Holograms that Respond to Touch
Japanese scientists have developed a technology that allows holograms to respond to human touch.
Using ultrasonic waves and Nintendo Wii controllers, scientists created a software program that tracks the movements of a person's hand and allows holograms to respond to the "touch" of a hand.
Possible uses include holographic controls on hospital machines that could replace easily contaminated physical controls.
