Graphics in STEM and other professional publications often use color as an important part of the content. Color is one of many challenges to making graphics accessible today. Word descriptions are used to "make simple graphics accessible", but tactile versions are necessary for adequate access to more complex graphics such as maps, GIS diagrams, and bar and pie charts. Color in tactile graphics is normally represented by some kind of pattern, texture, or other tactile quality. Experts in the field typically use standard graphics software to create the image for a tactile graphic. They remove colored regions and replace them by patterns. then the file is printed on swell/capsule paper. This process is labor-intensive, and swell paper is expensive.

Users of ViewPlus embossers and version 8 or later of the Tiger Software Suite have a considerably simpler and less expensive option. A print driver option permits substitution of patterns, so editing of color is not needed. The color to pattern choices maybe selected from a variety of internal files, or users may create their own patterns. Custom patterns may be created or edited by sighted users in an editor that is included in the Tiger Software Suite. Any user, whether sighted or blind, can create/edit patterns using any text editor.

Finally, the resulting tactile graphic is printed by the embosser using inexpensive braille paper. Most blind readers find copy embossed on a ViewPlus embosser far superior to swell paper images.

A new type of daisy books, "Fixed-layout DAISY" is proposed, in which the whole page is treated as a multi-layer picture, the second layer of which has the same form as the original print document. A DAISY (EPUB3) player can read out any texts on the transparent front layer together with highlighting them. By making use of Fixed-layout DAISY, "ChattyBox" is developed, which provides dyslexic people with various innovative online accessibility services such as automatically converting e-born PDF into Fixed-layout DAISY, playing DAISY books back with a popular browser, etc.

MathML has been successful in improving the accessibility of mathematical notation on the web. All major screen readers support MathML to generate speech, allow navigation of the math, and generate braille. A troublesome area remains: handling ambiguous notations such as . While it is possible to speak this syntactically, anecdotal evidence indicates most people prefer semantic speech such as “absolute value of x” or “determinant of x” instead of “vertical bar x vertical bar” when first hearing an expression. Several attempts to infer the semantics have had some success, but ultimately the author is the one that definitively knows how an expression is meant to be spoken. The W3C Math Working Group is in the process of allowing authors to convey their intent in MathML markup and this paper describes that work.
