Making Linear Equations Accessible for Visually Impaired Students Using 3D Printing

Due to the limitation of the available tools that enhance math education for visually impaired students, this paper proposes the design of an authoring tool that helps math teachers produce accessible learning materials for linear equations in the form of 3D models. The proposed tool will focus on producing 3D models of linear equation graphs printed in predefined plates with proper Braille captioning.
