Neurotechnology Could Lead to Thought-Controlled Devices

To interact with a computer, users generally type on a keyboard, swipe their fingers across a screen or speak a voice command. What if, instead, the machine simply responded to their thoughts? Researchers at the University of California, San Diego have spent years developing a portable cerebral monitoring device that when wrapped around the head — similar to a virtual reality headset — can allow users to control a computer by simply thinking what they want the machine to do. Specialized software enables this headset to interpret brain activity, translating it into commands. “These are the early days for neurotechnology, and there is yet much to discover,” says Tim Mullen, a Ph.D. graduate of the university who is developing the software. “The rate of scientific and technological progress in the…
