South Korean industrial designer Paeng Min-wook has developed what he calls the “third eye.” This device is designed to help those who are used to using their smartphone on the go to avoid obstacles.
The “third eye” is fixed on the forehead and opens its translucent eyelid whenever it notices that the user lowers his head and looks at the smartphone. If the user approaches an obstacle at a distance of 1-2 meters, the device beeps to warn of an impending danger.
A gyro sensor is used to measure the angle of the user’s neck, and an ultrasonic sensor is used to detect obstacles and determine the distance to them. The sensors are connected to an open source microcontroller. The product is powered by a battery.
Pang clarifies that his development is more of a satirical warning for “smartphone zombies”, rather than a real solution to the problem.
