The Fluid Interfaces Group at MIT Media Lab have developed a wearable device that can help people read printed text. The FingerReader is a special ring that could be used by the visually impaired or anyone who needs help with language translation.
The device scans a line of text for the wearer as they move their finger across a page. They then receive audio feedback of the words and haptic feedback of the layout (start and end of line, new line, and other cues).
The FingerReader can also detect and provide feedback when the wearer deviates from the baseline of the text, helping them maintain a straight scanning motion within the line. You can check out the wearable text-reading device in the video below:
