| Outline of Final Research Achievements |
An active touch that gets a tactile sense by touching and moving an object gives various clues about the target.
In this research, we aim to compute and present deformation and vibration by physical simulation to realize virtual reality, where the user perceive internal structure and material by active touch. We worked on (1) a short computation time deformation algorithm and (2) reproducing of vibrations generated by active touch.
For (1), we proposed a method to reduce computation time by decomposing the target into local groups and using the local stiffness matrix. For (2), we show that an accurate friction coefficient model for stick-slip friction reproduces stick-slips close to reality and it improves the feel of reality.
