I'd love to see the uncertain looks on a loved one's face as they pulled this out of the gift wrapping. That there is Emotiv's $299 Epoc Headset and, if the hype is to be believed, this or similar technologies will one day replace computer mice, joysticks et. al.

The Emotiv EPOC is a high resolution, neuro-signal acquisition and processing wireless neuroheadset. It uses a set of sensors to tune into electric signals produced by the brain to detect player thoughts, feelings and expressions and connects wirelessly to most PCs.

For over a millennium, mankind has dreamed of the ability to control objects with the power of thought. Today that dream has become reality! Now you can experience the fantasy of having supernatural powers and controlling the world with your mind. The Emotiv EPOC is designed for the PC and is bundled with a demo game, some demo apps and emokey [utility software that maps thoughts to keystrokes]. You can extend download/purchase additional applications from our online application store.

Question: Will it work through bedhead, bad hair days and/or hats?
