Augmentation of thermal sensation on finger pad using stimuli for finger side

Abstract

This paper proposes a thermal display that can present a virtual thermal sensation to the finger pad using thermal stimuli on the finger side. The author developed the prototype device and evaluated the perceived strength of the thermal sensation on the finger pad after the pad makes contacts with an object. The results confirm that users perceive hot or cold sensation even if there are no thermal stimuli on the finger pad by presenting stimuli to the finger side. Furthermore, the proposed method successfully improves thermal sensation by applying the same thermal stimuli to the finger side as the sensation on the finger pad.
