Well this is very interesting. This computer system can determine when a persons brain activity is being overloaded and in return adjust the computer interface to take that load off of the user. While I am not sure this works (need to see this research peer reviewed and read it), I am very intrigued by the possibilities and promise this holds in both the cognitive load and human computer interaction research.
“Their system, called Brainput, is designed to recognize when a person’s workload is excessive and then automatically modify a computer interface to make it easier. The researchers used a lightweight, portable brain monitoring technology, called functional near-infrared spectroscopy (fNIRS), that determines when a person is multitasking. Analysis of the brain scan data was then fed into a system that adjusted the user’s workload at those times. A computing system with Brainput could, in other words, learn to give you a break.”
