Nokia's Ring That Can Control Your Mobile Phone
Nokia Research Center creates subtle input device for phones that looks like a piece of jewelry.
Researchers at Nokia have created a magnetic ring that works as an input device from which you can control your mobile phone. The ring is called Nenya, the name of Galadriel's ring in The Lord of the Rings trilogy, and it is tracked by a wrist-worn ‘baselet', which connects to the users phone via Bluetooth.
Twisting the ring on your finger causes changes in the magnetic field, which are picked up by the base bracelet and transmitted to the connected mobile device. As you rotate the ring, this effectively scrolls through different functions such as turning up your music, putting a caller on hold or updating social network sites. Pushing the ring towards your fingertip works like a ‘select' button and the instruction is sent to your mobile.
