Many blind or partially sighted people rely on braille, a unique system of raised dots that can be read by touch to read.
The few devices currently on the market that are able to convert digital content into braille are cumbersome, and so expensive they are beyond the budget of most people. The size of a computer mouse, the latest gadget lets blind people read text on a laptop, iPad or iPhone either by moving the device from left to right or choosing an ‘auto-scroll’ option which takes them to the next line. They can also skip lines, paragraphs or pages by single, double or triple taps of a button.
