UltraHaptics technology creates 3D shapes in mid-air using focused ultrasonic waves.
Potential application include computers, home appliances, and cars.
Virtual reality gaming would greatly benefit from the addition of tactile feedback.
Unlike other systems which just recognize hand gesture, haptics provide actual feedback on the user's skin.
Microsoft's Kinect for Xbox has long offered motion sensing input for gaming and multimedia controls, but it lacks the haptics factor.
Oculus VR, bought by Facebook in 2014 for $2 billion, is at the forefront of virtual reality technology.
