Robert Oschler sent in this cool video which allows you to control a Rovio Robot using Mind Control. It uses the Emotiv system to allow the monitoring of your mind and other facial gestures. It isn’t a cheap technology yet but I think as this type of application catches on the pricing will fall.
“The Emotiv SDK is a full-featured, professionally executed toolkit for quickly integrating the EPOC headset’s rich detection suite into your applications. As with any SDK, you do have to be a programmer (or at least know one) to make full use of it. But I believe even an advanced beginner would be able to do a lot. As for non-programmers, quite a few people have added support to other applications for the EPOC headset using the time-honored technique of keyboard stuffing.“
