Brain-Computer Interface

In this post, I’ll comment a few researches that I have made on BCI (Brain-Computer Interface) devices.

Connecting to the brain directly makes me remind of old days, when I first saw Matrix and Neo being literally plugged using a giant jack. Is that real? The plug is not of course. But indeed, EEG fans can use a few commands by simply thinking of it. It even seems easier to track facial signs like smile, blink, etc.

So why bother to talk about gloves and headsets? Well, capturing brainwaves isn’t that sharp, because they get messed up by the skull, so from the outside electrodes get a lot of noise. They barely catch that an area of the brain is being active (as blood circulates more intensively). And this is a one-way capture, although a few mad scientists have tried to “write” brainwaves!

Of course, intrusive BCI devices like the BrainGate (that we will soon post on) can achieve a far better understanding of mind thoughts, but I assume very few people will get a chip in their motor cortex…

Besides, EEG capturing devices require quite some time to learn and train, because thinking of a move without doing it is actually strange.

Fortunately, EEG capturing devices improve and no longer require slimy and sticky electrodes.

All in all, pros and cons for BCI devices, but eventually, they can be correlated with other devices to replace other commands. Let’s say I’m wearing glasses with HUD and I want to capture a video of the amazing woman crossing my way: I would just need to concentrate on her. Which – I guess – shouldn’t require too much effort and learning :-p
