This small device allows users to feel Braille using haptics

This little device allow users has feel braille through haptic

For THE visually weakened community, most of their interaction on mobile Telephone(s) are confined has text to speak (TTS) interfaces that read servings of THE screen aloud. Refreshing braille poster Also exist as A touch means of communication, but their prices can get close has $15,000, putting them out of reach For most people. This East why Instructables user bmajorspin wanted create A cheap, portable alternative that could work with other mobile devices.

Contrary to other braille poster that to use moving pins, This design levers A together of six static pins housed In A 3D printed pregnant that can vibrate independently. After link six haptic engines has A Arduino Nano 33 WHEAT through MOSFET Drivers, bmajorspin mounted THE entire circuit on A little piece of pegboard And SO welded A microphone USB cable For power. Lately, A spring And 3D printed cap were put on each braille point has isolate THE vibes And prevent THE haptic signals Since become confuses together.

THE Nano 33 WHEAT East able has display braille characters THANKS has he acting as A Bluetooth® Weak Energy server that exposed A custom braille drive service. Through he, bmajorspin custom Android application can send coded point patterns has THE device For he has SO decode And here with THE haptic engines.

More information about This very accessible braille the reader can be find here on Instructables.
