| Outline of Final Research Achievements |
We have explored tactile displays that improve the sense of presence by spatially reproducing the vibration propagation generated by contact with the body. Specifically, as fundamental research, we conducted physical modeling of high-frequency vibration generation and body propagation of collision motion and vibration propagation characteristics, and perceptual modeling of high-frequency vibration reception characteristics in humans. In addition, by reproducing the vibration of the physical model with multiple oscillators when the stiffness and viscosity were changed, we verified whether the sensation of stiffness and viscosity of the body changed, and confirmed that it could be perceived as the sensation of body material. Furthermore, we have realized a technology for equivalent conversion into signals that can be easily reproduced by small transducers while maintaining the sensation of high-frequency vibrations.
