The airflow that accompanies the tactile sensation provided by the Airborne Ultrasound Tactile Display is investigated. Due to it, some people say that they feel something like airflow although the display generates steady pressure in air. We have two ideas what causes it: One is the gradient of pressure distribution and the other is the acoustic streaming. In this paper, experiments are conducted to observe the phenomenon arises around the ultrasound beam. The airflow is visualized with smoke and also its spatial distribution is measured with a pressure sensor. As far as the results, the idea of the acoustic streaming is supported.
