You can chose between having graphics actually produced in tactile form or described. If you opt for the latter, the descriptions will be written by an expert. The information in some graphs and charts is best rendered in tactile form by converting them into a table. Photographs are never reproduced. To obtain the highest quality in our tactile graphics, we use a combination of computer technology and human skill.
Most graphics contain some words, letters or numbers.
These are produced in Braille on the computer using the MegaDots software . The same software is used to position these components on the page so that the graphical parts can be drawn around them. Then a skilled human operator draws the lines and curves on the graphic using various toothed wheels. This must be done on the reverse side so that the figure will be right-side up. Shaded areas are filled with various tactile textures.
