Sonovortex

We present a new method of rendering aerial haptics that uses aerodynamic vortex and focused ultrasound. In conventional aerial haptics research, a single physical quantity such as focused ultrasound, aerodynamic vortex, laser induced plasma, or magnetic force and magnet is used to render haptic texture. In contrast, our research combines multiple physical quantities to present multi-resolution tactile feedback. While these fields have no direct interference, our system enables users to feel the tactile feedback of both stimuli simultaneously. We conducted user studies with aerodynamic haptics and ultrasonic haptics separately and tested their superposition perception and resolution. We believe that the results of this study contribute to expanding the expression of aerial haptic displays based on other principles.
