Blind or visually impaired persons as well as persons suffering from severe motoric impairments face various problems when it comes to independent travelling. This paper will shortly review the state-of-the-art technical solutions and show what future improvements could be achieved by using up-to-date technology like GPS (Global Positioning System), optical 3D scene analysis or digitally stored maps. The paper is also a call for European R&D cooperation to make these new technologies available to disabled users as soon as possible.
