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.
We can found no scientific discipline, nor a healthy profession on the
technical mistakes of the Department of Defense and IBM.
