Impact
The development of a AA Accessible Street Directory applying Geographical Information System technology is very complex. To develop a Street Directory usable by a blind is a challenge. In a regular web site AA, the textual information is organized according to the standard AA in the way that text can be read through specifics programs (Yaws for instance) and understood by the blind.
The development of AA Accessible Street Directory is quite complex. The information is geographical, numeric and graphic, and we have to transform it to a textual description. For example, if a blind wants to know the address of a restaurant and the public transportations to go, the system has to find the restaurant, locate the address in the map and through spatial analysis find all the entities of interest, in this case the public transportations (bus and underground). After that, the system has to transform the graphic information (the map information) in textual information under the standard AA to be read vocally.
The innovation of this project has been the ability to transform geographical information into textual information and the way in which the system allows to move through the map without using the mouse.
The benefit of such technology is that we can build all kinds of Geographical Information Systems usable by disabled and blind people, facilitating their social integration
Track record of sharing
The project has been developed as initiative of the Municipality of Madrid and with our own budget. The analysis of the application and the requirement catalog has been developed by technicians of the municipality. The development of the system has been carried out by Indra Sistemas, a Spanish company in the field of TI.
The project has received the TAW award (Test of Accessibility Web) to the Best Accessibility Web Project, an important award in Spain.
The system has been showed in several IT congress. We are open to show the system at a technical level to any Spanish or European corporation. In fact, some projects of the same characteristics are being developing by our technological partner for other institutions in Spain.
Lessons learnt
The project was considered in the beginning as a research, due to the technical difficulty and that we did not know any other Internet project with this specifications. We constituted a group to consider the viability of the project and to resolve issues. As a result, all parts involved have acquired an important knowledge about the technology needed to build a geographical information system accessible even for blind people. Now, we are applying this technology to other projects using geographic interfaces.
