Is the accelerometer supported of the Muse 2?

Hi James:

You write here:

https://musemonitor.com/FAQ.php#Compatibility

that "Interaxon have not yet released a Software Developer Kit (SDK) update to support the new PPG sensor in the 2018 "Muse 2" Model MU-03.
All other data is available."

So the accelerometer of the Muse 2 is supported by Muse 2, is this correct?

You write also, that:

"In their forum post (Where I am Enigma644), Interaxon have not given any indication of when they will update the SDK and I encourage everyone who would like PPG data to post a message on there. As soon as Interaxon update the SDK, I will add PPG data to Muse Monitor".

But I found here:

https://choosemuse.com/development/

that "Muse temporarily stopped actively supporting the Muse software development kit (SDK)"

Do you know anything about this?

Yes. Accelerometer is supported on the Muse 2. The only data unavailable is the PPG.

Regarding the SDK, yes I've seen the message. I'm still holding out hope they will bring back the SDK soon, but in my spare time I'm working on my own SDK.

Great that the accelerometer of Muse 2 is supported by the Muse Monitor, James!

Arnaud Delorme, the developer of EEGLAB has published a series of youtube videos how to process Muse data with EEGLAB:

https://www.youtube.com/watch?v=omn7y3TIsGc

Arnaud Delorme explains in these videos how to manually erase artefacts in muse data which are caused for instance by movements.

With the aid of accelerometer data, these movement artefacts could be removed automatically. Garmin has a similar solution for his stress monitor. The stress monitor is only working when the watch is not moving.

I m looking for a way to get these Muse accelerometer data into Matlab, as live as possible, for further processing.

Arnaud Delorme published also an example how to connect to LSL streams on Matlab:

https://github.com/sccn/labstreaminglay ... h-the-Muse

Unfortunately, it requires the Muse SDK, but I can t find any downloadlink for it. Do you see another way how to stream the Muse data incluse accelormeter data live to Matlab?

It's possible with Muse Monitor's build in OSC streaming. I recall some people talking about it on the Interaxon forums a few years ago.
My MatLAB trail has expired, so I'm unable to test it myself, but it's definitely possible.

Here I found something:

https://ch.mathworks.com/matlabcentral/ ... lab-64-bit

I m longing for the good old days when there was an easy way to solve this problem by downloading the Muse software development kit (SDK) :twisted:

Here I found another helpful link for MUSE and Matlab:

http://forum.choosemuse.com/t/muse-and-matlab/44

Unfortunately, I cannot pair my Muse 2 over bluetooth to my PC. I tried 2 different PCs according to this instruction:

https://www.google.de/search?as_q=Pair+ ... TM44TwDQ17

I can see my Muse headband 2 with the serial number in the bluetooth search engine window on PC. But when try to pair, I always get the same message on both PCs: paring unsuccessful, try again to pair.

what could be wrong :evil: ?

The Muse 2 is almost impossible to pair on PC. I've tried many different Bluetooth USB devices and none of them work. It was similar with the 2016 Muse. Only the 2014 Muse is easy to pair on PC. This is why I only made Muse Monitor for Android/iOS.

Thank you, Muse expert, for your answer.

It s a shame, that Interaxon does not support the LSL interface developed by the Swartz Center for Computational Neuroscience used by Arnaud Delorme, meditation researcher and EEGLab developer, one of the best horses in the stable of the Muse headband:

https://github.com/sccn/labstreaminglay ... h-the-Muse

https://github.com/sccn/labstreaminglayer/issues/30

Unfortunately, the Swartz Center for Computational Neuroscience has also chosen also an easy way to pair the Muse headband to the PC, which does not work with all Muses :( .

So I choose Muse Monitor to pair to my PC. Can I pair Muse Monitor with bluetooth to my PC? Or do I need a Wifi network for it?

Muse Monitor has an OSC streaming option to send data over WiFi to a Mac/PC.
Or you can just record direct on your device with Muse Monitor and then look at the recordings in the online chart viewer at https://MuseMonitor.com/Chart.php

R_Cassani, wrote code in matlab to acquire the muse-io OSC output (EEG and acceleration) in matlab online (1Jul '14)

http://forum.choosemuse.com/t/muse-and-matlab/44/4

but unfortunately, the code is not available anymore. :shock:
