Brain-computer interface with EEG: how to name imaginary movement of a non-self object?
As far as I know, brain-computer interfaces based on EEG use motor-cortex responses by asking the subject to imagine body movements. E.g., a left-arm movement imagination would translate to moving the robot to the left etc. In other words, imagining the robot going left will probably result in a diffuse, poor-defined brain response, while imagined motor movements are more useful.
