Other communication systems and resources

tadomaTHERE ARE OTHER COMMUNICATION SYSTEMS used by Deafblind people in other countries that correspond with the variations inherent to the country in which they are developed or systems that are used by one person and what exceed the content of this text. It is important to make a brief mention of the Tadoma although it is a system used by very few Deafblind people, but that is characterized by gathering information through vibration.

Tadoma is a method for learning to speak by means of vibration but some Deafblind use it as a method to understand other people speech.

Deafblind adults or children who are being taught with Tadoma method, must place a hand (or two at the beginning) in the face of the speaker. Put their two thumbs lightly on the lips and and their little fingers along the mandible bones, and the remaining fingers on the cheeks.

The vowel sounds in air come from the lungs through the vocal cords and find their way outside, without any obstacles, through the mouth. The difference between a vocal sound and another is achieved by opening the mouth more or less and changing the position of the lips.

The consonant sounds are generated by interrupting the output of the air with the lips, tongue and teeth. The classification of our consonant phonemes can give us an idea of the information that the child receives with the hands on speaker’s mouth, cheeks and jaw.

It is an interesting method to study, as a mean of speech development. As a communication system is complicated because in addition to the need for a great skill to touch discrimination, there is a difficulty that the speaker is not used to allow placing other hands on the mouth.


AIDS technicals and new technologies, even not being proper communication systems, offer a number of technological resources that allow the access to the remote communication by the Internet through the use of computers, tablets, mobile phones, smartphones, etc., suitably adapted with the necessary adaptations in each case to Deafblind people.lineabraille

Depending on the sight and hearing remains and the main sensory channel for access to the information (sight, hearing or tactile -braille-) may share information and communicate from a distance with the rest of society, and depending on the possibilities that sight allows, through the textual or signed communication.

We will find ourselves in communicative situations where adapted technology may be a very suitable tool for the transmission of information and a useful resource that allows the communication with Deafblind people. Each day we find more communication resources for Deafblind people thanks to technology advances and the accessibility to them.
