Optical Braille Recognition

A technology that uses cameras or optical sensors to detect and interpret embossed Braille characters, converting them into digital text. Optical Braille recognition works by capturing images of Braille pages and analysing the patterns of raised dots — typically by detecting shadows cast by the dots under controlled illumination. OBR enables sighted people who do not read Braille to access Braille-written content, and supports archiving and digitisation of Braille documents. It is the Braille equivalent of optical character recognition (OCR) for printed text.
