Coonecting electrodes on the head
Hello, I read documentation on where to put electrodes on the head if we want to have electrical signals (catch by the ModularEEG). If we put one electrode on the Cz area, one on the forehead (ground electrode) and one on the nose (reference electrode), we can detect foot mouvement. But where exactl...

Re: Openvibe and a virtual keyboard
Hi, I resolved my problem, I used the stimulation train trigger OVTK_GDF_end_of_file in the classifier trainer and I used the box Acquistion to get the signal. So the trigger was never activated. I used a gdf reader file and it worked. Can you please give us examples of simple cerebral commands in o...

Re: Openvibe and a virtual keyboard
Hello,
Thank you for your help.
I have this error on the console : "no response from the server"
I think that the error is in: ana = new vrpn_Analog_Remote("openvibe-vrpn@localhost");
I don't think that I should put: ("openvibe-vrpn@localhost"), do I ?
