  • I'm curious to what you all think of this:

    No, we're not referring to your beloved Atari Pong paddles -- we're talking about your brain. The EPOC uses a headset that actually picks up on your brain waves. These brain waves can tell the system what you want to do in your virtual reality. In other words, you think "lift," and a virtual rock actually levitates on the screen.

    How the Emotiv EPOC Works

    Magic or nah?

    • Not magic, of course. It's science.

      The elctrical activity in your brain is measurable by electrodes placed on your skull. What we then get is called an electro-encephalogram, short: EEG. Although they rather measure a summation of activity rather than individual neurons. Still, this allows to draw some conclusions and has been widely used in neuromedicine.
      For instance, it can help to diagnose epilepsy, or investigate sleep quality. In contexts of the Emotiv, to put it simply, it rather measures levels of concentration than actual thoughts.

      But, with sufficient training you can enable such a system to perform a bit more complex tasks, like opening or closing a mechanical hand, driving a wheelchair in a simple mamner, etc.. Although, from my experience, the applications are very limited and unstable.
