I used to work in a braille lab during my masters. Braille lab would generate braille books and reading material depending on blind students' request. For regular text, we used to do a simple text conversion and print it using a special printer called braille embosser. We used a software called duxbury for the purpose. http://www.duxburysystems.com/dbt.asp http://www.duxburysystems.com/dbt.asp For math(non single line), braille uses something called, nemeth code. So we used code almost all the math functions/equations manually in nemeth code. For graphics, we used to emboss 2d picture on a special paper. The process involved, scan the picture -> convert it into a grayscale -> remove all the noise -> take a print out -> use a tactile embosser to put it on a swell touch paper (http://www.abledata.com/abledata.cfm?pageid=19327&top=15312&ksectionid=19327&productid=76093&trail=0&discontinued=0 http://www.abledata.com/abledata.cfm?pageid=19327&top=15...) Typically, a chart or graph or waveforms were key in understanding the material. During the process I interacted with few blind cs engineers who were graduated and were working for Microsoft. At that time(10yrs ago), Microsoft was the best blind friendly company. They used the visual studio for daily hacking.
