D 盲人智能眼镜 说明文 ☆☆☆☆ 6分钟
The future may be easier for the blind. To help them live a normal life, a company is developing the smart glasses—AngelEye.
Cai Dongyue was born blind. “I can walk with guide sticks(拐杖), but I can only know the things near me,” Cai said. So when he learned about the smart glasses, he went to try them. “At first, I worried that I might hit(碰撞) something on the street,” Cai said. “But later I found the glasses were very useful. They have helped me walk farther on my own.”
AngelEye have small cameras(相机). They can take pictures and send them to a minicomputer to be identified(辨认). After that, the glasses will tell users what to do.
