It seems the OCZ device is bogus. http://www.ocztechnology.com/products/ocz_peripherals/nia-neural_impulse_actuator

Doing further investigation provides proof that there is no SANTA. This too is not
something that will be coming down the chimney any time soon. It seems that the device
detects facial muscle movement produce IT results. I can't see someone making funny
faces for the purpose of instantiating computer interaction. I hope EPOC will do better when
they release.

I have looked at both sites you have posted and must say that I am intrigued at the
potentials this technology may be able to provide. I am investigating aids to disabled
persons and this sounds like a another pathway (beyond the senses) that may someday
provide significant benefits to those affected.
      You mentioned that you had some experience with the currently available
technology. Can you elaborate?
      I have reached out to the two organizations you provided and hopefully will be able
to gain more insight.
