This assisted reading device could one day eliminate the need for braille By Shawn Knight on April 17, 2014, 2:15 PM
A handful of researchers at MIT’s Media Labs are working on a device capable of helping visually impaired and blind individuals read without the need for Braille. The FingerReader is equipped with a small camera that scans printed text and reads it out loud using a synthesized voice.
The current prototype is worn on the finger and is said to weigh no more than a regular ring. It uses heavily modified open source software and can read 12-point and larger printed text as well as on-screen text from, say, a Kindle.
