OpenViBE forum

Hello everyone!

I would like to create a simple SSVEP Speller based on the OpenVibe SSVEP scenario. In the past I often used Processing as developing environment, because you quickly get some useful results, and I would like to use it again.

Unfortunately I haven't been able to find a VRPN library for Processing so far. Does anyone have an idea, how to include VRPN into Processing?

I'd welcome any help.

Hi Peegee10,

We have actually done something similar with colleagues. We have connected OpenViBE and Processing via VRPN using Java (not for SSVEP but for motor imagery or P300 though, but the approach is exactly the same). To do so you have to use Java, since there is a VRPN library for java (which comes with the C++ VRPN library in the official package). We used Eclipse to do so which was rather convenient. In Eclipse you add the Processing packages so that you can call processing functions from your Java code, which Java code will be implementing the VRPN client. I have attached two java files doing that (one is the VRPN client, the other one uses this VRPN client and calls Processing functions) to give you an example. The main drawback of this solution is that you have to be able to code in Java. However, I don't know any solution to directly use VRPN in Processing.

I hope this helps,

Best regards,
Fabien
