One of the drawbacks of all modern screens of computers, tablets, smartphones and TVs is the inability to use them by people with low vision and completely blind. The Michigan State University team has taken a big step towards solving this problem. Now they are engaged in the creation of a touch tablet that combines modern computer technology with Braille technology.
In the 19th century, Louis Braille developed a text messaging system using raised points on a flat surface. In his opinion, this could help the soldiers on the front line to read messages in complete darkness without revealing their whereabouts. However, the Braille technique did not take root in the army, but thanks to it, the blind and visually impaired all over the world were able to read.
There are currently devices that convert screen text to Braille, but they are very expensive and can still reproduce just one line, like a special South Korean watch. But what if we are talking about an article or a whole book?
University of Michigan professor Sile O'Modhrain is working with colleagues Brent Gilspi and Alexander Russomano to create a pneumatic system that uses microfluidic technology to control microscopic amounts of liquid or gas to fill or pump bubbles from a tablet screen. The Michigan research team intends to complete their work within two years.
