Step 2A little more
this is a simple way of mapping other information onto your existing senses. In this case, you're sensing magnetic fields through your sense of touch.
Somebody did a cool research project with a similar setup, trying to help piano students develop muscle memory for songs. She used electromagnets on her subjects fingers, and put electromagnets in piano keys, and would turn on the right combination of electromagnets--like c# and index finger, to encourage the subjects' index fingers to hit the C# key.
Some other sensory mapping stuff that's more advanced (just regurgitating things I read in tech blogs)--
Someone came up with a navigation system for the blind that would generate smells based on a sonar system that would detect how close obstacles were.
Someone else let blind people see by stimulating nerves in the tongue.
Anyway, this is cool stuff. Play with it!
