Mobile application model for the blind

Abstract

This study presents a model to design and implement mobile applications to support the displacement and dynamic decision making of users with visual disabilities. To identify the real added value of using mobile technologies as support aids for decision making in dynamic contexts for users with visual disabilities, we provide an application case. By using a graph to represent the computer model of a real school for blind children, for whom a system was already developed using our model, we provide a real example application of this model. This provided enough input to enrich, improve and redesign the model; ending up with a usable mobile application model to assist the mobility and orientation of blind users. © Springer-Verlag Berlin Heidelberg 2007.
