Neurologists at the Wadsworth Center in Albany have designed a cap that allows people to manipulate a cursor on a screen by just thinking. Previously, this has been achieved only by invasive methods where small wire arrays were placed within the brain to monitor individual brain regions.
The focus of the research is on helping the disabled be able to control computers and by extensions, lights, robotic arms, etc. Personally, I can’t wait until they just release the cap for general use. Not having to push a mouse around would be a big relief to my wrist, but I wouldn’t want to have brain surgury just to be free from the threat of carpal tunnel syndrome.
