Brain-Computer Interface
OCZ - a modder company selling overclocking and cooling devices normally - has introduced a computer brain input interface. No its not an "coming soon product" it is apparently available to buy pretty much now for a mere US $147,00. The devices detects brainwaves, facial muscle movements and eye muscle movements to enhance your input possibilities. There is a great writeup from hothardware using it and reading that makes me very itchy. This could very well be a great additional solution to some input woes with complex programs - especially complex programs that need fast reaction time or programs were you need to push more buttons at once then you have fingers. Like VJ programs for example... Sadly the device is Windows only at the moment and mostly aimed towards gamers. But I expect this to become a common form of input if it is really working as described in the article.
