Until now smartphones have been impossible to use for disadvantaged people, such asblind people.

Although applications like Siri have solutions, exhibitor of TED Summit in Dagar had an idea for a more efficient solution: a smartphone specifically designed for people who have visual problems.

 The phone, which has no official name, has a screen made up of a grid of pins which move up and down to form shapes and characters in braille when a text message or an email is received. The appliance uses the so-called Shape Memory Alloy technology in which each pin that expands retracts to its original flat.

In an interview with the Times of India newspaper the phone was described as “the first Smartphone for everybody in the world… It will be a ver good helper, definitely more than a phone, a companion”.

The National Institute of design in India, got the idea three years ago and are now working with IIT Delhi in the prototype, which is being tested in the LV Prasad Eye Institute. The team hopes to launch the phone in the end of 2013, at a price close to $185.
