Touchscreens have transformed the humble
phone into a powerful computing device, one
enabling us to take and share pictures, email
on the go – even watch films.
But the touchscreen revolution has left out one
sector of society – the visually impaired. The
lack of textured buttons means blind people
are unable to use them.
Designer Sumit Dagar has invented a prototype
Braille smartphone which may give the world's
300 million visually impaired people the first
phone developed with their needs in mind.
