Visual representations, such as graphics and shapes, are modes of presenting information that can pose a challenge for individuals with visual impairments. To address this issue, mobile technologies that provide tactile and auditory stimuli have been developed to ensure equal learning opportunities for individuals with visual impairments. The…

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…
