Having physical particles levitate to form a display almost seems like a small step towards hologram. But in terms of usability, this technology represents a huge leap towards possibly including physical and haptic feedback while interacting with three-dimensional images with hand gestures. Imagine being able to clasp your hand(s) to grab the particles to move an object, having physics that allow you to push or pull particles with the palm of your hand or morphing an object by sculpting it with your hands. The race between tactile display and levitating particle display is definitely on.
