A South Korean industrial designer has come up with a satirical solution for "smartphone zombies" who can't take their eyes away from their screen long enough to stop themselves walking into a wall or other obstacle.
Paeng Min-wook, 28, has developed a robotic eyeball he has dubbed The Third Eye, which obsessive mobile phone users can strap to their foreheads so they can browse injury-free on the go.
The device opens its translucent eyelid whenever it senses the user's head has been lowered to look at a smartphone. When the user comes within one to 2 meters of an obstacle, the device beeps to warn of the impending danger.
