Flowchart content descriptor for visually disabled people
Amaia Méndez Zorrilla, Begonya García-Zapirain, Ibon Ruiz, Alvaro Muro · 2009
The graphical information used in technical degrees is not accessible to visually disabled people, which is why a system is being developed to provide a textual description of the information from diagrams using digital image processing and computer vision techniques. This data is used to create a textual description which will be automatically added to the corresponding figure in order to make it accessible. Lecturers and teachers will be able to create teaching materials with common applications such as DIA, and then they will convert the charts into accessible-content figures in a very easy way. When the material arrives to the students, they will be able to access the information with the usual general applications like OpenOffice. The screen reader will let them navigate around the graph in order to access the information of a concrete element in it.
