Researchers in the UK developed a computational technique that allows high-speed multipoint levitation even with arbitrary sound-scattering surfaces and demonstrated a volumetric display that works in the presence of any physical object. Their technique has a two-step scattering model and a simplified levitation solver, which together could achieve more than 10,000 updates per second to create volumetric images above and below static sound-scattering objects. They explained the technique achieved its speed with minimum loss in the trap quality and illustrate how it brought digital and physical content together by demonstrating mixed-reality interactive applications…read more.
