The world's first blind smartphone with braille created


 In India, the world's first smartphone for people with impaired or visually impaired has appeared on sale. The device is distinguished by its “screen”, which is a grid of contacts that forms the braille.
The smartphone implements Shape Memory Alloy technology, which is based on the shape memory effect (the phenomenon of a return to its original shape when heated, which is observed in some materials after preliminary deformation).
The screen of the smartphone, if it can be called a screen, includes a grid of contacts located from top to bottom in accordance with the requirements. This grid is a Braille alphabet, and various contacts are responsible for certain letters or characters.
The screen is a kind of translator and can translate plain text containing the letters familiar to everyone into Braille and vice versa.
