Amazing Invention By An Indian Student

Sumit Dagar is a post-graduate student from IIT Delhi has invented a unique smart phone that blinds can use with more functions than to just answering phone calls. As technology plays very important role now a days and Indian students have given lot of inventions already in different fields of technology. But this invention would be unique of its kind, now Blind people can use smart phone with all its functions.

As every one use smart phone except blinds but now blinds can also use smart phone with this new invention, an Indian has released a new Braille version of the phone.

The basic concept behind the phone is the use of the simple ‘Shape Memory Alloy’ technology. According to the technology, metals remember their original form and expand/contract to the original form post use. The phone comes with a host of pins under the screen which elevate or depress to form letters and words in Braille. The pins can be felt on the screen.
When a user sends a message, the phone deciphers it and converts it into Braille. The pins then move accordingly to form the message in Braille. All other elements of the phone are like any regular phone. Whether the text of even apps has been translated and how well the phone works without connectivity is still unclear.


Developed by Sumit Dagar, who is still working on setting up his formal organization at the Center for Innovation Incubation and Entrepreneurship, located in IIM-A, the phone is the world’s first Braille smartphone.

But how does the phone work? The messages and texts are sent as regular messages. However, instead of a smooth glass panel, the phone comes with depressions. The innovative ‘touch-screen’ elevates and depresses contents into touchable patterns which can then be deciphered by the blind.
The initial prototype is under testing at L V Prasad Eye Institute in Hyderabad.  According to Sumit Dagar: The response during the test has been immense. It comes out as a companion more than a phone to the user. We plan to do more advanced versions of the phone in the future.”

It is definitely a great achievement and we wish the young innovator the very best!
