The problem is translating neural signals to images. Our firing patterns are unique. We have over 80billion neurons and over 500trillion synapses. Decoding brain signals into high resolution graphics would be hard.

The work around would be training. If we are shown known videos and images it is more likely a system could learn a brain’s signals. However, I don’t think it would be possible to use a helmet off the shelf and get it to work.

I agree completely. A simple EEG machine and headset costs 6 figures or more. A consumer headset and console would have to be miniaturized and made much smarter.

I went off hospital equipment prices. I wasn't aware of this. Thank you for the reference.

By comparison, these look like you could put together a "research grade" EEG setup for under $5k.

For the sort of data needed to extract imagery, it would have to be a high resolution signal. I don't know if it is even possible yet. Some mentioned taking word fragments and producing generated imagery, but that's very different from "recording" imagery from someone's brain.
