Design and evaluation of vortex air cannon for air pressured facial tactile

Abstract

We propose vortex air cannon system for novel tactile display mainly used for attraction. We call this system as facial tactile display. In this paper, we clarify vortex air canon has potential to use for tactile expression by conducting two-point threshold experiment on facial surface. Then as a pilot study for facial tactile display, a piston and valve type of vortex air canon system are developed. And by controlling tactile strength using the theory of vortex ring, we evaluate hit probability toward a target and realized various speed control for multiple tactile expressions.
