CES 2014: Smart lamp changes colour to aid sleep

There is no shortage of apps and devices that track sleep, says Withings' Alain Amador, but not a lot of technology that actively helps us doze off.

The Withings Aura is a special lamp that emits certain colours to aid the various stages of falling to sleep and waking up.

In a makeshift dark bedroom on the show floor at the Consumer Electronics Show in Las Vegas, Mr Amador demonstrated the lamp to the BBC's Dave Lee.
