OpenViBE forum

Hi jayseye, I have moved this conversation to the subforum about building OpenViBE. Considering other than supported architectures: Most of the time the compatibility of OpenViBE depends solely on the compatibility of its dependencies. Sometimes minor tweaks to the code are necessary with different ...

Hello Ashish, are you using some framework to use the VRPN events? In the implementation described in the OpenViBE to external application tutorial here: http://openvibe.inria.fr/vrpn-tutorial-sending-data-from-openvibe-to-an-external-application/ I use callbacks rather than looping on the VRPN hand...

Hello The supported versions of Linux are always: - the last two Fedora distributions at the time of the last release - the last LTS version of Ubuntu at the time of the last release (currently Ubuntu 12.04) - the last non-lts version of Ubuntu at the time of the last release (currently Ubuntu 11.10...

Hello Ashish, Your second implementation is correct (using the same stimulation for ON and OFF signals). This is because in this case the VRPN button acts as a toggle button, that is, it changes state everytime the given stimulation is received. For your problem with receiving right/left/right/left ...

Hello amufti, I can see that the Emotiv Control Panel is not running. This is necessary because OpenViBE connects to the headset by their proprietary software. In order to help you further with your problem we will need some details about your installation. Which version of Windows 7 are you using? ...

Hi,

all of the function definitions are in the OpenViBE Matlab toolbox which can be found in OPENVIBE/dist/share/openvibe-plugins/matlab

Hello Shelldream, which procedure did you use to install the sources of OpenViBE? Did you download the source package as an archive or used the SVN? Note that the trunc folder you are referring does not exist inside the share/ folder. It is found it the ROOT_FOLDER/openvibe-applications/acquisition-...

Hello Yichuan, ChunkStartTime is created by the acquisition server upon receiving data, in the designer this time is always relative to the starting of the scenario, as all the data received by the acquisition server while there is no connection is discarded. ChunkEndTime is calculated from the Star...

Hello Enrico welcome to the forums. There is indeed a box in OpenViBE used to present the images, called Display Cue Image . This box displays an image upon receiving a stimulation, you can define multiple images and map them to different input stimulations (by adding additional settings to the box ...

Hello Louis, glad that you have found a temporary solution to your problem. Indeed there were several reports about the MindWave mobile not working with the current version of the driver. As we do not have the device at this moment there is not much we can do immediately. We will keep you posted on ...

Hello Andrea, a new release of OpenViBE is approaching (it will be probably released around december) and we would like to integrate your contribution into the software if possible. As we do not have the device of our own (and the g.Tec API), we would like to know if you have finalized the driver (a...

Hello Shelldream,

the matlab filter box needs to know the location of your Matlab installation, this has to be done by the user. Have you indicated the paths to your matlab installation in the box configuration?

Hello atom2004, there are several ways to communicate stimulations to external programs. You can use the VRPN button box to send them via the VRPN protocol, if your target application supports that. Otherwise you can create a socket connection using either the Lua Stimulation Box or Python Scripting...

Hello, plenty of example scenarios are bundled with the OpenViBE software already. You can find explanations of most boxes in the dist/share/openvibe-scenarios/box-tutorials folder. More complex scenarios explaining the use of BCI paradigms and demo applications are in dist/share/openvibe-scenarios/...

Hello Jose, I do not know about a method to convert VRPN to keyboard stimulations, however I am aware that VRPN interface with blender engine was already implemented. ( here is a demo : http://www.youtube.com/watch?v=qr6XfbeYDFA ). I do not know whether the developers of this software are still acti...
