Design and Evaluation of an Accessible Mobile AR Application for Learning About Geometry

Augmented reality is currently a very interesting technology due to the possibility of wide use on various affordable devices and at the same time high engagement and motivation potential for the user. These features are especially important in the educational field. As the number of developed prototypes in this area is rapidly increasing, only a limited part of them considers the implementation of accessibility, although accessibility is strongly required especially in educational solutions. The paper presents accessible mobile application for learning about geometry, specifically about geometry bodies, and this topic is often a challenge for children with learning difficulties. In addition to the accessibility option implemented, the actual design of the best-known universal design principles within the application is described, as accessibility relies heavily on them. The results of the application evaluation are presented, leading to the conclusion that this and future AR software solutions have great potential to be included in the curriculum as a tool for inclusive education, but only if the concept of accessibility is properly understood applied.
