India's Sumit Dagar introduces Braille SMART - the world's first smartphone for the blind!
The world's first smartphone for blind people has been introduced in India. Sumit Dagar, with a postgraduate degree from National Institute of Design, is collaborating with the Indian Institute of Technology to create the Braille SMART.
This smartphone device uses Shape Memory Alloy technology, which is based on the concept that metals can expand and contract while remembering their original shape after each use. According to Dagar, the Braille SMART touch screen is capable of "elevating and depressing contents to transform into touchable patterns."
The screen is composed of a grid of pins that move up and down as required in order to represent Braille characters. Dagar began working on this project 3 years ago and says that while the phone is still a working prototype, blind people will soon be able to read SMS messages and emails through the conversion to Braille patterns.
