NeuroSky has made a system which can turn brainwaves into commands. This is a revolutionary technique that will have a big impact on all kinds of markets.

But also the elderly can benefit from techniques like this: not physically having to move to control electronic devices/machines around the house. Watch the videos. Must see.
