How accurate is OpenBCI for sleep tracking?

Max Eastwood from Thailand published in the www.openbci.com forum some results where he used:

  • OpenBCI Cyton with 8 channels
  • and OpenBCI Daisy with 16 channels

for sleep tracking. And he showed some graph of sleep staging:

And also some graphs for relative band power:

The Dreem 2 headband with 4 EEG channels has about 80 percent of the accuracy of a professional polysomnography device. These are rather low accuracy values:

Gold standard for Polysomnography requires a 12 channel device, which is rather complicated:

  • It would be interesting to know how accurate an OpenBCI 16 EEG headset is for sleep tracking.

Since is an EEG cap with for instance 16 EEG channels not much more comfortable to wear than the device shown above?

  • Frederik D. Weber from Donders Institute for Brain, Cognition and Behaviour, Radboud University Medical Center, The Netherlands has written an instruction for a sleep lab with OpenBCI with 8 or 16 channels.:
OpenBCI
  • Frederik D. Weber describes his instruction a “sleep lab for less than $1000 with OpenBCI”
  • SpiSOP (abrev. for Spindles Slow Oscillation and Power-spectral-density) is an open source tool supporting detection and reporting of spindle or slow oscillation events, their co-occurance or respective matching non-events and power (density) of specific spectra or frequency bands in pre-scored (sleep stages) EEG and MEG data as well as simple automatic EMG artifact detection.
  • So it is something really serious.
  • It is a software which runs in Matlab.
  • There is also Python software available such as the Python Sleep Software.
  • And it would be interesting to know how accurate OpenBCI with 8 and 16 channels is for sleep tracking.
  • We think it should easily beat the Dreem 2 headband as far as accuracy is concerned, since it has much more channels.
  • Dreem 2 is not availably anymore for anyone, but OpenBCI.

Information for product sellers who do stock market speculation and scalping with products mentioned by Peter Gamma on www.petergamma.org

According to the little experience of Peter Gamma from www.petergamma.org, many of the products listed here are still full of issues which need to be resolved. If you do stock market speculation and scalping with those, you will loose Peter Gamma from www.petergamma.org as a buyer of these products and as a reviewer. Is this not risky? Will you not loose a majority of your costumers as well?

And is it not so, that society in general does not accept stock market speculation and scalping with products as those which are listed here? And will you not be politically incapable of finding a majority of the voters if you do stock market speculation and scalping with these products?

And as a consequence will you not be condemned and punished by a political referendum soon? Especially if you do this to a Swiss, since are not majority of Swiss against stock market speculations and scalping with people on a budget? And people in Switzerland are known for a lot of political referendums, since we have direct democracy in this country.

And Peter Gamma from www.petergamma.org will fight up to the European Court of Human Rights against people who do stock market speculation and scalping with the products which are mentioned on www.petergamma.org. And if they do not have yet the legal basis there to do so, he will fight for it.
