Outline of Final Research Achievements

In this study, we propose methods that stimulate the skin surface from the outside to induce specific behavior, and verified their performances. We proposed two methods. One is to induce flexion movement of the elbow joint by presenting shear deformation to the forearm. The other one is to use the gyroscopic effect to make user’s wrist rotate. By attaching rotating disks to the wrist, the force is given when the arm swings perpendicular to the rotational axis.
As we implemented these methods, there was a tendency to continue behavior against the external stimuli especially when the behavior is unconsciously performed by people like walking. Therefore, we also developed a system for real-time prediction of human motion so that stimulus can be presented at an appropriate timing during such motions.
