Braille Label maker developed by students

Students design portable Braille label maker

One everyday problem for people who are blind or have very limited sight is distinguishing things that are completely identical to the sense of touch, such as different CDs and DVDs, or canned goods that are all the same size and shape. To cope with that difficulty, many people make Braille labels to attach to these items.

But the existing devices for doing this are either expensive and heavy — one costs about $650 and has limited portability — or light and inexpensive but very difficult for a blind person to operate, and limited in the number of characters they can imprint.

A team of MIT students in last fall's Product Engineering Processes (2.009) class searched for a better way. They came up with a prototype device that is small and easily portable, can produce the entire panoply of possible Braille characters (including commonly used two-character contractions), and can be relatively easily loaded and operated by touch. Although it is still under development, they hope the device, which they have named the 6dot Braille Labeler, can ultimately be produced for sale at around $200.

Some of the students continued to refine the product after the class ended, producing an improved version that won a $7,500 prize in the spring IDEAS competition (a joint project of the MIT Public Service Centre and the Edgerton Centre that recognizes innovations that benefit communities worldwide). Eight students from the mechanical engineering department, some who graduated in June and others who are still enrolled, joined by two others, are in the process of forming a company to continue development of the labeller. Over the summer they conducted field tests around the country with 25 potential users of the product, giving each about a half-hour to work with the device.

"Blind people really wanted to see this product on the market," says Karina Pikhart '09, who is CEO of the new company. "We worked really closely with blind people" in developing it, she says, because "you really can't develop a product without being in close touch with the people you're developing it for. They gave us a lot of good feedback." One of the comments they received was that the clear quality of the Braille produced by the device "felt like what really neat handwriting must look like," she says.
