Currently, digital documents from all backgrounds use a rich, sometimes complex formatting, which makes their access difficult for the blind. The existing tools and techniques aimed at making these documents accessible do not take into account the original formatting of the document, which nevertheless carries a lot of relevant information. The objective of the project is to design tools to increase accessibility digital documents for the blind, making this visual information relevant. The project is being carried out as part of the study of mathematics programs. This is based on the establishment of an annotation method and model allowing the description of the visual information of the document and then developing an audio-tactile access of these documents.

General objectives

  • Design an annotation method and model allowing the formal description of the visual information given by a document
  • Develop audio-tactile access strategies for annotated documents.

Operational objectives

  • Establish a DTD, that is to say a set of annotation relations: vocabulary and annotation method for an annotated corpus to finally lead to an automatic annotator
  • Develop a document reader allowing to restore annotated information in a non-visual way
  • Evaluate the effectiveness of multiple prototypes using different information presentation and navigation strategies in annotated documents
