The deaf-blind can now 'watch' television without intermediaries

A new device, PervasiveSUB, compiles all the subtitles of television channels and sends them to a central server, which forwards them to smartphones or tablets.

From there, they are sent to the Braille line of the deaf-blind thanks to an called GoAll, which integrates the software, and is compatible with different Braille lines and makes it possible to control the speed of the subtitles that are captured directly from the TV broadcast in perfect synchronization.

The presentation, which took place at the Universidad Carlos III de Madrid (UC3M) at the Madrid-Puerta de Toledo campus, was attended by Ángel García Crespo, a UC3M professor and director of the project; Arancha Díaz-Lladó, the director of Telefónica's Sustainable Innovation; and Francisco José Trigueros Molina, the president of FASOCIDE.

UC3M is a Spanish university, ranked among the 20 best universities established within the last 50 years, according to the annual QS ranking.

Also in attendance was a group of deaf-blind persons who gave a demonstration of how this technology works.

PervasiveSUB, financed by Telefónica, was developed by the research group at the UC3M Pedro Juan de LastanosaInstitute of Technological Development and Promotion of Innovation. García Crespo, who headed the group, stated that "one of the big problems deaf-blind persons face is the scant attention they receive, which is demonstrated by the fact that they weren't recognised by the European Parliament until 2004."

Díaz-Lladó said, "At Telefónica we endeavour to become a more accessible company and that way contribute to equal opportunities for all. And although we still have a long way to go, the new inclusive technologies and the digital revolution are the best means to help us get there."

A group of deaf-blind users from FASOCIDE was asked to try this innovative software in Spain and the United States, with very satisfactory results. All the people who have tried it highlight the advantage of being able to access information they previously could not, in real time and without intermediaries, and they have also praised its ability to transmit to Braille lines and the ability to adjust the reading and viewing speed.

Given the success of these tests, the technology has already been implemented on all the national DTT channels and regional DTT channels in Madrid, and it will soon be available in the other autonomous regions of Spain. The research team is now providing this service free of charge to anyone who needs it. Interested parties need only to download the GoAll app, available on ¡OS and Android.

Deaf-blind persons suffer a combined deterioration of sight and hearing, which impedes their access to information, communication and mobility in a way that seriously affects everyday abilities necessary for a minimally independent life. This is why they require specialized services, personnel trained specifically to care for them and special methods of communication.

In Spain, there are around 20,000 deaf-blind persons. To interact with their surroundings, they need an interpreter through whom any visual or auditory stimuli must pass.

However, from now on, and thanks to research of the sort done at UC3M, they will be able to receive television broadcasts first-hand and directly in real time and in the same conditions as everyone else.
