Résumé :

In the growing market of camera phones, new applications for the visually impaired are nowadays beingdeveloped thanks to the increasing capabilities of these equipments. The need to access to text is of primary importancefor those people in a society driven by information. To meet this need, our project objective was to develop a multifunctionalreading assistant for blind community. The main functionality is the recognition of text in mobile situations butthe system can also deal with several specific recognition requests such as banknotes or objects through labels. In thispaper, the major challenge is to fully meet user requirements taking into account their disability and some limitations ofhardware such as poor resolution, blur, and uneven lighting. For these applications, it is necessary to take a satisfactorypicture, which may be challenging for some users. Hence, this point has also been considered by proposing atraining tutorial based on image processing methods as well. Developed in a user-centered design, text reading applicationsare described along with detailed results performed on databases mostly acquired by visually impaired users.
