‘Close’ is an attempt to an alternative system, to provide speech input for deaf/ hard of hearing through tactile sensations.
With similar characteristic as a smart watch, ‘Close’ sends electrode arrays to the wrist- giving a feeling of touch. The designers involved believe that the brain can then decipher these feelings into speech patterns.
I can’t imagine that the brian will learn to link these vibrations to speech. It would take a considerable amount of time for the wearer to train themselves to decipher from one vibration to another.
When at a music festival for example, you can feel the vibrations through your feet on the floor from the heavy sounds of the instruments and voice. How could speech be translated? Surely the vibrances will not be enough to understand the content.
Would be keen to try this design or speak with someone who has tried it.
