OpenViBE MATLAB Filter to Arduino

We want to send the classification output computed from EEG signals in the bci_Process function of the MATLAB filter to an Arduino board. We are unable to receive the output (a single value +1/-1) on the Arduino COM port on which we created the connection. Here is the code we are using: function [ma...

Send data to Android Application

Is there a way to send data from OpenVibe to an Android app over a wireless LAN?
Can VRPN be of any use out here ?

Re: Connecting OpenVibe with BCILAB using labstreaminglayer


This would require building from sources? It doesn't seem to be part of the binaries of Openvibe 0.17.

Re: Connecting OpenVibe with BCILAB using labstreaminglayer

We managed to setup OpenVibe 0.17 with the GIPSA extension 2.1 compatible with this version. However, we are not able to "connect" and "play" the Actichamp with the OpenVibe Acqusition Server. The following is the error log: [ INF ] Connection succeeded ! [ INF ] Starting the acquisition... [ INF ] ...

Verification of EEG signals

Hi, We had recorded EEG signals using the Actichamp System and OpenViBE Acquisition server. We would like comments on the recorded EEG signal which can be viewed in EEGLAB as to whether: a) The signal is standard EEG or noise. b) Can this recording be used for further analysis for the paradigm descr...

Connecting OpenVibe with BCILAB using labstreaminglayer

Hi, We wanted to use EEG data recorded from the BrainProducts ActiChamp EEG system for online analysis in BCILAB. http://sccn.ucsd.edu/wiki/BCILAB Apparently, this can be done using Lab Streaming Layer https://code.google.com/p/labstreaminglayer/ . LSL provides a version of the OpenVibe Acquisition ...

Re: [STICKY] Gipsa-lab OpenVibe extensions

There seems to be an issue with using the GIPSA extensions for OpenVibe with the BrainProducts ActiChamp EEG amplifier. After installing the GIPSA extensions, using the executable gipsa-setup-main-1.6.exe, if we run the OpenVibe acquisition server, the BrainProducts ActiChamp does not appear in the ...

Repositioning Emotiv Electrodes to cortical region for MI

We are working on building a motor imagery based BCI system. At the moment, we are constrained to use the Emotiv Headset as our acquisition device. Going through available literature, we infer that the Emotiv system is sub-optimal in capturing motor imagery EEG due to absence of electrodes in the co...
