Devices with feeling: new tech creates buttons and shapes in mid-air

(UltraHaptics technology creats 3D shapes in mid air using forced  ultrasonic Waves)

UltraHaptics is a young company with a big dream: changing the way we interact with electronic devices.

Their technology creates tactile three-dimensional shapes literally out of thin air, using ultrasound. The company's tagline says it all: "Feeling without touching."

Through an emission of sound waves, sensations are projected through the air and to the user.

Changes in air pressure are perceived as suspended tactile surfaces, creating invisible -- but tangible -- interfaces.
