Here is one of those things that make us understand how many degrees of separation can exist between science fiction and reality. Some fields of knowledge are still in a phase of pure speculation, others in an advanced research phase, still others are about to take flight in the form of technologies offered to the mass.
This is the case of holographic displays, which have long been in the notebooks of science fiction writers and successful directors (who doesn't remember Star Wars?).
RealView 3D achieves the full potential of such a technology, with a device capable of producing the points of light that make up the image, one by one, as pixels that float directly in mid-air: the effectiveness of the result leaves to mouth open. It seems to witness one of the refined special effects of Hollywood.
The first applications in the medical field really give hope: the possibility of interacting and operating on three-dimensional models through an interface of this type will allow medical training to take a crazy leap, and to make learning faster and more effective.
And that's just the beginning.
