lapillus bug : Creature-like Behaving Particles Based on Mid-Air Acoustic Manipulation and Interaction with them

Abstract

Modern technology development has made the border between life and matter more ambiguous. In this research, we aim to extract and express creature-like behavior from inanimate objects. By generating a standing wave with focused ultrasound, a phenomenon known as acoustic levitation enables a physical particle to float in mid-air. The particle is trapped in the ultrasonic focal point and follows its position. We have developed a system where users can interact with the floating particle that looks and behaves as though it is a small hovering bug. We have received many reactions and opinions from attendees at exhibitions. In this paper, we describe the system overview, concept, design, implementation, and feedbacks from the exhibitions.
