**[Important Announcement]** ------------------------------------------------------------------------ Due to COVID-19, the award ceremony of the 2020 International BCI Competition has been canceled, unfortunately. Each participant will receive the certificate of the award individually via e-mail. The organizing committee of the competition received many inquiries from the participants through e-mail. After discussion by committee members, we decided not to open the label for the test dataset to the public. It will remain private for the next competition. **2020 International BCI Competition** ------------------------------------------------------------------------ ***Call for Competitors*** We invite competitors for the 2020 International BCI Competition. We encourage competition participation on any topic of interest to the competition tracks. Interdisciplinary topics that will attract a significant cross-section of the community are highly encouraged. Below you will find a brief summary of competitions. For any questions, please contact the 2020 International BCI Competition organizing committee (bcicompetition2020@gmail.com). All prizes are tentative and depend solely on the organizing team of each competition and the corresponding sponsors. ----------  **Description of Competition Datasets** Track 1.
