“…Some researchers raise the issue of ambiguity convert between LATEX and MathML notation [34]. Additionally, another report that TeX does not provide an encoding of the semantics for the mathematical material and this information must be derived from some (external) context [3]. Due to this fact, to guarantee high quality of education materials, we decided to avoid automatic conversion to alternative text description.…”

Nowadays, the math learning is an important step in developing professional carriers in technical and economic sciences. Increasing the number of e-learning tools used in universities courses can reduce the potential barrier of access to mathematical knowledge, but most of them are not accessible for impaired students. Moreover, classical printed math books include little explicit instructional information about structural information interpretations. Taking into account these barriers the article presents the developed method used for creating interactive steps of decomposed math's exercise solution and alternative description of math formulas accessible for the blind. The elements of proposed methodology: generation of state machine, design and presentation of transition conditions, generating the presentation layer and a typical usage by a blind user are presented. A set of rules for describing mathematical formulas were proposed after consultation with mathematicians and teachers of blind people. The application was developed as web application. The graphical interface of presented application was designed using PHP and JavaScript technologies. The collection of prepared exercises include about 240 prepared exercises from different areas of mathematics Multimed Tools Appl (2018) and 60 selected exercises including alternative description layer. About 1000 students and about 40 impaired students, from 6 faculties of the university use this platform during math courses for both self and class learning. The defined rules were used to read aloud mathematical formulas to the visually impaired people with a different level of mathematical knowledge. The results confirmed good understanding of mathematical formulas by using prepared alternative description.

“…It uses sophisticated graphics and interaction techniques that are accessible for visually impaired children. An intelligent tutoring platform called "The Project for Math" [25] offers an interactive system for supporting mathematical education. It is based on a collection of exercises for students who want to study particular mathematics skills independently (i.e., mathematical formulas, structural information of mathematical expressions and equations) and can be used to enhance their knowledge.…”

Although smartphones are equipped with accessibility functions, they still pose significant problems for visually impaired people. Sometimes these functions cannot fulfil the expectations of users. Early mobile devices had physical buttons and a keypad, and visually impaired users could navigate around the keypad using the tactile markers on the buttons. However, the lack of tactile markers makes it much more difficult to operate a touchscreen device. This paper describes an e-learning platform that is designed to improve the accessibility of smartphone applications for students who are visually impaired but have some useful vision. A User-Centered Design approach was used to develop an effective solution for visually impaired students. A study was conducted during the development of the described platform, and the results showed that our suggested design improves task completion time as compared to the initial version. Participants also expressed higher levels of satisfaction when using the improved design of this platform. The modified design was also assessed using the Mobile Application Rating Scale (MARS), and the results indicate that it is quite reliable and rated well among visually impaired children. Furthermore, developers can use our suggested design guidelines such as clear navigation, color contrast, immediate feedback, icon arrangements, button and text size in the development of new applications.

“…This approach ensures that blind people receive full support in the learning process and have access to educational content adapted to their needs, enabling their development in areas such as mathematics and other STEM subjects [31]. Taking into account our previous experience in designing solutions for individuals who are visually impaired [32][33][34] and many consultations with blind students and their teachers, we also attempt to merge a user-centered design approach with our solution.…”

Teaching mathematics to blind people is a challenge of modern educational methods. This article presents a method of preparing the adapted material and its usage in the learning process of mathematics by blind people, as well as the results of evaluating the proposed approach. The presented results were obtained based on a mathematical analysis course conducted in two classes—with and without using the developed method. The developed method uses the conceptualization of knowledge as a graph. The learning process is supported by feedback processes that consider the mechanisms of knowledge and error vectors, on which a personalized adaptation of the learning path is made for each particular student. The evaluation process has shown a statistically significant improvement in learning results achieved by blind students. The average final test score in the group working with the platform during learning increased by 14%. In addition, there was an increase in cooperation between blind students who had the opportunity to take on the role of a teacher, which was observed in 27% of the participants. Our results indicate the effectiveness of the developed approach and motivate us to evaluate the method in a broader group of students. The engagement of students indirectly indicates overcoming the barriers known from the state of the art: uncertainty, poor motivation, and difficulties in consolidating the acquired skills.
