IBM says mind control next big thing in human-computer interaction; GLaDOS offers cake reward
From the ongoing Google-Apple turf war on voice recognition to Microsoft's gesture tracking with Kinect, humans continue to push the envelope on how to interact with computers and devices. Now IBM says mind control will be the next field to see a big leap, predicting breakthroughs within the next five years. Keep in mind that they're not talking about controlling humans a la Gorilla Grodd ... yet. Instead, they're talking about controlling computer actions and devices via brain waves. IBM software guru and potential Borg recruit Kevin Brown (pictured right) has already been using a headset to move cubes on a computer screen at will. Given the ongoing progress with mind-controlled cars and BrainGate, IBM's prediction might not be too far-fetched.
BrainGate hits 1,000 day mind-control milestone, nearly three years of pointing and clicking
Aspiring Svengalis rejoice! For BrainGate has reached a significant landmark in computational thought-control -- the 4 x 4-mm implantable chip has given a woman with tetraplegia the ability to point and click with her brain for 1,000 days. An article recently published in the Journal of Neural Engineering said the woman, known simply as S3, performed two easy tasks every 24 hours, using her mind to manipulate a cursor with 90 percent accuracy. Each day she was monitored, S3 would post up in front of a computer and continuously command the thing with her thoughts for 10 minutes. Functionality reportedly deteriorated over time, but the paper points to the chip's durability, not sensor-brain incompatibility, as the culprit. Research is currently underway to incorporate BrainGate into advanced prosthetics that could get tetraplegics like S3 up and moving again. Now, how's that for the power of positive thinking?
Mind-controlled wheelchair prototype is truly, insanely awesome
We've seen brain-controlled wheelchairs in the past, but we've never seen them in action. This one, developed and built at the University of Zaragoza in Spain, uses an EEG cap worn on the head, using a P300 neurophysiological protocol and automated navigation. The user sees a real-time visualization of his surroundings on the screen in front of him, and then concentrates on the space which he wants to navigate to. The EEG detects the location, which is then transmitted to the autonomous navigation system, which then drives the chair to the desired location, avoiding any obstacles that might be in the way. Once the location has been chosen, the user can sit back and relax while the chair does all the work, making the use of the system far less mentally exhausting than some previous iterations which demand constant concentration on the target. Although there is no information about commercial availability of the wheelchair, it has been successfully tested by five different participants in a study. There's a video with a more detailed explanation of its impressive operation after the break.
