Performance evaluation of sensing vest for feeling object behind person in normal direction of skin surface by haptic sense of back

Abstract

A ranging and vibrator module and a sensing vest composed of the module were made. A condition of contact with a vibration plane and the skin surface was checked by a person in the made sensing vest. The frequency of the vibration was measured using the person in the made sensing vest. The vibration or non-vibration of the module was checked at an object behind the person by the person in the made sensing vest. The results have shown the usefulness in the sensing vest for feeling the presence or absence of the object behind the person in the normal direction of the skin surface by haptic sense of back.
