is it possible to stream PPG data? I tried looking at the wrong output from dispatcher and looking at the settings, but I didn’t see a way to do this. i’d ideally like to be able to stream data related to heart rate.
Thanks for all the help, and being so responsive to my questions!
Streaming PPG data
Re: Streaming PPG data
Yes. Just enable the extras by tapping on "Mind Monitor" in settings 10 times, and then reconnect the Muse.
Re: Streaming PPG data
Hi, I am developing an app using using the Muse SDK. I have the raw PPG data packet... how do you translate those raw data into heart rate? thanks! Billy.
Re: Streaming PPG data
Tap on "Mind Monitor" in settings 10 times, and then reconnect the Muse. You will get a prompt that it's enabled after tapping 10 times.

Hi All,
First of all, thanks for the app, very helpful for our research.
Second, I just wanted to mention that if I tap 10 times on MindMonitor, I don't get this notification about being enabled/disabled. It just jumps out of the settings, showing the graphs again. However, if I close the app, turn off the Muse2, then start the app again and turn on the Muse again, then I can see the pulse.
So if others struggle, maybe just play around and see whether you get the data.
This is Mind Monitor 2.3.1[44] with a Muse-E947[MU03] on Android 10 (and Android 5!
)
Best wishes,
Andre

Re: Streaming PPG data
Correct, you need to disconnect and reconnect the Muse after toggling the setting.
Re: Streaming PPG data
Is there a reason to not make it just a regular setting with a switch?
Re: Streaming PPG data
The PPG algorythm isn't good because the raw data can jump like crazy if you move your head and get light leak. Move your head around on the Gyro/Accelerometer and look at the raw data. You'll see how bad it is to process!
Re: Streaming PPG data
Thanks a lot for the explanation, I'm all new to this.
So for heart-rate variability (HRV) analysis which of the columns in the output file would you recommend to use?
PPG_Ambient PPG_IR PPG_Red Heart_Rate
I plan to look into Kubios (free) to analyse the data, but haven't started yet.
BTW, I'm interested in using HRV as a rough measure of physiological arousal/stress, and we are interested in longer periods (say at least 5 min, up to 15/20 min). I hope that for such analyses the data can be filtered to remove outliers, bad data, etc and there remains sufficient data for just an average HRV score for these periods. We don't plan event-related type analyses.
