“…From an educational viewpoint, the 2D mobile braille display can be beneficial for obtaining information such as scientific figures, natural scene images, literature, and audio-based education [66]. Kim et al [31] concentrated on the development of a 2D multi-array braille display utilizing an electronic book translator application because of its accuracy and high speed. To share multimedia content, they presented a braille electronic book reader application that could share a large number of figures, text, and audio content.…”

“…The system facilitated the automatic conversion of images to refreshable braille displays, enabling the authoring and real-time distribution of education materials to BVI students. Kim et al [31] proposed a 2D multi-array refreshable braille display utilizing an electronic book translator software because of its accuracy and high speed. The procedure was versatile and applied a 2D multi-array refreshable braille display to represent media content and shapes.…”

Currently, a large amount of information is presented graphically. However, visually impaired individuals do not have access to visual information. Instead, they depend on tactile illustrations—raised lines, textures, and elevated graphics that are felt through touch—to perceive geometric and various other objects in textbooks. Tactile graphics are considered an important factor for students in the science, technology, engineering, and mathematics fields seeking a quality education because teaching materials in these fields are frequently conveyed with diagrams and geometric figures. In this paper, we conducted a systematic literature review to identify the current state of research in the field of automatic tactile graphics generation. Over 250 original research papers were screened and the most appropriate studies on automatic tactile graphic generation over the last six years were classified. The reviewed studies explained numerous current solutions in static and dynamic tactile graphics generation using conventional computer vision and artificial intelligence algorithms, such as refreshable tactile displays for education and machine learning models for tactile graphics classification. However, the price of refreshable tactile displays is still prohibitively expensive for low- and middle-income users, and the lack of training datasets for the machine learning model remains a problem.
