Current interactive multimedia learning software can not be accessed by learners with disabilities. This is the case for students with vision disabilities. Modeling techniques are necessary to map real world experiences to virtual worlds by using 3D auditory representations of objects for blind people. In this paper we present a model to design multimedia software for blind learners. The model was validated with existing educational software systems. We describe the modeling of the real world including cognitive usability testing tasks by considering not only the representation of the real world but also modeling the learner’s knowledge of the virtual world. Finally, we analyze critical issues in designing software for learners with visual disabilities and propose some recommendations and guidelines.
