Signal quality in recorded file

[electronic monk]

btw,i wanted 2 ask u also another thing...
can it b that muse2 will record different data than muse1?
or that the gyroscope interferes with the data?coz with muse2 i get different graphs when sitting vs lying down!

also,wanted 2 ask u about the y axis u have changed and said that it doesnt really mean anything,was -1 to 1,could b a-z,just showing the relatuion between brainwaves...y dont u put the dB on the left side?wouldnt that b more logical since the recording is also in dB so u can compare but also c the actual dB?

yeah,but the problem is that u start ok,horseshoe disappears but then it loses connection while u r meditating,or gets weaker then stronger but u cant c that coz u have ur eyes closed... so when i c a graph which looks strange i check the CSV and c the bad connections...
so when its bad in ur online graphing it will show as BF and when it goes below 4 as GF?

I think they're both the same. The sensor strips are the same on all three versions of the Muse.

To do a comparison you'd need to record both Muse's on the same brain data at the same time. You can't do that on a real brain, but you could hook up both devices to a test signal generator and see what happens. The Gyro and Accelerometer are passive measuring devices, so they won't change anything.

I have all three Muse versions and my tests on my own brain show they all work the same.

I don't show units on the y axis units on the chart because Power Spectral Density doesn't have any official units.

You don't need to close your eyes when you're meditating. Interaxon automatically filter out blink data. Just don't flick your eyes around looking at stuff as that will generated a lot of interference. If you're just looking at Muse Monitor, that'll be fine. Muse Monitor wouldn't be much fun if you couldn't look at it

ooohh,and now that i started,let me ask u also something else

have u thought about including a warning sound in ur app for bad connections as they have in the muse app?
that would b great coz many times i play around til the horseshoe disappears but when i close my eyes i cant check anymore,so it happens many times that i stop the recording,happy and excited 2 c the graph,and find out that after a few minutes the fiffin thing lost connection and i c a straight line!!!!

can u integrate that in ur app somehow so we know when the connection is bad so we can open our eyes and fix it?
also ,good connection = horseshoe disappears , medium connection circles r not filled with color,and bad connection = straight line? is that correct?

i dont need 2 close my eyes when meditating? did i read that right or was it a typo?
there may b meditation techniques with open eyes but the majority is with closed eyes,so most people will have their eyes closed while meditating,including me....

If you're loosing connection that often then you're not wearing the Muse right, or you're wiggling your eyebrows

If you want it on all the time, you can toggle "Hide horseshoe" in Settings.

As for how it works, I will refer you to the Help:https://musemonitor.com/Technical_Manua ... _horseshoe

Let me clarify; you don't need to close you're eyes when using Muse Monitor.

How you meditate is up to you.

It will help signal quality to not blink, but blinks are filtered out by Interaxon's algorithms, so if you do blink, that's fine. Obviously if you deliberately blink continuously then your results will be junk, but a "normal" amount of blinking is fine.

well,i didnt have any problem with connections all those months,but now it started and its a hardware issue many people experience with muse2,they r aware of it and trying 2 fix it,so when this happens and u did everything right,they will replace the headband,and it happened many times with many people since the launch in october...

yes,of course i know that u can use muse monitor with open eyes,but most if not all people meditate with closed eyes,and people in the muse community have been talking about this issue and wishing 2 have a warning sound 2 tell them that the connection is bad or even lost so they can open their eyes and fix it...

so it would b great if u could include that in ur app

[James]

Wouldn't that be counter productive to have a buzzer going off when you're trying to meditate?

[electronic monk]

yes,but its better than having a wrong graph lol

and it doesnt have 2 b something super loud or as the muse app does where it stops the session,just a beep would b enough,like this little sound from a watch it does every hr...and u can include also an option 2 turn it off if u want,or if u r meditating already 2 long then not 2 react coz u dont wanna break the session....
