Engineers have created a glove for learning Braille.

The BrailleWear glove has a built-in electronic module with a small camera and a light. Light hits the printed braille dots at an oblique angle, causing each of them to cast a shadow. The software analyzes the received image and reads the text to the user using a synthetic voice system. The idea is that a person will eventually learn to recognize symbols by touch on their own. BrailleWear gloves should go on sale before the end of the year and will cost about $300.
