Using Ultrasound to Feel Virtual Objects

• Technologyreview.com
 

A startup called Ultrahaptics aims to make gesture control and virtual reality more engaging by using ultrasound waves to let you feel like you’re touching virtual objects and surfaces with your bare hands.

Tom Carter, cofounder of Ultrahaptics and a computer science graduate student at the University of Bristol, says the startup’s technology could improve upon touch-free interfaces, such as those enabled by Microsoft’s Kinect, or Leap Motion’s device, by reflecting air pressure waves off the hand in a way that can create different sensations for each fingertip. “You actually feel like you’re interacting with a thing and getting immediate tactile feedback,” he says.
