< p > the first smart shoe in the world is called "Le Chal", which means "come together" in Hindi.

This intelligent "guided shoes" was developed by Anirudh Sharma and Krispian Lawrence of MIT Media Laboratory.

These magic shoes can be linked to smart phones. As a tactile navigation system, wearable technology devices are really hot recently, but some of the cool devices are the ones that allow you to read mail on your wrist watch.

Wearable technology should be an important way to change the lives of some people.

Imagine that if the blind people have these wearable devices, life may become more convenient.

< p > the basic principle of these shoes is very simple. You only need to tell your cell phone where you want to go, app will use voice recognition software to pform information, then use the navigation system to plan the route.

Once you start off, as long as you turn to the corner, the shoes will vibrate at the foot. You need to turn left, the left foot vibrates, and the shoes on the right side will vibrate when you need to turn right.

When you reach your destination, your shoes will vibrate more strongly.

< p > although it can guide the blind, it is impossible to rely entirely on this pair of shoes.

Blind people also need to pay attention to obstacles on the road ahead, and take extra care when turning corners.

Having such a pair of "guided shoes" has been a great improvement.

In addition to guiding the blind, these shoes can also be used as pedometer to measure the amount of fat that your body burns during exercise.

For visually impaired people, these shoes cost 40 to 50 dollars, much cheaper than a pair of Nike.
