StimUSTO

Stimulus presentation platefrom for real time EEG based Brain-Computer Interface experiments, developed at the LARESI Lab, USTO-MB. Algeria (work in progress)

  • Works on top of OpenVibe platefrom, which guarantees real-time EEG signal processing.
  • Developed using Qt framework with C++.

Stimulations

The main goal of this project is to facilitate novel High-Speed Stimulus presentation development for Brain-Computer Interface research and applications, by using an Open Source Cross-Platform native GUI framework.

ERP SSVEP Hybrid
Signel character spellers Square ON/OFF ERP & SSVEP
Face / Inverted Face speller Sampled Sinusoidal Stimulation (with OpenGL)
Colored Face/Inverted Face

Installation

Using Qt creator

Before building the project, make sure Qt (version 5.x) and Qt creator are installed. then load the project and open it in Qt create. After that build it as any other Qt project.

Usage

Before any use, open OpenVibe Acquisition Server (for reading EEG signal in real-time) and OpenVibe Designer (for real-time signal processing)

with GUI

The GUI will pop up after succeful build, after that you can re-open it by double click on the StimUSTO.exe in the folder build\release\release folder. The configuration panel is what is shown first, there the Stimulation paradigm and configurations are edited and started.

  • Connect to OpenVibe acquisiton server by clicking on connect (with default configurations of host and port). This connection is used for passing event markers to the OpenVibe Acquisition Server via a TCP connection.
  • Modify the parameters as suitable to your experiment needs.
  • Click on Init[Speller|SSVEP|Hybrid] to init one of the paradigm.
  • Click on Start at the control panel to start experiment.

No GUI - CLI

This functionality requires specifying a config file in a JSON format for experiment configurations with the --no-gui and --file options (a config example is found in the /config folder). Here the connection to OpenVibe acquisiton server is done automatically.

in command prompt type the following command:

StimUSTO.exe --nogui True --file "/config/default_.json"
