Its research activities are related above all to technical, but also to pedagogical and social issues. The main emphasis is on problems arising in relation with the learning and working situation of visually impaired people in the course of their university and job life. Moreover, the SZS is engaged in various other research activities, such as developing a standardised mathematical script for the German-speaking area and establishing a ubiquitous mobility and information service for the blind. In addition to its co-operation with various institutes of the KIT, the SZS also maintains a close co-operation network with universities world-wide, especially in Central and Eastern Europe. In this regard, we participate in projects funded by the EU, such as "Youth for Europe", "TACIS" and "EQUAL". Lately we have increasingly established new partnerships with universities in Asia and South America.
