Love the thread! Been building a bio and neuro feedback controlled "Temple Run" like game that runs entirely in the browser (Web Bluetooth to hook into a Muse EEG and a heart rate monitor, 4 channels running FFTs, WebGL, etc). I really wanted a fun way to get me to use EEG training for focus and managing anxiety/stress. So... here we are. Pretty close to Show HN ready. Thinking I might post one if anyone thinks it sounds interesting.

Would be awesome! For fun, I built something similar where you could control fire in an open world. Basically learning to control powers. Would love a show HN! We also tried a Kickstarter for some more personal help stuff. https://www.kickstarter.com/projects/synaptitude/thinksuite-brainware-not-software/rewards https://www.kickstarter.com/projects/synaptitude/thinksuite-... Question — how (if anything) do you correct for head movement? That’s the big challenge I’ve seen with accuracy, we had some algorithm developed on it (happy to share, if interested).

  Thanks for the feedback! I’ll email you directly because the head movement thing sounds really interesting. Short answer to your question… I don’t/I cheated. I was inspired by my friend who launch the successful Kickstarter “throw trucks with your mind”. His feedback for corm/focus algorithms and training was to group and average a few seconds of data. So I run my FFT‘s every (doing this from memory, might be slightly off) 50 ms looking back about a half a second. Then run it through the calm, focus, and anxiety algorithms I wrote. Lastly I average over 5 seconds to reduce wild fluctuations/“death spirals” (users freak out mentally when they see calm: 80 -> 0 -> 50 -> 2) and spit that out to be user facing. So it sort of smooths over blinks/head movement/etc. At least, I think so. Will DM and thanks for the feedback! (And I’d love to see the control fire thing - I did something similar where you can levitate, high jump, slow fall, etc. I just suck at/have never really done game design so it stalled out.)
