In Brief

HandSight is a translation system that works for printed materials and digital screens alike

With HandSight, the blind may now read printed matter without worrying about having to translate to Braille.

The system works through a tiny camera mounted on the user’s finger. As the user traces their fingers across the lines of a book, the camera captures the printed words. A computer then turns these words into speech which is fed into the wearer’s ears.

The current prototype can read between 63 and 81 words per minute (wpm), a hopeful preview compared to an expert Braille reader who can read between 90 to 115 wpm, New Scientist reports.
