Vibrotactile Aids
<languages /><translate> Vibrotactile aids, as the name suggests, are mechanical instruments that help individuals who are deaf to detect and interpret sound through the sense of touch.
How do they work?[edit]
Vibro-tactile uses one of the natural senses – touch – to convey meaning. A child or person without hearing or who has very little residual hearing will turn to the source of vibration or even air movements in his or her environment. Vibro-tactile senses can be increased through the use of Vibro-tactile aids that convert sound into vibration patterns.
Use with other communication methods[edit]
Vibro-tactile devices are sometimes used to train children to attend to the presence of sound in their environment. Our sense of touch and sensitivity to vibration is not an efficient replacement for the high discrimination ability of human hearing or sight. Vibro-tactile is a technique used with other communication features, and not as a standalone communication method.
Neuronal mechanism[edit]
Neurons in the primary somatosensory cortex (S1) react to vibrotactile stimuli by activating in synchronization with each series of vibrations, giving the person person of the stimulus or sound indirectly.
