Two months ago, researchers at the Georgia Institute of Technology have developed a special glove that can quickly and easily teach people relief-point tactile braille, which is used by blind people. This glove has a built-vibro motors on each of the phalanges, which are using the vibration transmitting information in accordance with the text written in Braille. Editor in chief of IEEE Spectrum Resource David Schneider was so interested in this idea that brought home its own analog of these gloves as a simulator for my 11 year old son.
To create a glove, David used a pair of transistors, vibro motors, purchased for $ 14 on eBay, and cables connecting them to the board Arduino Nano. He also developed a special program that ensures the correct operation of the glove.
David Schneider program displays on the screen in random order 1 of the 100 most frequently used words in the English language, sending vibrations to the correct finger with the appearance of each letter. In addition, he implemented learning through games.
