Good post J3RK.
Universities are also a great source for this sort of research and specialization.
I posted this a while back about a prosthetic that allowed individual finger motion done at Georgia Tech. There is quite a lot of this sort of thing done at universities.
Here’s the video.
Don’t get hung up on the current state of the technology, key in more particularly on the reaction of the participant here, and picture what these sorts of things can mean longer term for this person and others.
Also there are schools that focus very particularly on the individual, and find ways to get there, regardless. For instance The Academy of Music for the Blind (AMB) in the Los Angeles, CA area. They aren’t the only school, there are others around the world, and there also are many individuals that are doing the same sort of individual instruction, and getting into the heart of music creation.
ADDED : Another video from the same group at Georgia Tech, with a bionic drummer prosthesis. Another source of funding for this sort of creation, money from the Defense Department for help to veterans.
