With the growth of modeling activities in software development processes, the participation of visually impaired users requires dedicated e↵orts so that the models are capable to be understood, otherwise this participation is compromised. The models are mostly visuals and, therefore, their construction process requires the positioning of elements in the document space with a pointing device, like the mouse, and their reading requires the use of vision, since the diagrams are composed not only by text, but also by visual elements such as rectangles and arcs connecting them. In this context, the goal of this project was to develop a textual technique to represent and interact with diagrams to allow visually disabled people to collaborate in software development projects, either using an model driven development approach or a tradicional development approach. To achieve the proposed goal, a prototype Web tool called AWMo was developed. The prototype allows the edition of models to be done in two distinct views: a graphical view, where the software engineer is able to insert new elements and define their position in a visual and traditional way; and a textual view, where the software engineer is able to insert new elements, their properties and relationships using a textual grammar. A case study was conducted to evaluate the e cacy of the approach and the results show that the textual language developed did not posed itself as a barrier to the use of the AWMo. The results suggest that AWMo is a viable option to allow the access of the visually impaired to software models, promoting collaboration and e↵ective communication between sighted and blind users in software modeling activities, but most importantly, in an independent way.
