This one is called Vie - after the French word for ‘life’. It design at competitions of students with creative minds design the futuristic gadgets.

Vie which fits on your hand like a glove. It is designed for those who go out running/jogging/walking in the dark and apparently is aimed at keeping them safe from harm with its color E-ink screen that can display your location on Google Maps thanks to its GPS receiver. And if you are serious danger here is what it can do:

Send a stress beacon in case of emergency to all VIEmates in the vicinity, or even straight to the police depending on urgency. A sign of heart failure automatically sends a SOS to the nearest hospital.

The other features built-in such as the bluetooth hand shakes to transfer information, one handed operation with tactile feedbacks as the interface, and even an online community. Vie, somehow, is also a health monitor and a personal trainer. All this with a simple watch battery. Want to try?
