读写练习1 Yash Mehta, 14, got the idea for his first science fair project on a trip to Old Delhi, India. There, he visited a school for blind students and noticed that none of them used electronic braille (盲文) readers. They were just too costly. So he decided to build a more affordable one. His device uses tiny spinning motors to create vibrations that feel like the raised dots of braille letters. He then tested it with students at New Delhi’s Blind Relief Association, achieving 86% accuracy in braille reading compared to print. “I’ve always been a hardware guy. I’ve never been capable of software,” Yash says. But building his device required coding skills, which he learned by watching YouTube videos and reading Reddit posts. “Picking it up was cool,” he adds. “I love 3-D modeling, so having everything fit in the first time was just pure excitement.” Despite his initial joy, the process wasn’t without challenges. At first, he attempted to base his design on a TENS machine—a device that uses electric pulses to relieve pain, hoping these pulses could create the feeling of braille dots. When this approach didn’t work, he realized that instead of starting over, he only needed to change the way of spreading information to the finger. This idea helped him power through the development of his motor-based device. Yash’s research earned him the first-place Technology Award in the 2024 Thermo Fisher Scientific Junior Innovators Challenge. “I’m planning to add OCR,” Yash says. Right now, his machine translates computer text into braille letters. But with OCR, it could translate printed or handwritten text into braille. For those new to science fairs, Yash advises, “Try to find something that you think can be done based on your current abilities. Also, ask people in your community what problems they need solving. I think that’s the most important part—getting first-hand feedback.” ( )1.Which of the following best describes Yash’s braille reader A.Water-resistant. B.Budget-friendly. C.Pocket-sized.
