ABSTRACT
Reproducing the tactile texture of a real object allows humans to interact in virtual reality space with a high sense of immersion. In this study, we develop a midair haptic-optic display with multi-tactile texture using focused ultrasound. In this system, users can touch aerial 3D images with a realistic texture without wearing any devices. For rendering realistic texture, our system simultaneously presents vibration and static pressure sensation. The presentable sensation of the previous ultrasound system is limited to vibrations. The combination of the sensations can improve the reality of rendered tactile texture by ultrasound. In the demo, we presented three textures with different roughness: cloth, wooden board, and gel.
