I came across an article in a Sunday newspaper a couple of weeks ago about an artist called xxxy who has created an installation using a BCI of sorts. I’m piecing this together from what I read in the paper and what I could see on his site, but the general idea is this: person wears a portable EEG rig (I don’t recognise the model) and is placed in a harness with wires reaching up and up and up into the ceiling. The person closes their eyes and relaxes – presumably as they enter a state of alpha augmentation, they begin to levitate courtesy of the wires. The more that they relax or the longer they sustain that state, the higher they go. It’s hard to tell from the video, but the person seems to be suspended around 25-30 feet in the air.
The installation by xxxy is called The Ascent – you can read more about it here and watch a couple of short videos.
I don’t think they use the EEG signal to bring the person back down to the ground again – you would have to be very confident of your ability to control alpha waves to do that from 30 ft up in the air. I like to think of it as the ultimate relax to win dynamic, either relax or plummet to the ground from a great height. But seriously, it did make me think about the approach in a therapeutic context; for those who suffer from a fear of heights, this kind of controlled exposure to a vertical ascent plus alpha augmentation might have some benefits.
As I say, the details are kind of sketchy so apologies in advance if I got anything wrong.
