to be completely pedantic, i already control all games i play with my mind... more seriously, i worked on a brain-computer interface (BCI) system a few years ago that was supposed to do directional control of a cursor from scalp EEG recordings. A $90 eye tracker worked an order of magnitude better and three orders faster.

For VR, you could even just use the headset's forward-vector, making it like Cardboard's 'look to select' interface.

Earlier quoted context omitted.

I realize you were joking but "get of my lawn" is normally something that the rich say to the poor. In this situation it's the opposite. Also, I'm young enough to be in the "next generation" and, at least in my case, the GP is wrong. The previous generation assumes they can get lost in the noise. They imagine all our data flowing into a human machine for processing. They don't understand the power of machine learning…

>I realize you were joking but "get of my lawn" is normally something that the rich say to the poor. No it's not. A lawn is a very middle-class thing in the US. It is stereotypically an older person that spends a bunch of time keeping their lawn pristine since they have no small children. https://en.wikipedia.org/wiki/You_kids_get_off_my_lawn !

Exactly. The rich have signs that say "Get off my lawn"... The middle class have to get off the couch to say it.

Late states of some progressive diseases eventually affect eye movement too (ALS, for example) - so there are some use cases where EEG recordings could be important.

I've spent a lot of time working with EEG and pulling my hair out over garbage SNR, finnicky setups, and artifacts galore. I don't understand why so many folks try to go the route of using EEG as mouse/keyboard/generic HID for the masses, when (ignoring para/quadraplegics) most humans have no problem with computer input. There are tons of applications where the EEG can be used for what it's (sorta) good at: attention…

Yes the primary commercial application found in the EEG literature seems to be fatigue monitoring for professional drivers. Certainly "control" BCI applications won't be the first Neurotech killer app.

What I really want is a highly sensitive position tracking set of breathable gloves, probably with some mild electric feedback. We have have loads of sensitivity and control in our hands. Why bother to dangerously wire to the brain when you can input/output via the hands? There would be a learning curve, but if it's possible to read braille and use sign language, I'd think it's possible to relay information to the hand via electric stimulus and from the hand by tracking movement.

Wiring stuff directly to the brain has the nice side effect of improving the tools we use to understand how the brain works. It also helps us develop better prostheses (for example for people who lost their hands).

If you want to experiment with an EEG device, that works look at Muse. They emphasize meditation feedback, but you can access your EEG raw data. http://www.choosemuse.com/research/

I've been wanting to get one to try some ideas out, but trying to decide if the $200 is worth it. Do you have a muse? What do you use it for?

Do you know of any viable setups for using eye tracking in daily computer use? I think it would be pretty nifty to be able to control my mouse while having both hands on my keyboard.
