I recently came across this TED Talk:
OMG, we're on our way to a frakking Holoband! OK, so we're a ways away still from the Holoband, but controlling a computer through thought is an important step towards virtual world-creating technology like the Holoband, the "headspa" or whatever it was in Minority Report, and similar sci-fi gismos (I'm not so sure about the holodeck, since I think the person actually walks around in a holodeck, but you get the idea). This Emotiv EPOC seems like something out of science fiction, but here it is right now.
Some of you may remember how excited I got about the Kinect. This seems considerably harder to use (so much concentration), and it doesn't have as many current applications as the gaming system will have once it comes out, but IT READS YOUR BRAINWAVES! It's one thing to wave your arm and have an image on screen move in front of you. That's pretty cool, but it's pretend telekinesis, since it's your arm movement and not your mind directly controlling it. But to be able to make it move with just a thought? Real telekinesis. In a virtual world, sure--unless you then have another application on the computer that will move an actual physical object. And there's something appealing and satisfying about having to concentrate and train yourself to control the program. Using the Force takes focus and practice, after all.
I definitely see there being applications for handicapped people, particularly as the technology is further improved. But I am awfully tempted to buy one just because. Just because my old-fashioned brain is having trouble believing it exists. And just because I've always wanted telekinesis.
