Accessible Augmented Reality to support chemistry teaching

Learning technologies are innovating the Education, offering resources that enrich the teaching-learning process. Among the various resources offered, Augmented Reality (AR) stands out, where real and virtual worlds are mixed. However, AR brings visual-based interactions only, blocking any experiences from students with visual limitations. Therefore, this work explored the accessibility guidelines in order to match the experience of a visually impaired user with a non-impaired user while interacting with AR. Thus, to verify if this is possible an AR application, Accessible Chemistry, was developed. Based on assisted technologies, it aimed to teach concepts of atoms connections and compounds formations to students with low vision. Finally, a predictive evaluation was made to validate it"s accessibility.
