This is one of my older concepts gathering dust in a notebook from years ago. Which it would bring joy to my eyes to see something like this so that those handicapped by blindness and deaf can play music we all can enjoy. (besides fulfilling the mission of this blog site)
Many of you will be scratching your heads saying "huh?". A musical instrument for a blind and deaf person to write or play existing keyboard music. Well, the suggested solution is very simple really. Besides converting a musical instrument like an electronic keyboard with Braille keys. Have the keys for the deaf have a kinetic type of force feedback haptic pressure. Where each musical key in relation to its sound would have a different sense of pressure to the key. Somehow wiring an air-pump with an electronic musical keyboard with Braille keys.
So that a blind or deaf person can play music at least on a piano-like instrument. The musical tones coming out of the device can still be the same so everyone can enjoy the music. Otherwise, if air pressure isn't a suitable method for such a musical instrument. It could employ a decibel vibration to each key so that the blind or deaf musician can actually feel the music they're playing.
Where in the case of a decibel vibration method to an electronic keyboard. The output of the music can be toggled from traditional sound to include a form of music based on decibel vibrations acoustically speaking.
