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.

Good points.

You say an order of magnitude, do you have any information about generational increases? Like was last generation an order of magnitude worse than what you worked on?

our control paradigm was steady state visually evoked responses -- these are low-frequency components of a scalp EEG rig that correspond to the visual cortex locking on to a blinking test pattern. On a good day with a bald subject and fresh gel, decoding time is between 6 and 11 seconds.

A tobii eye tracker has a latency of about 30 ms.

Spatial discrimination is oodles better, too.

next generation will love this, while us old fart will scream about the ethical issues of recording and uploading brain scans to the private advertisement companies that'll run billboard in the virtual worlds...

Get off my mind lawn!

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 and fail to grasp the degree to which this data will increasingly determine outcomes in their individual lives.

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: attentional and mood states, which, in the time of distraction firehose, seems like it would have a use case. But no, we have to make yet another pick-up-a-virtual-object interface.

(not to imply X-aplegics are not worthy of tech. it's just that as mentioned above, eye tracking is WAY more robust)
