Problem about self-disconnection of the Acquisition Server
Hi all, I explain my situation. I'm using the SSVEP online test scenario, and I send the results of the classification to a c++ code, and then the c++ program send that data to Simulink via udp protocol. It happens that when all these things run together (OpenViBE, Visual Studio with c++, Simulink),...

Re: A simple question about stimulus & signals in OpenViBE
For the community: finally i found a very nice solution. To translate stimulus in signals you can use the Stream Switch box: you have in input your stimulus and whatever signal/streamed matrix, and then you can filter your outputs with DSP (simply transforming outputs in different constants). Hope t...

A simple question about stimulus & signals in OpenViBE
I am involved in a simple issue: I would like to translate the stimulus output of the Classifier Processor Block in a signal. Any rapid solution to do it? I seemed it simple in theory, but practically I don't know how I could implement it. Es.: OVTK_StimulationId_Label_01 >>translate in>> constant s...

Re: SVM classifier: inputs, outputs and parameters
Fabien thank you so much for you very clear reply.
Soon I will try that implementation and I'll post the results.
Thanks,

Re: VRPN : Sending data from OpenViBE to an external ap
Finally I find the solution! For the community, regards to what I wrote in the previous posts: - Simply I add the file vrpn.lib (that is in pc_win32>Debug in the directory downlaoded from here: http://www.cs.unc.edu/Research/vrpn/obtaining_vrpn.html) in [right click on Visual Studio Project]>propert...

Re: VRPN : Sending data from OpenViBE to an external ap
Thank you so much for your reply. You can get a compiled vrpn that openvibe uses by running win32-install_dependencies.exe from scripts/ in the openvibe source archive. vrpn will be found afterwards under dependencies/. Are you able to give me some clearer guidance about how to do that (that is not ...

Re: VRPN : Sending data from OpenViBE to an external ap
I have understood that the problem is in these two strings of the c++ code fo the tutorial:
VRPNButton = new vrpn_Button_Remote( "openvibe_vrpn_button@localhost" );
VRPNAnalog = new vrpn_Analog_Remote( "openvibe_vrpn_analog@localhost" );
Why?
VRPNButton = new vrpn_Button_Remote( "openvibe_vrpn_button@localhost" );
VRPNAnalog = new vrpn_Analog_Remote( "openvibe_vrpn_analog@localhost" );
Why?

SVM classifier: inputs, outputs and parameters
Hi, here http://openvibe.inria.fr/forum/viewtopic.php?f=17&t=9239&view=next I told that I am using the SSVEP scenario with the SVM classifier instead of the LDA. I have two questions: 1. How in OpenViBE I can normalize the inputs of the SVM classifier? Someone suggested me to use the univariate stat...

Re: SSVEP: problem with the SVM classifier
Hi, I am sorry, in reality I am confused. The output of the classifier processor used as a SVM classifier, is a stimulus that rappresent the label of the classification result. It is not a signal between 0 and 1; Am I wrong? And Fabien, could you are more specific with the example of an implemeted n...

SSVEP: problem with the SVM classifier
Hello, I am using the ssvep scenario (with Emotiv Epoc device), and I wanted to change the LDA classifier with a SVM classifier. I have some doubts/problems: 1. I read that with SVM classifier I have to shift the inputs of the Classifier trainer block by -0.5. I have not very clear this point, it is...
