Mind-Machine Interface Could Lead to New Life-Changing Technologies for Millions of People
“Brain cap” technology being developed at the University of Maryland allows users to turn their thoughts into motion. Associate Professor of Kinesiology José ‘Pepe’ L. Contreras-Vidal and his team have created a non-invasive, sensor-lined cap with neural interface software that soon could be used to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars.
“We are on track to develop, test and make available to the public- within the next few years — a safe, reliable, noninvasive brain computer interface that can bring life-changing technology to millions of people whose ability to move has been diminished due to paralysis, stroke or other injury or illness,” said Contreras-Vidal of the university’s School of Public Health.
The potential and rapid progression of the UMD brain cap technology can be seen in a host of recent developments, including a just published study in the Journal of Neurophysiology, new grants from the National Science Foundation (NSF) and National Institutes of Health, and a growing list of partners that includes the University of Maryland School of Medicine, the Veterans Affairs Maryland Health Care System, the Johns Hopkins University Applied Physics Laboratory, Rice University and Walter Reed Army Medical Center’s Integrated Department of Orthopaedics & Rehabilitation.
“We are doing something that few previously thought was possible,” said Contreras-Vidal, who is also an affiliate professor in Maryland’s Fischell Department of Bioengineering and the university’s Neuroscience and Cognitive Science Program. “We use EEG [electroencephalography] to non-invasively read brain waves and translate them into movement commands for computers and other devices.
