I have written in the past about how we will be able to control machines using our thoughts alone. Advances in research into our ability to do so seem to be coming more frequently. The latest is news from MedGadget, out of the University of Minnesota. A team there has been able to employ non-invasive electroencephalography (EEG) to enable people to grasp and move objects.
The fact that they were able to accomplish this non-invasively is significant. Brain-machine interfaces have generally required the implanting of electrodes in the brain. Obviously, being able to move to a non-invasive model will open up technology development possibilities and should speed up advancement in the field.
The MedGadget article sites the benefits to disabled persons in being able to manipulate machines with their thoughts. I can foresee the technology also being useful for scenarios such as remotely manipulating robots placed in hazardous environments.
