Two n Inth graders from Austin, the US, have created a" smart cane( 拐杖 )". It helps people who 1 visually impaired(视力受损的).
Ahyan Hassan and Hasan Rizvi made the cane for a school 2 competition. The cane helps a person to see obstacles(障碍物) up to 1.5 meters away. This design 3 first prize in the competition." We put blood, sweat and tears 4 this invention. We were really excited to win, "Hassan told local newspaper KXAN News.
The boys have been best friends since the seventh 5 ."We have lots of similarities. We like going outside to swim, play soccer and so on. We 6 like science when it comes to things, "Hassan explained." When we see something, we always want to know 7 it works or why it works."
Their idea came from the old canes of Rizvi's grandfather." My grandfather is almost8 and has bad legs, "Rizvi said." It's9 for him to get from place to place."
So the boys came up with an idea. They 10 some sensors( 传感器 ) to the cane. When they" see" things, they send information to the cane, which can then shake to 11 the user. In this way can users keep far away from a lot of accidents.
I12 this can encourage other people to think outside the box, and that's my goal, "Rizvi said. It would be 13 if one day the'smart cane 'became an actual product(产品), "Hassan added.
Both boys hope to become 14 when they grow up. They also plan to improve their product to compete in more science fairs in the 15 . It seems they are expecting the future life.
