Fast Fourier Transform Box

Hi,

I'm wondering if anyone is working on a box which would enable Fast Fourier Transform, which I think would be better for extracting frequency components from the EEG measured for Neurofeedback application.

Thanks!

Regards,
Will

Re: Sample scenarios

Hi Yann, http://openvibe.inria.fr/openvibe-snapshot-app-02.png I'm trying to compare the Beta wave state against the Alpha/Theta wave state, and then implementing the presence of Beta waves to my VR game. Is it possible that I can view the rest of the algorithm of the above example scenario (taken f...

Re: Sample scenarios

Hi Yann,

Thanks for the advice. I've been able to continue working on the integration of OpenViBE and my Ogre3D game.

Also, I saw the posting the robotic arm video on the homepage. Hopefully, after I stabilize my tests, I can contribute on the section as well.

Best wishes,
Will

Re: Sample scenarios

Hi Yann, I've been trying to write a very simple program (view code below) just to test out the VRPN connection, but it doesn't seem to be working with the 2 errors I've included below. I've questioned myself over the header files, but I've included all the header files downloaded from VRPN into my ...

Re: CSV export

I found the option to use semicolon as separator.

It is under Data tab, and under Text to Column icon of MS Excel 2007.

Re: CSV export

Hi I guess what you mean is an issue related to opening a CSV file with an external software like Excel or Access? If such is the case I would suggest the following. Instead of opening the CSV file directly by double clicking on the file icon, first open the software (like Excel or Calc). Then, fro...

CSV export

Hi,

I'm trying to use the CSV writer, but the files that I write, I want the values to be in separate columns and not separated by the 'semi-colon'. I've tried /t but it doesn't seem to work. Hope someone can advise on creating tabs.

Thanks a lot!

Re: Sample scenarios

On the VRPN side, the class you should look at is vrpn_Analog_Remote . This class is very easy to use... You basically have to create an instance of it, connect it to the VRPN peripheral which should be observed (e.g. openvibe-vrpn@localhost ), register a callback for data arrival notification and ...

Re: Sample scenarios

Hello, here is a sample tie-fighter like scenario. In the archive, you will find a GDF file that you should put in your openvibe-scenarios/signals folder. The XML scenario file can be put wherever you want. This scenario was used in order to lift the tie fighter in our VR-demos. It is based on beta...

Re: Sample scenarios

Hi Yann, So I'll have to write a game program on Orge3D, and then configure it to 'seek and receive' VRPN inputs from OpenViBE? Furthermore, does that mean I have to download and install VRPN separately or would OpenViBE take care of transmitting VRPN inputs to Orge3D automatically through the desig...

Re: Sample scenarios

Hi,

Does anyone have any suggestions on any available Virtual Reality software that I can utilize in use with OpenViBE?

Or simply put, what are the recommended Virtual Reality software to use with OpenViBE for neurofeedback purposes?

Best regards,

Re: Add the g.tec driver

Hi Yann,

I turned off the firewall and I could connect the g.tec gUSBamp to the application client on the same PC. Thanks for the advice.

P.S. I'm not too sure where to locate the custom configuration file. Could you elaborate further?

Best regards,
William
