Samsung has developed a way for smartphone owners to type on a table or other surface as an alternative to tapping on the handset's own screen.
Its SelfieType software tracks the user's fingers via the phone's front-facing camera and works out where the taps would correspond to being on a Qwerty keyboard.
Chris Fox tried it out at the CES tech expo in Las Vegas to see if it works in practise.
