Abstract
A system is presented enabling blind people to understand and fill in printed forms. Text and graphic components are separated from each other, the first one presented by a Braille-line or alternatively via synthetic speech and the second one by a special swelling paper supplemented with markers for text events and markers for recognized fill in places. Furthermore a new method for the interpretation of complex structured images is described, which is used in the application mentioned above. This method takes advantage of a compositorial hierarchy of objects to be recognized and makes use of models given as relational structures. A convenient language for model formulation is introduced. First results are demonstrated.
