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.

This sounds great for blind people. It even works for deaf people too, and can be designed very similar to existing 2d UIs, so there is little difficulty porting UIs to support it. The whole 3D support it just an extra bonus.
Finally people will stop complaining. (Score:5, Insightful)
On-screen keyboards will finally get tactile feedback.
