Japanese scientists are now just one step closer to make the stuff of sci-fi films into reality after creating a hologram that can also be felt. By using the ultrasonic waves, the scientists have developed software that creates pressure when a user’s hand “touches” a hologram that is projected.

In order to track a user’s hand, the researchers use controls sticks from Nintendo’s Wii gaming system that are mounted above the hologram display area. The most significant advantage of touchable 3d images is that this technology could be used to replace other physical objects, making it economical and environmentally friendly.
