In the past ten years, great progress has been made in technology. It seems like everything has been greatly improved. But there is one thing unlike them. It was invented over 100 years ago but remained unchanged until now. I'm talking about a blind walking stick.

The white stick has been used by many blind people for a long time. However, it hasn't really been improved, until a blind engineer named Kursat decided to do something to change that. He hoped his invention would help the blind.

He invented a smart stick called the WeWalk. The smart stick uses built-in speakers and different sensors (传感) to warn about possible dangers. It helps blind people in navigating (航行) around their environment. It makes their travel much easier. The stick is priced at around $

500. It is less than half the price of most smart phones. Most people can afford it. This invention is going to change life a lot for the blind. 

Kursat well understands the difficulties that the blind face. That's because he is blind himself. He decided to put his knowledge of technology into inventing something. It would not only change his life, but also the life of many others.

"In these days, we are talking about flying cars. But the blind have been using just a simple stick. As a bind person, when I am at the bus stop, I don't know which bus is coming or which stores are around me. Now, that kind of information can be provided by the WeWalk," he said, "I believe life of the blind will be much easier and safer. "
