His Own Son’s Struggle Inspired ISRO Scientist to Develop a Drawing Device for the Blind

QUICK BYTES: Curated positive news from across the web. Read more.

Ever thought a blind person could draw as easily as a ‘normal’ person? Seems impossible, doesn’t it. But scientist Dilip Bhatt’s invention “Pragya” (named after his wife), changes all that. The senior ISRO scientist, who has long stints in Sriharikota and Allahabad to his name, is the father of a visually impaired boy, Nikunj. His own family was apprehensive about his son’s future and the limited opportunities available to him.

In order to let his son experience the joys of creating art and try his hand at drawing, Dilip decided to design a solution, and Pragya was the result.

“Blind people’s world is limited to six dots of braille and I wanted to change that. With my mechanical engineering background, I started looking at ways I could teach him geography and language,” he told IndiaTimes

He first took a 1.5′ x 1.5′ wooden board, and attached velcro to it. He then designed a pen that would release woollen thread. The thread, when released, sticks to the velcro, thereby providing a tactile canvas.

After the work is completed, the thread can be rolled back onto a spool situated on top of the pen. This simple, yet extremely useful machine secured a patent in 2000.

Pragya has been very well received for its innovative design, and the fact that it doesn’t require electricity. It is now prepared by blind people around around India, and is also used in several schools, even those located in remote areas.

Pragya isn’t Bhatt’s only invention. He has designed several other simple devices, ranging from toothpaste nozzles to easy-to-hold cutlery, all to make a blind person’s life easier.

Not surprisingly, for 22-year-old Nikunj, his father, who is also his best friend, is his role model.

“He learnt Sanskrit to help me revise lessons for my BA course. He has never made me feel that there are things I cannot do. I trek, I ride a bicycle and also perform on stage without fear,”  says Nikunj.
