Subtitles section Play video Print subtitles A few years ago I came across these commercially available E.E.G. headsets, NeuroSky, these As part of my company that I was running at the time We started experimenting with different games and different things to do with them but the main thing that we started doing is like taking edits, taking video edits and then dropping them into a program that would allow the view to cut basically. We're using like just stuff off the cutting room floor really. This was a different way of making a film as I usually do usually like you script it, and you storyboard it and go out and shoot it. This one was made specifically with the interactivity of the film in mind. We had to do like four different treatments from the script and then also in editing I usually you I take the viewer on and journey in the edit and you choose very succinctly, when, what they see when they see it And this, the creativity that you would put in the edit that gets passed off onto the viewer Interviewer: How does it work from a technical point of view? This sits on your head electrical signals from your brain and also from your skin it gets filtered out and sent via Bluetooth We've got a Python program here. Interviewer: So that's live Data now Yeah, it's just getting like fuzz at the minute (Quietly to self) Just stick this on. So, as a I put it on The signal quality should drop to zero and that means I've got a good connection with the data coming out so you can see in the background the film's playing as I blink it's cutting As you can see as I blend between two layers that's my attention going from high to low You see if I blink, you'll see this blink coming up. When I press play it fires off four videos at once, they're all playing in sync. And when I blink it chooses a set of two videos to play. When it's playing those two videos, the attention is changing the blending between those two videos. When I blink it will jump to the other two videos. Blending between those. At the same time meditation is controlling the mix of the music so the higher my meditation level the more levels of the music. So the data is coming from the headset via Bluetooth to the computer then our Python program is picking that data up send it via OSC (Open Sound Control) to MaxMSP, which is a program a lot of artists use code. It's a visual programming language It looks a lot like this So the data comes in here from the headset It's receiving the blink, the attention, the meditation It's coming down there to blink to cut between scenes. and then over here the the meditation has been scaled to the four audio levels, so we can see So my meditations about 50% here. That one's going up a bit. You just like add these patch cords together so there's there's my meditation point for it's between zero and one so I've got that number This bot- This number here, so you can see it's 35 which is round about here? And it's going up, 66. Interviewer: Do you find some people are more in control of their brains than others? Yeah totally and like I've had a few people who do a lot of meditation in the morning they are really able to control the meditation aspect of it, most people can't control that at all The biggest differences of people, [is] how people want to control the film some people want to experience a film some people want to control it and a few Group experiences where there was like one person who just wanted to see their feedback And they made this crazy film that just really hurt other people's heads so this was initially designed as a one-person experience initially we had a lot a little tent and you went in and just watched it by yourself when we took on tour we found that people would have a little bit....
