But I'd looking for real books or at least a talking-book.
The best should be to find them in italian.

The project is leaded by Michel LUCAS, maybe you can contact him by O-List.The Aveuglami Project (in french : Aveugles et Origami, which means Blind people and Origami) is devoted to the teaching of origami to Visually Impaired people. It started in september 2004. Some major points about Aveuglami today (2009) :
- around 20 visually impaired people attend origami workshops. They learn to fold very different models, from basic to modular ones. Some of them have become true folders, and create their own production, essentially through the use of modular origami.
- texts have been produced (called Diagram Free Folding (DFF) scripts) for more than 150 models. These texts are used as reminders, in order to help people to fold at home, without a teacher. They use these texts during the workshops, so that the vocabulary becomes familiar and understandable.
- braille printing is usually produced, for those people able to read braille. - some blind folders are used to teach origami to people attending to exhibits or workshops.
- experiments in teaching geometry to young blind children using some origami stuff have been achieved. The results were really impressive.
