Two vibrating rings which can guide the wearer around a city via global positioning satellite (GPS) have been unveiled by a British designer at the Royal College of Art. The rings are the invention of Gail Knight, who developed them as a way of helping women feel safe in areas they are unfamiliar with.
Buzz for direction

Not all of the necessary electronics could be put into the rings, so the device controller is worn either around the neck or clipped on to clothing.
The controller has a display of eight digits, which allows for a postcode to be entered. It also houses an electronic compass and GPS system, which is what powers the device's navigation. The signal is then transmitted to the two rings, inside of which are a small vibrating motor and antenna.
The rings buzz for left and right, and have different vibrations for forwards and backwards. Both buzz when going in the wrong direction.
