Tablets turned into Braille keyboard by US researchers

A team of US researchers has devised a way for people with impaired vision to use the touchscreen of a tablet such as an iPad as a Braille keyboard.

·  It turns some previously fundamental thinking about how to make technology accessible to blind people on its head.

· Instead of using a keyboard or mechanical writer, users type directly onto the flat glass.

·  The inventors used a novel design for the keyboard to overcome the lack of tactile features.

·  "Instead of having fingers that find the buttons, we built buttons that find the fingers," said Stanford's Sohan Dharmaraja, one of the researchers on the project.
