Scientists have designed a novel, noninvasive system that allows users to control a virtual helicopter using only their minds, as reported in the online journal PLoS ONE.
The researchers, led by Dr. Bin He of University of Minnesota, created an EEG-based, noninvasive brain-computer interface that allowed users to accurately and continually navigate a virtual helicopter simply by thinking about where they wanted to craft to go.
The task required users to direct their helicopter through randomly positioned rings in three-dimensional space; these targets were reached successfully 85% of the time.
Much of the previous work in this field required invasive treatments that allowed for measurement of intracranial activity, but this new approach employs EEG in the form of a cap on the user's head.
This noninvasive technique records a particular brain wave called the sensorimotor rhythm, which in turn can be characterized and calibrated to control the movements of the on-screen helicopter.
According to lead research Dr. He, "this work demonstrates for the first time that one can accomplish real-time, continuous 3-dimensional control of a flying object in a virtual world from noninvasive EEG-based brain-computer interface.
Such ability used to be limited in cases where invasive recordings are used, thus the work opens avenues to noninvasive bio-navigation, or neuroprosthetics."

Video game makers ready barrage of blockbusters
San Francisco (AFP) Oct 27, 2011
Video game makers are breaking out the big guns and hitting players with a barrage of dynamite titles that will compete for their devotion and entertainment dollars this holiday season. Bethesda Softwork's freshly released "Rage" blends brilliant graphics with fast-paced combat on foot and in vehicles in an expansive vision of an Earth rendered wasteland by an asteroid strike. "Resistanc ... read more
