Introduction: Three-dimensional (3D) printing can be used to produce tactile teaching materials for individuals with visual impairments. Although 3D and 2.5D teaching materials are based on realistic content, no systematic conversion model for 2D materials exists. Here, we combined the previous findings and this study's results and technology to…

Diagrams appear in many school subjects but more prominent in science and mathematics taught in schools. Accessing these diagrams in an inclusive classroom has been identified to be problematic for blind students partly due to the teaching resources available and personnel type, support and sufficiency. Diagrams are mostly omitted by teachers…

Diagram describing texts are integral part of science and engineering subjects including geometry, physics, engineering drawing, etc. In order to understand such text, one, at first, tries to draw or perceive the underlying diagram. For perception of the blind students such diagrams need to be drawn in some non-visual accessible form like tactile…
