The phone, which has yet to be officially named, has a screen comprised of a grid of pins, which move up and down to form into Braille shapes and characters whenever an SMS message or email is received. 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, an interaction design graduate of the National Institute of Design (NID), came up with the idea for the phone three years ago. He's collaborating with IIT Delhi on the prototype, which is being tested at the LV Prasad Eye Institute. The team hopes to release the phone by the end of 2013, for a about $185.
