Modular Acoustic Levitation for 3D Path Visualisations


LeviPath is a modular system to levitate objects across 3D paths. It consists of two opposed arrays of transducers that create a standing wave capable of suspending objects in mid-air. To control the standing wave, the system employs a novel algorithm based on combining basic patterns of movement. Our approach allows the control of multiple beads simultaneously along different 3D paths. Several LeviPaths can be joined together to increase the interaction space.  The users can pick up the LeviPaths to take a closer look.
