Japanese student demonstrates walking in a virtual world
Japanese student demonstrates walking in a virtual world, on a flat screen monitor, with the character controled by his brain waves, in Yokohama, in 2007. A Japanese research team has advanced even further by creating a technology that could eventually display on a computer screen what people have on their minds, such as dreams.

I think we're all getting ahead of ourselves here.

One would assume there would be a huge leap from crude images to full-color, high-def dream movies. I don't think we have to worry about our inner-most secrets being revealed any time soon.

I remember 20 years ago, when virtual-reality was supposed to be right around the corner. It's just now approaching what the experts were touting back then.

True VR isn't that far away. You need 1) a way to detect what the brain is trying to do (already exists), 2) a way to impose signals on specific neurons (already exists), and a way to stimulate the part of the brain that cuts off voluntary movement during REM (that unfortunately is a deep structure, so we're not there yet). There's no real basic science left to develop -- it's jus engineering. Since the technology would be very valuable to the two main drivers of information technology -- gaming and porn -- I expect it to be perfected by a week next monday. :-)

@D666
not only that, however. The most complex part of VR is not capturing or sending signals, it's finding out what the signals mean and being able to mimic them. So VR is still far off, unless someone starts linking specific pathways in the brain to specific senses (an image of a bird, most likely, should have a completely different signal form that of a plane). It's these little nuance that really make all the difference. And with current research into the field, I'd be surprised if we have 8-bit games in our heads in a decade.

Actually I would imagine that this may help psychologists or psychiatrists to treat people with sleep disorders or other sicknesses, if they learn how to interpret effectively the dreams using this technology.

Also, it would be interesting to see how that would help the doctors to interpret the mind of a autistic person.

The exciting part here is capturing and decoding signals to the brain. There are so many questions - does everyone send the same signals for the same visual input (or within a % of variation), or is everyone unique in their signaling? Is there a pattern/order in which information is sent (distance, size, texture, color, etc.)? Does signaling relate to how the particular brain is constructed? How to distinguish between the various signals received - this part of the signal means this, while that part means that? When we only think of items, are they signaled the same as when we see them?

Lots of questions still, but this sounds very exciting.

I'm sorry if I disappoint but if I understand this article correctly we won't actually be able to see what anybody is dreaming. You see, what they are doing is capturing messages from the retina and decoding their neural positioning to construct the image directly from the brain. The problem is that when dreaming, we don't receive any retinal information.

However, if they succeed in tracking the higher functioning concepts of WHAT (objects) we're seeing then we will be able to tell what someone is dreaming about. Unless the visuals of a dream are constructed in exactly the same way visual information is read from sight, then "seeing" a dream would be as difficult as telling somebody a word and "seeing" what it is they picture in they're mind.

Actually seeing an approximation of what they see could be very difficult as it'd probably involve many parts of the brain, especially the parts involving visual and spatial reasoning.

Not quite. They do capture retinal signals, but merely to find out which parts of the brain, and what signals, signify what image. That is, the retinal part of the study is only to determine a pathway. They then use the knowledge of these pathways to try and decode thoughts in the person, and supposedly they managed to get the same letters out and spell the same word.

In a large sense, you are right, but what they are trying to do is find the higher functioning concepts of what the objects they are seeing are. The retina is merely to control what they are decoding (i.e. they know that the signal means "n" or "neuron" or whatever, versus blindly guessing at what it may mean.

Interesting work! If this technology advances, I would imagine that the first group of people to take advantage of this technology is not the porn or gaming industry but the intelligence (i.e. CIA). How? Accessing people's memory of course. We can trigger and record a person's memory by "flashing" the brain with a few familiar images which activates the neural pathways/patterns associate with the images, or in another term "remember". A suspect does not have to be interrogate or question. Just hook him/her up to the machine, show a few pictures of places and/or people and record whatever the suspect "remember" of the places/people and the conversation that took place. This technology can also help people with dementia. Sounds like sci-fi? Well, not for long.

have you ever thought about living your dreams
it might not be as strange as it seems
traveling into a world you call your own
all by yourself yet never alone
killed ten times and you never die
when your in dreamland you wonder why
a collection of thoughts thru the night
are mass confusion in morning light
if you ever wake up without your head
roll back over because you are dead

I have a question, Would the signal my brain has for the letter "n" be the same as everyone else's ???? Doesn't seem like there would be that kind of uniformity among people.

Nice :) But they didn't mention how individual these signals are. Because if the word "neuron" has only 6 letters and 5 different ones, the brain can think for so many more different things. If you have to see like 5000 pictures in order for this device to work, that's little unpractical. Though, you can have it with you during your day and to have anything you see recorded on a camera. This could be a nice calibration. That device is so exciting!
