Braille is a tactile system of communication, used the world over by those with vision impairment. Like any form of language or writing, it can be difficult to teach and learn. To help solve this, [memoriesforbecca] has developed Becdot as a teaching tool to help children learn Braille.
The device is built around four Braille cells, which were custom-designed for the project. The key was to create a device which could recreate tactile Braille characters at low cost, to enable the device to be cheap enough to be used a children’s toy. The Braille cells are combined with an NFC tag reader. Small objects are given NFC tags which are programmed into the Becdot. When the object is placed onto the reader, the Braille cells spell out the name of the object. Objects can be tagged and the system programmed with a smartphone, so new objects can be added by the end user.
It’s a great way to teach Braille, and an impressive build that keeps costs down low. Details are a little thin on the ground, and we’d love to see more detail on how the actuators on the Braille cells work. We’ve seen similar projects before, like this Hackaday prize entry.
