Today, many teenagers have already put technology to good use. Here are two good examples.

• A new reader (阅读器) for the blind

The two 14-year-old students, Meng Shuqi and Feng Boyao, are from Taiyuan. They invented a new kind of reader to help the blind read books. The new reader can turn words into raised dots (盲点) when connected to a computer.

As we know, the blind read by touching raised dots. However, there weren’t many books for the blind in the past, and it was difficult for them to get new information in time. As the old readers in the market were very expensive and difficult to use, the two students decided to invent the new reader which was easier to use. They hoped that the new reader could be widely used to help more blind people.

• A smart system for the old

A 16-year-old American boy Vetri Vel created a smart system. It is made up of a small computer and a camera. The system can catch the heat signals (热感信号) of a fallen person and send messages for help at once.

After Vetri’s neighbor had fallen down alone at home, Vetri realized that falling down was a common problem for many old people. It may even lead to death. Vetri hopes that his invention can help more old people in time.

Teenagers’ technological inventions full of love and intelligence can make our lives easier and more convenient. Why not have a try?
