| Research Abstract |
In this research, we developed an interaction system in electromagnetic virtual space using 3D tactile sensor. The following systems and algorithms have been developed.
(1)Development of an interaction system with information distributed in 3D electromagnetic virtual space by using 3D tactile sensor : At first, we developed a receiving system of electromagnetic force that is acting to a core setting in 2D virtual electromagnetic field. By moving the core in the virtual space, observers can feel the electromagnetic force acting the core. In the second step, we developed the 2D system to 3D system, and we developed an algorithm drawing stereoscopic images.
(2)Development of an automatic hexahedral mesh generation method to control shape of elements : Ellipsoidal Bubbles are employed as mesh density data. By utilizing Ellipsoidal Bubbles, the mesh size can be controlled along each direction adequately, and flat elements can be generated.
(3)Developments of an error evaluation scheme based on magnetic field intensity in adaptive finite element analysis : We propose a new error evaluation method based on the rotation of the intensity of magnetic filed obtained from the results of finite element method with coarser mesh. The newly proposed method has no complicated process on the interface between the different materials.
