Curve sketching is a hard task for blind and visually impaired pupils and students, but it is an essential part in education. To help those students as well as their colleges, teachers and other people to prepare good tactile function plots the platform independent console program
SVGPlott
was developed. It enables users without any special knowledge about creating graphics for blind or visually impaired people to prepare highly adaptable mathematical function plots in the SVG format, which can also be used for audio-tactile exploration.
SVGPlott
was developed in a user-centered design process, including teachers and users. We show that blind and sighted users can prepare function plots including key as well as an automatically generated textual description not only for tactile, audio-tactile and print output, but also for usage on a dynamic tactile pin device and as a high contrast visualization for low vision people.
