Hi Yann,



I'm trying to compare the Beta wave state against the Alpha/Theta wave state, and then implementing the presence of Beta waves to my VR game.

Is it possible that I can view the rest of the algorithm of the above example scenario (taken from OpenViBE homepage->Medias->Other Applications->Neurofeedback) for reference?

I was testing out my VR game, but I wasn't too sure whether I had gotten the correct data that I wanted, so perhaps understanding the level measure toolbox would help me greatly in data accuracy and reliability.

Hope you can advise

Best regards,
Will

Dear will9twl,

the scenario you are talking about compares relative beta levels at C3 and C4. I attached a similar scenario.

There are two things to consider for what you are trying to do :
- There is no way you can compare two different frequency bands in the official release for now. Some partners are currently working on that. However, I guess you could quickly create a new box to compute such ratios.
- The level measure is currently pre-processing the input matrix before actually displaying it. The pre processing consists in computing the relative contribution of each value to the sum of all values at a given time. I agree this should not be

I don't have time to fix that for now, but I'll help as much as you'll need.

Best regards,
Yann
