In the Internet world, the widespread use of graphical user interfaces (GUIs) increasingly bars visually handicapped people from accessing digital information. In this context our project aims at providing sight handicapped people with alternative access modalities to various types of GUIs and graphic intensive programs, in order for instance to facilitate usage of Web services. We describe in this paper AB-Web, a 3D-audio Web browser that allows blind computer users to explore Web pages, fill in forms, etc., using a 3D sonic rendering. We also present WebSound, a generic tool that permits to associate with each HTML tag a given sonic object (earcon or auditory icon). Finally, we describe a series of associated programs composed of the family of sonic games From Dots to Shapes, as well as of IDEA, a tool that lets users comprehend simple drawings, as well as to create graphics.
