Do you know Snail? It’s a wheel around a blind person’s thumb to read out loud a Braille text. Equiped with a touch sensitive surface, the wheel detects the Braille patterns surface.
Text can be read and recorded for later rendition and the device can be paired with a Bluetooth headset for better discretion.
Typically this could be a great tool to speed up reading for the blinds and decreasing the need to learn Braille.
