Improvement of Walking Motivation by Vibratory Display Powered by an Ankle-Worn Generation Device.

We propose an ankle-worn power generation device that supplies power to a vibration speaker to improve walking motivation. With the walking motion of the user, the vibration speaker is driven. In this paper, we propose an interface of a wearable generator that obtains electric power from ankle movement during walking by means of attaching a device with power generation functions to the ankle, and we report the performance evaluation result of the ankle-worn power generation device. In addition, as a part of investigating factors that improve walking motivation, we also describe the results of a questionnaire on walking and its considerations, and the approach to the design-oriented aspects assuming scenarios for future use.
