and +150 ms from their walking cycle.
