Abstract
How to design and generate tactile graphics that have clear semantic meaning and are easy for visually impaired children to recognise using their sense of touch in special education is currently a challenge in China. This study summarises the advantages and disadvantages in different technologies for tactile graphics generation by analysing 12 papers in the last ten years on tactile graphics in education field. The insight from this work will help researchers, design professionals, visually impaired children and educators in China to make informed decisions about what they should focus on, how they should do it, and why they should do so.
