Outline of Final Research Achievements

In this research, we aimed to establish a vibration intensity design method satisfying the proportional scale in three-dimensional shape presentation by vibration stimulation. Based on Weber-Fechner's law, Stevens' power law and other correction terms are combined to construct a vibration intensity design model that suggests that it satisfies the proportional scale.
In addition, we prepared a library for viewing / listening / touching content for information terminals equipped with a touch panel, and implemented a wearable vibration device for this content, thereby improving the experiencing environment of highly versatile three-dimensional contents. Furthermore, we applied the proposed method to the feet and extended the touch experience.
