Newbie in OpenVibe

Post by deepindraw »

Hello everyone,
I am relatively new to OpenVibe and I am doing a project on developing a GUI for BCI system.I need to develop an EEG recording tool for mental workload/effort using NeuroSky Mindwave & Emotiv Epoc based in OpenVibe platform. These will be the main tasks in step by step order:
1) The software should be able to visualize the incoming time-based raw data and previous calculated mental states from the EEG.
2) Calculate the frequency bands from the raw data
3) Store data sessions in an exportable format
4) Build a classifier that recognizes the mental workload of the user

Since I don't have regular access to the Headsets, I have recorded some sessions with it and working with the recorded data. Until now, I know the basic things such as performing a session, recording them in files and loading them for next session. Now I want to proceed with the step 1. So, what do you I should have knowledge about or what tutorials should I read/watch to be able to visualize the incoming time-based raw data(in my case the pre-recorded data since I don't have regular access to the headsets). And how can I calculate the mental states(attention and meditation) from the previously recorded data?

Looking forward to your suggestions,tips and help. Thank you very much in advance!

Hi,

Check box tutorials in the folder share/openvibe/scenarios/box-tutorials and you will find all examples you need to answer to all your point.
Some of them are listed in this page http://openvibe.inria.fr/box-tutorials/ (the page is not up to date, some tutorials has been add).

Hi Guillaume, thanks for the links.
I'm able to visualize the incoming time based raw data. Any idea how can I visualize the previous calculated mental state from the EEG?

Thanks for the response!

Greetings,
Deepen
