Utilizing scalable vector graphics in the instruction of mathematics to the print impaired student

Abstract

The XML based Scalable Vector Graphics imaging language provides another tool for enhancing the accessibility of mathematics for both the visually impaired and the dyslexic student. SVG possesses two attributes applicable to our purpose. As its name implies an SVG image is scalable, it can be enlarged to fill the viewing area of a computer monitor, then zoomed for further magnification, and do so without sacrificing clarity, thus aiding the visually impaired. An SVG image can also be manipulated in real time. For example, one or more text characters may be highlighted in response to a keyboard or program event. This attribute has potential for the dyslexic student. © Springer-Verlag 2004.
