Thought-powered helicopter takes off

Help

Researchers have harnessed the power of thought to guide a remote-control helicopter through an obstacle course.

The demonstration joins a growing number of attempts to translate the electrical patterns of thoughts into motions in the virtual and real world.

Applications range from assisting those with neurodegenerative disorders to novel modes of video game play.

The research in the Journal of Neural Engineering uses a non-invasive "cap" to capture brain electrical activity.

Prof Bin He, director of the University of Minnesota's Institute for Engineering in Medicine and senior author on the new research, explained how it worked.
