Researchers Create Mid-Air Haptic Feedback System For Touch Displays 62

Bismillah writes "University of Bristol researchers have come up with a way to make touch screens more touchy-feely so to speak, using ultrasound waves to produce haptic feedback. You don't need to touch the screen even, as the UltraHaptics waves can be felt mid-air. Very Minority Report, but cooler." The researchers built an ultrasonic transducer grid behind an acoustically transparent display. Using acoustic modeling of a volume above the screen, they can create multiple movable control points with varying properties. A Leap Motion controller was used to detect the hand movements.

    A Theremin is a box with an antenna. You wave your hands and make "space sounds" - the music you heard in all those 1950s science-fiction movies. Ever play one? They are effin' difficult, because you're just waving your hands in the air using your muscle memory as reference points for tones only. Anyone who is good at playing a Theremin is a musical instrument genius.

    Um .. did you even watch the video?? They are using phased ultrasonics to create tactile points in space - no muscle memory needed.

What the scientists have in their briefcases is terrifying. -- Nikita Khruschev
