Okay, so next up is a vibrating ring that you wear in bed. But before you think we're retreading some intimate old ground let me point out that it's actually designed to gently wake you in the morning. Meng Fandi's Ring concept is a discrete alarm clock that allows two people to be roused at different times without disturbing the lucky bugger still sleeping.
Consisting of two rings and a recharger-base, you set the required time and then slip the ring onto the tip of your finger; in the morning, it gently vibrates until you pop it back on to charge. While any eventual production version would be great for people tired of blaring sirens in the morning, it also could be a boon to the hearing-impaired.
