Access to Information for People who cannot See: New Perspectives

Access to electronic information and services for people who cannot see is achieved at present through the use of screen reader or other transduction technologies. Applications are commonly equipped with a reference interface, which is generally graphical, that has to be translated into a form that can be perceived by means of different sensorial channels, so that users with forms of access limitations are able to interact with them. In view of emerging technological scenarios. this approach could reveal limitations and systems could be designed in such a way that an application core capable of performing elaborations on certain information contents can be accessed by different modalities that can be easily plugged to form a flexible multimodal interface that enables interaction for all people.
