Tufts University researchers have begun a three-year research project which, if successful, will allow computers to respond to the brain activity of the computer's user. Users wear futuristic-looking headbands to shine light on their foreheads, then perform a series of increasingly difficult tasks while the device reads what parts of the brain are absorbing the light.
That info is then transferred to the computer, and from there the computer can adjust it's interface and functions to each individual. One professor used the following example of a real world use: "If it knew which air traffic controllers were overloaded, the next incoming plane could be assigned to another controller." Researchers will present early results this week at a R.I. symposium.
