Who is organizing?

The CIDAT is the Reference Centre for Research, Development and Implementation of Technical Appliances in ONCE, regarding assistive devices and technologies for the blind and visually impaired.

It is the area within ONCE responsible for managing the production, acquisition, distribution and maintenance of specific devices for the blind and visually impaired, and for supplying all necessary resources for adaptation of work and study stations. Besides, it coordinates all research activities, development, guidance, design and manufacture undertaken within the scope of assistive technology at the institutional level.

The rapid increase of Information and Communication Technologies has brought about such a substantial swift in society that people’ personal and social development depends heavily on the skills they possess when handling these technologies.

However, a large number of the technological devices on the market  is not likely to be easily used by everyone, and requires adaptation to avoid posing a factor of disadvantage or segregation for certain sectors of the population, since universal design has not been taken into consideration in their development, which specially affects to people who are blind or visually impaired.

On the other hand, the implementation of technology means an ongoing source of solutions for these persons in the many different areas of independence and wellbeing: daily living,  mobility, education, employment, leisure, culture, and so on.

In order to obtain the maximum benefit from the application of technologies, ONCE actively operates in all its national care network and from CIDAT, Center where the following activities are carried out.
