Re: Emotiv EPOC driver status

Hi Robert,

currently we officially only support the VS2010 tool chain, as we do not have a VS2012 installation available yet. After the next release we will be doing modifications to the build system and may support VS 2012 as well. For now I would recommend you to use VS 2010.

Regards
Jozef

Re: How do communicate OpenViBE with other App

Hello gibfen, OpenViBE can indeed communicate with external applications, as long as they support VRPN connection. You can look at this tutorial: http://openvibe.inria.fr/vrpn-tutorial-sending-data-from-openvibe-to-an-external-application/ other methods can be implemented as well by using the script...

Re: Emotiv EEG compatibility

Hello, the OpenViBE Emotiv EPOC driver is intended for this headset. Currently there is a Windows version available and it is pre-installed with the software. You will need to have the research version of the headset for the driver to work, as this is the one which gives you access to raw EEG data. ...

Re: 2D topographic map - 4 Views

Hello Pedro,

unfortunately there is no way of defining the projection before running the scenario for the 2D topographic map at the moment. It is certainly a nice feature to have and would be a great contribution to the software.

Cheers

Re: Calculating Alpha, Beta, Delta, Theta w. Emotiv

Hello roschler, there is actually no need to create any additional code. OpenViBE already has all of the necessary components to do the calculations by itself. You should use the temporal filter, as suggested. The only necessary change is to set the filter to act as a band-pass filter for the spectr...

Re: how to Correct??

Hello uahmed, sorry for the late reply, most of us were currently on holidays. There is actually no error in this output. The WARNING messages you are getting are from the Stimulation Listener box which is set to the Warning log level for its output and are not actual warnings. You can change this l...

Re: About saving feature vectors to CSV file

Hello Yichuan, CVS File Writer indeed writes data as it arrives into a 2D matrix, however the second dimension consists of channels! If you want to cut the data by epochs, I would suggest calculating the number of vectors in 1 epoch and then slicing the file accordingly in another program. Cheers Jo...

Re: Adding a lib

Hello, OpenViBE is built using CMake build system so I would suggest you get familiar with it (the best would be to look at the CMakeLists.txt files included in the folders of various openvibe projects. There is already a script for including matlab library created in the catalog of dependencies. In...

Re: open vibe on android

Hello, currently OpenViBE is written and supported on x86 and amd64 Linux and Windows builds. There is no version of OpenViBE for ARM architecture and Android OS. Moreover, we depend on proprietary libraries for most of the drivers, in particular the Emotiv EPOC headset. Whereas there should be no p...

Re: VRPN settings in external VR application

Hello Ashish, could you send me your test scenarios so I can look at them? This problem is indeed weird and I do not know how it could work with the keyboard stimulator if the output is exactly the same (also note that the keyboard stimulator sends a stimulation on both keypress and keyrelease) Chee...

Re: Connecting Emotiv to openViBE on Ubuntu 12.04

Hello Synonyms, for now the Emotiv EPOC OpenViBE driver only works on Windows as we do not have a copy the Linux SDK available yet. If the connection to the SDK is similar to the Windows version then it should not be very difficult to modify the existing driver to be compatible with the Linux SDK, b...
