The invisible objects you can touch thanks to ultrasound

Researchers in Bristol have created a device that makes invisible objects in mid-air that you can touch and feel.

The Ultrahaptics system works by focusing ultrasound waves emitted from a collection of tiny speakers.

Similar speakers are used on their own in cars to detect if you're about to collide with an obstacle.

The tech is one of many new inventions on show at this year's Consumer Electronics Show (CES) in Las Vegas.

BBC Click's Stephen Beckett spoke to Tom Carter, one of the company's co-founders, about how the technology could change the way we interact with our electronics.
