Towards Establishing a Description Standard of Mathematical Function Graphs for People with Blindness

Visual representations are widely used for conveying information for sighted people. However, these visualizations are often inaccessible to blind people, requiring special adaptations. Especially in higher education, it is vital to support the learning process how to explore graphics. Although the description of graphics is a solution to make them accessible, there are only few standards for descriptions for this target group. In this paper, we develop a standard for describing function graphs at the university level in a user-centered multi-stage design process, focusing on structuring the information for blind readers and guiding authors to include necessary details to avoid errors.
