See topic.
I have recently gotten curious about these things since suffering a nerve injury. I healed after 3 months or so but I am still curious about the things. I can see them having some applications (aside from being disabled) in the automotive industry or on motorcycles.
If anyone can talk to me about using/learning one please post here.
