It would be a better control mechanism. NeuroSky (the headset used here) is only good as an eye blink detector and even at that it’s not great. EEG reading on the forehead, without gel is always really bad because there are no obviously interpretable signals (frontal cortex is way more complex than, say motor regions or the occipital nerve), the skin is tougher due to no hair, and is way too much muscle interference.
Something with two electrodes behind ears (or wherever the muscles responsible for moving ears are) could be even used as a tool to train to move your (human) ears.
- musingsole 5y agoThe Muse 2 headset has ear and forehead sensors. I'm not too up on EEG, but I'd believed the ear sensors were just for grounding/baselining what's read from the forehead. Blink detection at least is pretty robust when I've played with it. https://choosemuse.com/muse-2/ https://choosemuse.com/muse-2/
- yoz-y 5y agoyeah, ear sensors are for a ground and a reference, to be able to remove noise from the EEG (basically you are trying to have a channel which has no EEG) Muse is more or less couple of neurosky's glued together. With multiple sensors you can at least get to know which eye blinked, extract stuff like raised eyebrows and such. But dry electrodes on the forehead will never really give any good EEG results. There was a paper when somebody managed to get P300 working with neurosky, but they needed to average something like a 1000 trials. This is tens of minutes of looking at a flashing screen.
