Vibrating rings guide city tourists
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.
"I admit that, as it is rings, they're obviously more attractive to women - and I'd been looking at women and their position in the public sphere, and how safe they feel in a public environment," she told BBC World Service's Culture Shock programme.
"I wanted to avoid the route of attack alarms, which nobody really uses, and just find a way of making people feel confident.
"I integrated that with walking and London, both of which I like, and came up with this device that was very feminine - but at the same time a piece of consumer electronics."
