Alphabetic communication systems
They those which rely on the spelling of the message. Most commonly used by Deafblind people oral language users, and sight and hearing difficulties do not let them receive and understand the message by the hearing channel, and neither leaning or understanding it through the visual channel through lip-reading.
Videos: Different alphabetic communication systems, based on the spelling of the message, used by the Deafblind people from different countries.
The alphabetical systems are the most indicated to communicate with blind people who lose their hearing and in general for all those persons who acquired the Deafblindness being the oral language their regular communication system, because being blind acquired hearing loss or even being deaf commonly used the oral language to communicate, both expressive as responsively (lip-reading).
In Spain the most used alphabetic systems by the Deafblind people are:
Is to talk through changes in position of the fingers that are accompanied by slight movements of the hand. Each letter has a shape that is made on the palm of the hand of the Deafblind person. For a long time was known as a communication system for Deafblind par excellence because it was used by Anne Sullivan to teach Helen Keller.
The current alphabet with a few variations was introduced by the Spanish Juan Pablo Bonet in 1620 for use in the education with a deaf person. In the tactile version for Spanish Deafblind people fits each one of these configurations for the reception on the Deafblinds’ hands.
Allows the complete transcript of the message, letter by letter, with the same linguistic structures of the phonetic oral code. It is an analytical method that requires a good capacity for synthesis to integrate the word and good ability to touch discrimination.
This system presents different variations in each country, as well as for example we can find the LORM alphabet, (used in the Czech Republic and some German-speaking countries), the MALOSSI, (Italy), two-hand alphabets (England, Denmark, etc).
Consists of writing with the index, in the middle of the Deafblind person’s hand palm, each one of the letters comprising the words in capital letters, one above another.
It is the most useful system to communicate with people who have acquired the sight and hearing impairment during the course of life. It is usually therefore a first communication system for people knowledgeable of the oral language and that late visual loss due to know the spelling and the visual form of the letters of the alphabet. In addition, for these Deafblind persons this system implies a very useful resource to communicate with the rest of the hearing society and the public in general.
THE FINGER AS A PEN
The index finger of the Deafblind person is taken and is written with it, as a pencil, the message that you want to transmit. It can be in the air or on a surface.
It is the first way of communicating with people who become suddenly Deafblind.
