From the outside, it sounds as if someone is using a jackhammer inside the Golden Valley office of Volunteer Braille Services.
But that noise is actually huge printers -- called embossers -- tirelessly churning out pages and pages of Braille dot coding that the company makes for schools, businesses and individuals.
Volunteer Braille Services (VBS) is the only entity in Minnesota, other than the state government, that takes books and other reading materials and transcribes them into Braille. Although the work has remained steady for the 43-year-old company, the fact that fewer blind people are learning Braille nowadays is a constant source of frustration.
"It's always been kind of disappointing.... It's a literacy thing," said VBS President Dorothy Worthington. "I know you can get a lot of things on audio and you can have your computer screen read to you, but I'm not an advocate for either."
New technologies, such as a computer program that reads the screen, as well as a shortage of Braille-certified teachers, have contributed to the decline.
Blind people who know Braille are far more likely to have careers. There is a 70 percent unemployment rate among blind people in the United States, but 90 percent of those who have jobs know Braille, said Jennifer Dunnam, president of the National Federation of the Blind of Minnesota.
"This is an issue that we have been having a great focus on for the last number of years," Dunnam said. "We're working hard to get [Braille] revitalized."
