Repost from CogSci (posted in wrong forum).
You may be aware that neuro-signal-capturers (I'll leave out specific ones to make it not seem like an ad) have become much cheaper and many are available with a SDK. I think this will open up a huge gateway for much more intimate human interfaces. However, I am stumped at the practical uses and whether the human controlled interfaces will be much better to the user. A mind controlled TV remote (for hospital patients) came as an idea, but once again, I don't think it has much practical use. Could any point me to any practical uses of this device? I am sorry if I am posting in the wrong section or this is a very opened-ended question. Thanks for any input.
EDIT: I am talking about devices like OCZ Nia.
EDIT2: More specific question. Are there any applications for such a device where there isn't already a device that accomplishes such a task with much less effort and lower learning curve? In my case, the hospital TV remove (disregarding the possibility where the patient might be completely immobilized), the already existing remove suits the task very well since it is intuitive, very easy to use and has a low learning curve.
