It may sound like science fiction, but using your brain waves to control the environment around you, like the lights in your home or even your toaster, is already a reality.
One Toronto-based company has developed a system called thought-control computing and it's exploring a range of commercial opportunities that include screens on airplanes and video games.
Its philosophy is simple: If you can plug it in, you can control it with your brain.

I've heard of this..
Although, doesn't thought control usually refer to people's minds being controlled, not the other way around?
It's the thought that counts.
We are in the realm where science seems like magic. A person hooked up right, just by thinking, can turn on the lights in a house or start other machinery. Can this technology by used in assembly line production or high skilled work- the ultimate CAD? Waldo's doing surgery according to the surgeon thoughts? in aviation or other forms of transport, just by "wishing" you turn the ship. Can you kill by a thought?

Monkey Moves Computer Cursor by Thoughts Alone, By E.J. Mundell
Any control of brain wave rhythms have physiological correlations in regards to temperature and measure of heart beats. This technical observance of meditative practice is also a medical methodology toward that idea of meditation. It's called Quieting.
It is a layman's observance of these measures which are used to help the person gauge progress through those quieting times. This record keeping helps to build confidence. Also from my perspective this is where cursor control becomes understood, not just with neurological path tracking.
