Embedded Files
During my work, I was involved in the development of softwares and/or librairies dedicated to Brain-Computer Interface research and applications.
So far, our objective was to make these developments available to the community, by distributing these softwares under free and open-source licences.

OpenViBE: An Open-Source Software Platform to Easily Design, Test and Use Brain-Computer Interfaces
OpenViBE: An Open-Source Software Platform to Easily Design, Test and Use Brain-Computer Interfaces
OpenViBE is a free and open-source software platform for the acquisition, processing, classification and display of brain signals (e.g., EEG, MEG, ECoG, ...). The platform consist in a set of software modules that can be integrated easily and efficiently, in order to design real-time applications for neuroscience including Brain-Computer Interfaces (BCI) and neurofeedback.
It is made to be easy, in the sense that by using OpenViBE, it becomes possible to rapidly create a BCI without writing a single line of code.
Indeed, OpenViBE enables users to design a BCI by using only graphical programming, simply by adding and assembling together boxes, each box corresponding to a given processing module (see pictures below)
Fig. 1: Graphical design of a BCI or neurofeedback system using OpenViBE
OpenViBE already proposes various features and processing modules in order to design a BCI, such as:
Processing modules: temporal filters, spatials filters, ICA, windowing, FFT, time-frequency analysis, inverse solutions, etc.
Classification modules: linear discriminant analysis, classifier combination, fuzzy inference systems, etc.
Visualization modules: raw signal, 2D topography, 3D topography, spectrums, etc.
Easy interaction with virtual reality applications
Acquisition from various EEG devices
Ready-to-use BCI: motor imagery based BCI (binary of multiclass, synchronous or self-paced), P300-based BCI, neurofeedback, ...
