The world is a dangerous place. You can walk around, playing on your cell phone quite innocently, and suddenly find yourself in road traffic, falling into a fountain, or meeting a wild bear. Our ancient ancestors long struggled with the task of walking while texting, hoping for a solution.
Now, thanks to modern technology, we have one. Industrial designer Minwook Paeng invented the Third Eye. This is a gyroscopically controlled ultrasonic sensor that activates when you tilt your head down. It buzzes you when you are about to encounter an obstacle.
