CNN report on the future of brain controlled devices.
In part :
“Brain-computer interfaces (BCI) come in two varieties. Noninvasive techniques use electrodes placed on the scalp to measure electrical activity. Invasive procedures implant electrodes directly into the brain. In both cases, the devices interact with a computer to produce a wide variety of applications, ranging from medical breakthroughs and military-tech advances to futuristic video games and toys.
Much of the research focuses on neuroprosthetics, which offer a way for the brain to compensate for injuries and illness. “
