What is it about?
DAWBeads is a system that uses ultrasonic levitation arrays to visualize rhythms using floating beads as a metaphor for musical elements and to combine sounds by manipulating the beads. DAWBeads allows users to manipulate sounds intuitively in 3D space, even without knowledge of music. Specifically, it realizes a DAW (Digital Audio Workstation) system for amateurs to combine sounds or change pitches.

Why is it important?
DAWBeads consists of two points technical elements. The first is interaction acquisition. By tracking the hand with LeapMotion, the user can touch a volume button projected on a piece of paper. The beads in the front move up and down in response to the user's volume operation. The second is the control of the appearance/disappearance of information by using beads. We adopt blackout curtains with 99% visible light absorption and a projector. Blackout curtains absorb environmental light well, and the user cannot recognize the existence of the curtain. So the system can control the appearance and disappearance of the beads by moving them to the other side of the curtain or not.
