Here’s a device that will be really handy to people who are blind. Thanks to the geniuses at the University of Toronto, MIT and Stanford, the 6Dot Braille Label Maker was created, and is promised to cost less than half of the conventional Braille label makers. With just 6 keys, one for each of the dots of a Braille character, users will be able to enter up to 16 characters into the printer’s memory, which can then be printed on to a roll of label tape. The device, which runs on two AA batteries, isn’t only good for helping blind people identify objects, it can also be used to teach blind children how to read Braille.
