Sumit Dagar, a 2011 TED fellow, is developing the world's first Braille smartphone.
He's collaborating with IIT Delhi on the prototype, which is being tested at the LV Prasad Eye Institute.
There are currently apps like Siri and SayText that can help people with visual problems tell what's on screens on use their phones.
The Braille smartphone would be different, allowing people to feel what's on the screen.
The screen is actually comprised of pins.
Those pins can move up and down to spell out emails and SMS messages using Braille characters.
It uses what's called Shape Memory Alloy technology, so as each pin expands, it remembers and contracts back to its original flat shape.
In an interview with the Times of India, Dagar describes the phone as "[the] world's first Braille smartphone ... a companion more than a phone."
Dagar came up with the idea for the phone three years ago.
The team working on the phone hopes it will be ready for sale by the end of 2013.
It's expected to cost about $185.
