When I first heard about this I was really impressed....then as I read more (from different sites) about it I became kind of disappointed......And now
I've come around to being impressed again.....Just not so much as I originally was.
Let me explain why. At first I thought this was an actual representation of someone's thoughts....as in they were seeing something on a screen a
computer was decoding the 'analog' brain signal and digitizing it and then reconstructing it....a true brain reading device. That is not precisely
what is going on.
Instead a person is watching clips...and a computer is monitoring their brain....Then the computer goes through a whole bunch of random movie clips
from Youtube and makes a guess.....It's still impressive...but it's not decoding what your brain is visualizing......It's making a guess based on what
your brain is doing. To make it more simple...Imagine you are watching the face of someone watching a movie. You see fear on their face. Now imagine
that you have ten random movie clips.....Two of them are from horror movies....You would likely guess from watching the expression on the person's
face that they were watching one of the Horror movies. That is what is going on here, except instead of watching facial expressions.....the computer
is watching the subtle signals of a person's brain.....then picking from a very long list of possible choices, and making a guess. Still impressive
but just not quite as impressive as directly decoding the visualization inside the brain.
What bothered me about this, was the method used in producing the image ....making it appear more psychedelic....as if it was the actual rough analog
signal from the brain....Like a static TV signal, with ghost images from random stray thoughts. This is not what is going on.....it is only a blending
of the 1st and 2nd and 3rd ( and so on) best possible choices. To me it had seemed like they had intentionally led people astray with this
method....Making them think the computer was doing something that it wasn't.
I've since eased up on my criticism a bit....After learning that none of the possible images had come from a list of clips that the subjects actually
saw.....It may make a bit more sense that they had to blend them together to make a good guess. Though I still feel that it was presented in a
slightly misleading way. Just my opinion.
