Scenario Validation
Posted: Sun Feb 18, 2024 4:53 pm
Hello!
I am a PhD student working in OpenVibe for the first time and I have no signal analysis experience. I am calling upon the OpenVibe community for comments, suggestions and validation on my scenario.
Here's one of the sub-objectives of my research: I need to know the attention employees pay to learning activities in an elearning course.

Here's one of the sub-objectives of my research: I need to know the attention employees pay to learning activities in an elearning course.
- Input: I have recorded EEG data for 20 subjects using a Unicorn 8 channel 250 Hz headset while the participants were doing a 25-30 min elearning course. The data for each participant is in a CSV file.
- Treatment: I need to isolate Beta, Alpha and Theta bands for Cz, Pz, P3 and P4 in order to calculate Pope's index of attention using a Hanning sliding window
- Output: a csv file with that index, to which I'll be able to add event id for specific time periods
- Is the attached OpenVibe scenario valid for what I am trying to do? If not, please let me know how to fix it.
- Should I be applying Signal decimation and if so, where?
- My output CSV file returns error messages (sampling rate cannot be 0, error have been thrown during streamed matrix, plus others). What am I doing wrong?
