Thanks! What do you mean specifically by the bandwidth? Regarding hallucinations, not musical, but visual hallucinations occur. Checkout the paper "Gravity Jockey" about that.
I'm utterly fascinated by this technology and was curious if there could be a means of transmitting notation or rhythm from the brain to a computer or even speaker. This technology is certainly a precursor to that and wondered what your thoughts were. Keep up the good work!
@@caydengineer I've read a couple studies which may suggest it's possible to interpret notes that someone is thinking and translate it to midi data by measuring certain brain waves but to my knowledge it hasn't been fully transmittable with standard EEG. Seems farfetched but the technology is getting closer.
I agree. There's interesting work that's been done in VR with GVS (galvanic vestibular stimulation) from the MIT Media Lab and others. Also, it can be used to decrease motion sickness. Very cool!
How does vestibular stimulation enhance the enjoyment of music? And are the "motion cues" somehow derived from the recording, or are they added separately?
More work needs to be done in terms of a psychological study to verify that GVS synced with music is improving enjoyment of music. Current supporting evidence is anecdotal from ~15 people who have tried it and enjoy it. The GVS signal is directly computed from the music audio signal in a signal professing pipeline. You can check out some of how we do that via the git repo in the video description.
@@caydengineer Thanks. Do you have any subjective descriptions of what it feels like? Also, in the video you integrated the device into a pair of headphones, but I assume it could be worn separately and used with loudspeakers, correct?
@@bathynomusgiganteus2916 It feels similar to when you turn sharp in a fast moving car, rock in a boat, or tip in a chair. Yes, many of the tests were performed with just a headband and using an external speaker. We built a custom syncing system so that the bluetooth delay did not cause the brain stimulation to be out of sync with the music. Thanks for checking it out!
I do understand it's a whole new thing and can be scary to think what effects might there be to one's brain. However, tDCS has been shown to be incredibly safe over many years and 10s of thousands of participants: www.ncbi.nlm.nih.gov/pmc/articles/PMC5007190/
How long until I can buy one?
I'm not sure about that Rod. Things move quickly and we'll have to see what happens!
Super impressed with how far you guys took this with the custom boards and everything! Awesome tech always, keep up the videos!!
Sick. Nice work guys! What’s the bandwidth on the TACS? Did you experience music “hallucinations” via stimulation? Or just the vestibular effects?
Thanks!

Would you be able to elaborate? "Notation or rhythm from the brain to a computer", what do you mean?

I feel like this tech would pair well with a VR headset

Too worried about potential side effects to ever try something like this tbh.
