Abstract :
We discuss the feasibility of a new tactile display using acoustic radiation pressure. We confirmed the prototype system produced 1 mm diameter focal point and 0.64 gf total force. Temporal property of radiation pressure was sufficient for precise tactile stimulations. We also propose a method for scanning radiation pressure in 2-dimensional plane using a simple apparatus.
