An alarm clock that will not switch off until it has seen that you are fully awake has been invented by a student at Strathclyde University.
The puzzle clock, created by Liam Hastie for his engineering degree, is designed to overcome ‘sleep inertia’ — the groggy feeling which, scientists say, can impair mental faculties for 10 minutes, but sometimes for up to two hours after waking.

The wall-mounted alarm clock can be switched off only when its user climbs out of bed, stands directly in front and repeats, by pressing coloured buttons, a sequence generated randomly each morning.
