after my initial successes, i then rebuilt the demo with 8 LEDs and cleaned up the wiring to stabilize all the hardware and add additional response range. i practiced for the next couple of hours to develop some control over the system.
i am seriously impressed with the response can already trigger. i realize that this is a simple graphing of one metric in of the EEG profile, but i have already experienced several characteristics of the biofeedback system that are noteworthy.
- it is hard to hold it at a level for a long period of time. i assume this kind of mastery will come with more experience. i can already light the rig with more control after just two hours of practice.
- abstraction is helpful - ironically it is easier to concentrate on the video image of the LEDs and get an active response. i am not sure what is at play here exactly but i theorize that when i look at the actual LED array, i also need to visually process the surrounding world and thus distractions are more plentiful.
- biofeedback - any self imposed distractions (holding my body awkwardly, tensing up, straining, etc.) actually limits my control. it is very meditative. A musician friend made a conjecture that such feedback could help in voice training so people could monitor the tension in their bodies. Very Jedi indeed.
