touchable holograms were originally a japanese invention that became further developed by american microprocessor company intel. touchable hologram technology is the closest modern representation of the holographic displays that one might see in sci-fi movies such as star wars and particularly in the star trek television franchise. this display is unique in that it can detect a user's touch by sensing movements in the air. the device then provides haptic feedback to the user by sending an ultrasonic air blast in return. in intel's demonstration of this technology, the display was showcased representing a touchless, responsive piano. a possible implementation for this technology would be interactive displays in public kiosks; because this type of display does not require a user to physically touch a screen, it ensures that bacteria and viruses do not get transmitted from person to person.
