| Outline of Final Research Achievements |
The present study realizes a wearable haptic display by selectively presenting force by skin deformation, force by electrical stimulation to tendons and muscles, and displacement by tendon vibration stimulation. In force presentation using skin deformation, we found that simple shear deformation can provide efficient force presentation. In the presentation of motion illusion using electrical stimulation, we investigated electrical stimulation of both tendons and muscles, and found that stimulation of finger tendons produces force sensation, and that electrical stimulation of finger muscles from the instep can present force in the direction of adduction. In the case of muscle spindle stimulation by tendon vibration, we demonstrated that simultaneous stimulation of many tendons involved in the movement enhances the amount of illusion and that tendon vibration during the movement produces the perception of a change in the physical properties of the grasped object.
