Headset that reads your brainwaves

Since I am trying to make a connection to my Knowledge Management course and everyday life, I decided to take a look at the category of technology under the TED Talks. I stumbled across a topic of "A Headset that reads your brainwaves"; The topic seemed interesting because not only at this point is my brain fried from all the information I have received in the last 24hours I only wondered how much a wireless headset could do. Tan Le who is the engineer of this piece of genius, explains how this piece of equipment can read your brain waves and ultimately you can control anything with this headset from turning off your lights to controlling a automatic wheelchair hands free by just smiling or winking your eyes. Wow you may say, I had the exact sentiment. Not only now is the Internet overloading our brains but now there's a headset invading our brains. What's next for technology? You have to see this:
