While apps like Siri and SayText do offer a good deal of assistance, Sumit Dagar had an idea for a more effective solution: a smartphone that's specifically designed for people who have trouble seeing.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 "world's first Braille smartphone ... a companion more than a phone."
