Deafblindness - congenital or acquired at an early age (before language acquisition), blindness and deafness, to which is added the lack of hearing loss associated with dumbness. In this case, one can not "replace" the lack of hearing and vice versa, which causes a lot of problems: children do not develop and do not acquire the basic skills of self-service, if you do not work with them using a variety of techniques and equipment.
How to communicate with deaf-blind? How do they orient themselves in space? What devices help them in this? Read more - under the cut.
Communication h4> To begin with communication with the teacher. Blind hear it, the deaf use gestures and lip-read. If both of these feelings in humans are absent at the same time - is the sense of touch. In the 1940s, IA Sokolyansky has developed a system to transmit information from teacher to student: it teletaktor. The teacher presses a key device, and a student reading a message on Braille. Later, there was another problem - how to transmit information to several students, a whole class of children? In 1966 he began to use an improved version of teletaktora, but still with a one-way communication - "daktilyator."
In the process of learning always need two-way communication. This call took VV Lebedev, and developed teletaktor positive, negative and mutual communication - "TEPROIVS."
Other apparatus for transmitting messages to a group of students created MM Germany, he used klavituru similar to a typewriter. Special recode device made it possible to communicate with deafblind people who do not have special skills to communicate with them. In 1968, he developed a class with positive, negative and mutual coupling, but the device is issued only one letter at a time - each word had for a long time to print. Three years later the problem was solved by using the new version teletaktora with tactile display, showing 24-point mark in relief.
Social Network h4> How deafblind receive information from the Internet? Speech synthesizers convert the data not only in sound, they can work in Braille. Special "screen" allows you to read information with your fingers. Set of raised dots rises and falls in the correct sequence. The system has drawbacks. You can not see the picture, it is impossible to determine the value of the information on a web page - have to read all the text from left to right and top to bottom, and never will work with tables. Wherein the plurality of pages contains data that can not be translated into text. Navigation mouse - useful for sighted people, but for the blind and deaf-blind need to make a special version. Or create universal methods for interaction. Solutions to these problems open market for developers of technical means of rehabilitation for the blind and deaf.
Mac OS has built-in features for people with problems with vision and hearing. Computers and mobile devices from Apple is working with 40 different braille displays.
This special display works in conjunction with a computer. Apple is working with a number of such devices, as I noted above.
