Abstract

We are developing a graphics editor to easily draw Braille-embedded tactile graphics for scientific documents including mathematical expressions with Infty specialized system. Each graphics embedded in a document is cut out and characters on the graphics are recognized by InftyReader. The recognized graphics can be edited with this graphics editor, which is based on scalable vector graphics. Since, in the editor, ordinary texts and mathematical expressions on the recognized graphics are presented by InftyEditor, users can easily edit them with its input interface. After completing the edit process, all texts and mathematical expressions are automatically translated into Braille by our original Braille translator, InftyBraille. Then, the edited graphics is output as an EMF file. Embossing out the EMF file, users even who do not know Braille codes can get a Braille-embedded tactile graphics.
