I've benn working with a group of people developing brain computer interfaces (BCI) using the Emotiv Epoc neuroheadset. Until now we developed two different BCIs, one speller based on the P300 signal, and one based on SSVEP (steady state visually evoked potentials). These two BCIs work fine, they are kind of accurate. Now we want to design a BCI that doesn't need external stimuli, based on motor imaginery. We began recently with this project, but in this case we are not getting the results we expected (although we still have a few things to improve). It's known that the Emotiv neuroheadset doesn't provide a clean signal (low signal to noise ratio, etc), and I wanted to know what other people in this subject think. Do you believe that because of the limited precision of the hardware (Emotiv neuroheadset) we are facing a dead-end? With high density EEGs people have developed accurate BCIs based on motor imaginery, do you believe that the precision of the hardware is a limiting factor, and not matter how much we develop the classification algorithm we won't be able to make it work?
