Working on it...
There are a variety of bioelectric potentials that convey information through
the body, EEG being one of them.  EEG's are extremely complex and are difficult
to analyze in real time, though there are promising techniques for doing so.
You can also measure the potentials from peripheral nerves and muscles which
are prefiltered and amplified to be more suited to their specific (often motor)
action.  Evoked potentials suffer from the fact that your body adapts to 
continuous stimuli and that the process of evoking them can be annoying to the
subject.  I'll post more when I get some better data.
