Researchers Aim To "Read Minds" of PC Users 121

hhavensteincw writes "Scientists at Tufts University are researching the use of light aimed at the forehead to measure the stress, work overload, or distraction a computer user may be feeling, as a way to adjust the UI to adapt to a user's emotional state. The research combines biomedical engineering and machine learning to adjust the UI. The project, which requires users to wear a futuristic head band, uses light to measure the flow of oxygenated blood to the brain that signals a user's rising stress levels typically associated with increasingly difficult tasks."
