Nippon Scientists are one step closer to realize scenes that were hitherto characteristic of science fiction films after creating a hologram that can also be felt. Imagine, then, not much later, a book or a light switch that appear only when you really need them.
Until now, holography was only for the eyes, and if you tried to touch her, his hand went through it, but now we have a technology that also adds the sensation of touching the holograms.
The three-dimensional images, holograms, usually appear on credit cards, DVDs and CDs to prevent counterfeiting. The larger ones have also been used in the entertainment industry. But by using ultrasonic waves, scientists have developed software that creates pressure when the hand of a user "touches" a hologram projected. (To track a user's hand, researchers use the controls of the popular Nintendo Wii console, which cover the projection area of the hologram.)
So far the technology has been tested with relatively simple objects, although researchers have more practical plans, and virtual switches in hospitals, for example, and other places where contamination by contact is a problem. Also, this technology could be used to replace other physical objects, making it economically and ecologically.
