Wearable Brain Scanner Tells Your Computer When You're Overwhelmed

Researchers at MIT are developing a wearable, portable brain monitor that tells a computer when its user is mentally overwhelmed. Using a brain imaging tool called functional near-infrared spectroscopy, or fNIRS, the system detects when a person is multitasking and tells the computer to adjust its interface to make things easier. The technology could take a load off the minds of air traffic controllers and other workers who must constantly perform at a high level, regardless of changes in cognitive state. Functional NIRS detects brain activity by using light to scan for changes in blood hemoglobin concentrations. The technology can sense not only that someone may be multitasking, but can also distinguish between different kinds of multitasking. Erin Treacy Solovey, a computer science postdoc at MIT, and her colleagues have been testing the tool using virtual robots designe...
