Using a high-tech 3-D printer, a Rutgers undergraduate and his professor created sophisticated braille maps to help blind and visually impaired people navigate a local training center.<\/p>\n
The three plastic tactile maps are for each floor at the Joseph Kohn Training Center, a state-funded facility for the blind and visually impaired in New Brunswick. And the goal is to print maps for all of the center\u00e2\u20ac\u2122s students.<\/p>\n
\u00e2\u20ac\u0153It was a very fulfilling experience,\u00e2\u20ac\u009d said Jason Kim, 25, a senior mechanical engineering student in the Department of Mechanical and Aerospace Engineering in Rutgers\u00e2\u20ac\u2122 School of Engineering. \u00e2\u20ac\u0153I learned a lot. The most difficult part was trying to imagine what it would be like to be blind myself so I could better tackle the problem, and it opened my eyes to the whole visually impaired and blind community.\u00e2\u20ac\u009d<\/p>\n
Howon Lee, an assistant professor in the Department of Mechanical and Aerospace Engineering whose research focuses on 3-D printing, said the maps are a form of GPS for the blind and visually impaired.<\/p>\n
\u00e2\u20ac\u0153Design, using this technology, practicing \u00e2\u20ac\u201d everything is important \u00e2\u20ac\u201d but I think what is more important is to put yourself in their shoes,\u00e2\u20ac\u009d Lee said.<\/p>\n
Joseph Kohn Training Center staffers lauded the durable maps, saying they would be very helpful for center students. The center has clunky, old wooden maps with a few braille labels on walls.<\/p>\n
Professor Lee said he got the idea of making 3-D maps after visiting the Korea Institute of Science and Technology in South Korea. The institute created educational materials for small children with a 3-D printer, and he was impressed.<\/p>\n
A 3-D printer \u00e2\u20ac\u201d very similar to an inkjet printer \u00e2\u20ac\u201d uses computer-aided design software. The technology was developed in the 1980s, but advancements have accelerated in the last five years, Lee said.<\/p>\n
\u00e2\u20ac\u0153Instead of printing letters on top of a 2-diminensional sheet, you just do this over and over again, layer upon layer, until you have a final 3-dimensional product,\u00e2\u20ac\u009d Lee said.<\/p>\n
The Joseph Kohn Training Center gives blind and visually impaired people a chance to learn largely vocational skills so they can become independent. The intensive, 20-week training program is free for New Jersey residents. Students, who are at least 18 years old, gain the skills needed to attend college, find jobs or become independent homemakers. Training takes place on weekdays, and the center has overnight residential space for 24 people.<\/p>\n
When someone suffers a loss of vision, learning how to better use the senses \u00e2\u20ac\u201d hearing, touch, taste and smell \u00e2\u20ac\u201d for day to day living is the largest adjustment, according to the center.<\/p>\n
Kim said he approached Professor Lee last spring, looking for a summer project that would help the community.<\/p>\n
\u00e2\u20ac\u0153I had just learned how to use SolidWorks {3-D modeling computer-aided design software} and so this summer project would be a great way to exercise a skill I had just acquired, just for the community,\u00e2\u20ac\u009d Kim said. \u00e2\u20ac\u0153He told me about this opportunity and I thought it was perfect.\u00e2\u20ac\u009d<\/p>\n
Lee launched the project and Kim jumped in. Both men knew nothing about braille, so they had a steep learning curve.<\/p>\n
They visited the center several times to get feedback from faculty and students. They finished designing the map near the end of last summer.<\/p>\n
\u00e2\u20ac\u0153One of the things we saw with conventional braille printed on paper is that it doesn\u00e2\u20ac\u2122t last long,\u00e2\u20ac\u009d Lee said.<\/p>\n
The new maps \u00e2\u20ac\u201d made with state-of-the-art 3-D printers at Rutgers \u00e2\u20ac\u201d are a little larger than a small computer tablet. They\u00e2\u20ac\u2122re in a binder so students can easily carry them for reference. They also have a legend, or guide, in braille, a feature missing from prior maps. The legend helps limit the amount of map training needed.<\/p>\n
Lee said there\u00e2\u20ac\u2122s only one copy of the maps so far and the goal is to lower map-making costs so every student at the training center gets a map on day one.<\/p>\n
As for the future, Lee said he\u00e2\u20ac\u2122s interested in developing 3-D maps of the Rutgers\u00e2\u20ac\u2122 campuses and the city of New Brunswick.<\/p>\n
The idea is to \u00e2\u20ac\u0153give freedom, extended freedom, to navigate and go from one place to another without worrying too much,\u00e2\u20ac\u009d he said.<\/p>\n
