| Outline of Final Research Achievements |
This research aimed to realize a tactile display that changes surface friction remotely using ultrasound phased array, and to elucidate its basic characteristics. Before starting this project, it was confirmed that the friction on the polystyrene foam surface was reduced by using the ultrasound focus. This research has made progress in this field by taking the following three approaches: 1) clarification of the phenomenon of friction reduction on the surface of polystyrene foam, 2) realization of a friction-changing interactive system using polystyrene foam, and 3) investigation of friction reduction on surfaces other than polystyrene foam using an appropriate resonant structure.
We proposed a new concept of a "disposable tactile display" because the device does not need to be mounted on the target surface.
