Successfully developed a touch screen display for brave blinds

With this special display type, the visually impaired can use a smartphone, tablet or any touch screen device.

One of the weaknesses of multimedia content on the screen is the inability to reach the visually impaired.

Visually impaired people cannot read the content on the screen and cannot see the interactive buttons. However, a special touch screen that can float content on the screen in Braille will solve this problem.

The screen was created by a team at the University of Michigan, USA. It has the ability to create a tactile surface , floating letters on the screen so that the blind can sense and thus understand the content on the screen.

Braille will encode characters, words and symbols into dots for blind people to read by touching them.

The blind braille system was developed in the 19th century in France by Louis Braille, based on a military language system that allows soldiers to read messages in the dark. Braille will encode characters, words and symbols into dots for blind people to read by touching them.

There is a Braille display device that can turn text on a computer screen into Braille but it is very expensive and can only display one word at a time. This is not an ideal device for visually impaired people when they want to read books or newspapers. It also cannot display information such as graphs, tables or charts.

Touch screen exclusively for the visually impaired.

So Professor Sile O'Modhrain, together with Professor Brent Gillespie and Dr. Alexander Russomanno at the University of Michigan, developed a compressed air system that can fully display the Braille types on the touch screen. Instead of using pin pins, the system uses a liquid or gas system that can fill or shrink tiny bubbles on the screen to create Braille.

Researchers want to bring the device to market in the next few years to help more visually impaired people.
