How to catch the signal of the brain? Or how to make a brain controller?

Question

IT education

Tell me or tell me how they make various kinds of brain controllers
Today I came across such a thing

I was very interested

Answer 1

no way, the brain is too complex a system for some kind of magnet on the forehead to actually take data from it. you can indirectly register the activity of a certain zone, which says absolutely nothing, except that there is activity) besides, the brain is very individual for everyone.
in general, my opinion is not to engage in scientific shamanism, for quality control we have hands and joysticks)))

Answer 2

https://ru.m.wikipedia.org/wiki/Electroencephalography
It is necessary to measure the potentials of several points on the head relative to the ear (for example). These signals will indirectly indicate the activity or inactivity of the brain. Here's what to do with these signals. Some kind of classifier is needed.

This article and video is very close to your idea:

Answer 4

The thing is interesting. Do you want to make it yourself? I think it is possible, but for this you need to understand electronics and spend a lot of time assembling radio components, programming. It's easier to buy.

Answer 5

This crap most likely only reacts to the excitation of certain parts of the brain, which are usually quite quiet, well, for example, that it flew, a person should just imagine how it takes off (it doesn’t really matter, he should imagine anything at all), get excited accordingly the part of the brain that is responsible for .. hmm, which is responsible for the ability to imagine (I think Google will easily find the answer for you), then they should make a reader for the direction of their gaze, put 3 sensors, one fixed anywhere, the second on the head (with the ability to determine not only position, but also rotation) and one per catfish flying thing. And a lot of coding to make it possible to process the entire data stream quickly enough. Example, after excitation of this part of the brain, the engine is started, the position of all three sensors and the distance from them are determined. the distance is fixed, then the reading direction of the gaze begins, respectively, this device goes to that point, the path is defined as a sphere around by a sensor installed on a person, and on the phone you can change the size of this sphere. Further, in order to cut off the control, for example, you need to close one eye for a second, then the device just has to hang in place, to turn it on again, close the eye for a second.
Well, in general, it will turn out to be a funny thing, the control can of course be greatly improved and probably simplified

Answer 6

The thing on the head seems to be something from neurosky. As far as I remember, neurosky has such a device with bluetooth - and the output format is described there.
