Video: Mind-reading tech reconstructs moving images others see

Let me get this right... the patient was actually seeing a parrot, but the fMRI brain scan shows up a witch instead.

... the patient was actually seeing a Steve Martin, but the fMRI brain scan shows up a demon instead.
... the patient was actually reading "all bets are off" image, but the fMRI brain scan shows up a "No No" hellfire that transforms into some poorly formed Chinese characters instead.
... the patient was actually seeing an Afro- boy with a stethoscope, but the fMRI brain scan shows up a red-faced hippie blob instead.
... the patient was actually seeing a ROL BROWNER, but the fMRI brain scan shows up a PORTILLO middle easterner instead.

People in comas communicate just fine. They just don't want to talk to you, Laura Shin.

What an absurd comment, Qasimara. At the long-gone days of the early XXth century, you'd have to keep still along hours just to get photographed. Now everyone has a cellphone with a 4-5 megapixel camera.
Imagine into what could this develop.

This technology cannot see what the user sees! What it seems to be doing is analyze how a brain react at seeing certain patterns or colors. Then when seeing another picture it creates a composite picture out of known pictures that match the reaction. Of course it can't recreate the images, but the fact that its recognition is fine enough to do what is shown in the video is astounding! Considering this tech is just being developed it has me hyped on the potential uses down the road!

. . . plants are not very healthy, are they?

I should have been shown a quadtych. The image being watched, the fMRI image created from watching that and the image(s) borrowed to make the composite and the fMRI images from watching them.

Just wait until it gets perfected and the U.S. government gets their hands on it, I'm sure they'll use it to further deteriorate our privacy rights, or lack thereof....
