Assisting the mobilization through subway networks by users with visual disabilities

We introduce AudioMetro, application software for blind users that represents a subway system in a desktop computer to assist mobilization and orientation in a subway network. A user can organize and prepare a travel by using the software before riding the subway. Conclusions of the usability study revealed the critical importance of using key interface elements, such as audio-based hierarchy menu, travel simulation, and information about the subway network, stations and their surroundings. Cognitive study results show an advance in the development of mobility skills needed for using the subway system which represent a contribution for a much more integral development of blind users and one-step towards social integration and inclusion.
