Hi, I am stuck with this issue for a while now. In the handball scenario, the classification state from the classifier processor is sent to the analog VRPN server and to the VR application. I am trying to do a similar scenario to turn an object left or right , but not using analog VRPN server. Inste...

Hi Jozef, Thank you for replying back. This problem is really killing me :( . But, here's what I have done so far as you asked: Yes, I am using the exact same implementation as in the tutorial for VRPN except that I have compiled the code in an external MS Visual Studio project and exported the nece...

Hi Jozef,
I also found out that the log is spitting out this message in intervals:

<Player::can not reach realtime> 58 second(s) late...

I am not sure if it has to do with the VR application not getting LEFT/RIGHT stimulations in real time.

Thanks,
Ashish

Hi Jozef,
Actually I figured out the log manager part. I seem to be getting the correct OGTK_GDF_Left and OVTK_GDF_Right stimulations.
I guess then something must be wrong with my VR code which I have posted in the previous reply. May be you can see what I can't!

Thanks much,
Ashish

Hello Jozef, Thank you for the information. I have a stimulation listener box that listens to stimulations from the classifier processor. I could not precisely find where the logs are printed. Is it in the dist/log/openvibe-designer.txt? Or how do I use the log manager ? I could not find any documen...

Hello All, I am facing a problem with my openViBE /VR application setup. I created a simple VR application in Ogre3d which makes an object move to the left or to the right depending on the class left or class right classification from an OpenViBE scenario. My scenario is very similar to the Motor Im...

Hi Fabien, Thanks for the insight again. Much appreciated! I indeed got the classifier accuracy box to work. As for Emotiv Epoc and motor imagery, I am using the F3 and F4 channels which lie slightly above the C3 and C4 in the 10-20 system. I have to slide the headset back a little to place those el...

Hi Fabien, Thank you for your quick response! That made some things clear to me . I do have a few more questions, if you don't mind. These are related to the Motor-Imagery-CSP filter scenario with Emotiv Epoc Headset. So, I have to use a feature extractor and a classifier for any BCI scenario to get...

Hello everyone, I am using the designer for a Motor Imagery scenario similar to the one that uses a CSP filter. I have a few questions bugging me. So, my training with the Graz visualization results in a CSP filter config file (cspconfig.cfg) in about 2 minutes 01 secs. And, the classifier trainer p...

Hi, I am trying to build a new VR application to work with OpenVibe using VRPN and Ogre3D. I have the source files application folder in /openvibe-applications/vr-demo/trunc/src/myappfolder. I am basically following the example as explained in http://openvibe.inria.fr/documentation/unstable/Doc_VRAp...
