How to move online model into "production"

My goal (for now) is to use my EEG to turn a LED on and off. I have trained a model in OpenViBE and tested an online version of the classifier model. So far, so good. Now, if possible, I would like to avoid relying on the GUI interface. I would like to load my online model as minimalistic app on the...

Re: Using Graz Motor Imagery BCI Simulator with single class

Hi Hackr, you can look into the ERP Recording Tutorial to see how Cue Display is used to show different images depending on the events in an experiment timeline. The Cue Display box doesn't show feedback (unlike Graz Display box) but its easier to use it to show a lot of different images (arrows, c...

You can use box:log(log_level, line_of_text).
Sample script from OpenViBE also suggest that io.write should work.

Cheers,
That's very helpful, thank you very much!

Re: Using Graz Motor Imagery BCI Simulator with single class

Can anyone recommend an example using Lua Window or display cue, etc? I have the exact same objective as this OP did 5 years ago.

Incidentally, what does the word "Graz" mean? I'm just curious. None of the definitions I found online made sense in this context.

Is there a way to print from a Lua script to the console?

I was experimenting with editing a Lua script in the motor imagery example scenario. For learning and development purposes, I was wondering if there's a want to print data in the Lua script and have it appear in the OpenViBE console? If not, is there some other way to print values in the Lua script?...

Understanding coefficients of the Spatial Filter boxes

Hi, I am new to OpenViBE and am trying to understand classification. I'm currently working with the example scenario classification-0-training.xml . My understanding thusfar is the noise generator was used to simulate data you'd receive from an EEG device via the Acquisition server/client (or a reco...

Re: New tutorial: Recording Event Related Potentials (ERPs)

@jtlindgren Thank you for this great tutorial! It's the most useful I've found thusfar. 2 questions: 1. Was there an example Lua script to go along with it? 2. I want to do what you did in the tutorial, but proceed to training, then classification, then execute commands/scripts based on those classi...

Missing boxes that are in examples

Hi, I'm trying to follow an ERP example that I don't really understand, and to make things a little bit harder it seems that I'm missing several of the boxes. Here's what I'm trying to replicate: http://openvibe.inria.fr/openvibe/wp-content/uploads/2017/01/openvibe-erp-recording.jpg Here's the boxes...
