| Research Abstract |
We use not only visual information but also haptic information such as touch feeling of textile fabrics. So it is needed to give haptic information to clients to feel more 'realistic' sensation. In museums, we usually 'watch' exhibits. It is very rare to 'touch' exhibits, although touching is very good opportunity to feel and learn from the exhibits. And people can get more realistic impression from them. Future robotic teleoperation as dexterous as human hand requires display of multi-modal sensations on the master side for human operators, such as vision and tactile sense. Especially, for precise tasks, technology to display subtle difference of object touch is important.In the area of human computer interaction, technology to display very complex tactile feeling is very effective to express information from computers. In these points of view, making artificial tactile feeling technology is very important.
In this research, we developed artificial tactile feel display using soft high polymer gel actuators (ICPF). This tactile display can generate very complex tactile feeling such as textile fabrics. Recently, many types of haptic devices have been investigated. These haptic devices make it possible to touch objects in a virtual environment, and most of them are only 'force' feedback devices such as PHANTOM. There are few devices which can display tactile sensation including 'quantitative' information to human skin.
Then, the artificial tactile feeling stimulus generated by this actuator were evaluated by the experiments. Moreover, cerebral somatosensory area activated by the tactile feeling stimulus were analyzed by f-MRI. We are under consideration about tactile feeling cognition and comfortableness based on our experimental results by Genetic Algorithm and Evolutionary Learning methods.
