HORN

Interaction with mid-air floating virtual objects expands human-computer interface possibilities. Here, we propose a system that superimposes haptic volumetric sensations on mid-air floating images by using acoustic potential distribution.

Our surrounding phased-array system freely produces 3D spatial patterns of ultrasonic standing waves, which create various feelings of elastic and textured surfaces. The ultrasound does not affect the optical images and can be controlled quickly in this interactive system. The combination of 3D volumetric vision and this haptic technology flexibly displays the presence of 3D objects that can be pinched, handled, and manipulated.
