A few days ago, I was introduced to Neurosky’s brain-computer interface technology. In essence, Neurosky’s unit senses brain activity noting general levels of attention and meditation. The unit then translates this activity to move objects in the real world or in a game on a computer screen. Yes, that’s right. You can finally move things just by thinking about it.

Here’s the long and short of it. The user wears a headset that looks very similar to a common pair of headphones. The technology uses what’s called electroencephalography to record brain signals. In the common medical sort, a conductive gel is used to facilitate the collection of these signals. In Neurosky’s case, they use one patented dry-active sensor for getting the job done.
