    Ultrasonic force field provides tactile sensations in midair
    Holodeck, anyone? Researchers at Bristol University are developing a system known as UltraHaptics that uses ultrasonic force fields to project the tactile sensations of objects in midair. Currently used for a haptic computer interface, the system might eventually enable touchable holograms.
