"For those who just can't call it quits, a team of researchers at Tufts University has developed a head adornment which can determine when you've been overly stressed, bored or simply numb to the world around you when using your computer. The crew is studying functional near-infrared spectroscopy (fNIRS) technology, which \"uses light to monitor brain blood flow as a proxy for workload stress a user may experience when performing an increasingly difficult task.\" The band itself utilizes \"laser diodes to send near-infrared light through the forehead at a relatively shallow depth,\" after which it can purportedly judge how intense one's workload is (or isn't). 'Course, we'd guess the most of us wouldn't need a machine to tell us that, eh?[Via InformationWeek]"^^<http://www.w3.org/2001/XMLSchema#string>
