Our correspondent Shaun Saunders was perusing the LiveScience.com page and came across this little gem. As odd and funny as it sounds, these people are dead serious!
They're already predicting, mathematically, what you'll want to watch, what you'll want to wear, and who you'll want to vote for. Obviously, the next step is for computers to read your mind. Your computer won't be picking up details about your plans for the evening anytime soon. But researchers with the Human Computer Interaction group at Tufts have, thanks to a $450,000 grant from the National Science Foundation, come up with a straightforward way for your computer to tell if you are overworked, under-worked or not working at all. The mind reading actually involves measuring the volume and oxygen level of the blood around the subject's brain, using technology called functional near-infrared spectroscopy (fNIRS). The user wears a sort of futuristic headband that sends light in that spectrum into the tissues of the head where it is absorbed by active, blood-filled tissues. The headband then measures how much light was not absorbed, letting the computer gauge the metabolic demands that the brain is making.
