We’re thrilled to share a major milestone in the BINGO project: the data collection phase for the full EEG dataset is now complete!
Over the course of the project, our research team worked with carefully recruited healthy participants across multiple recording sessions to capture imagined speech signals tied to the complete NATO phonetic alphabet (including cross-linguistic experimental setting as well). Recordings were conducted on three separate days to capture session variability — a real-world challenge for EEG-based decoding. This dataset represents one of the most comprehensive public resources in the field to date, with high-density multi-channel recordings that reflect both within-subject and between-session dynamics.
Completing this stage wasn’t just about logistics — it involved:
- Rigorous experimental design to ensure data quality
- Ethical oversight to protect participant well-being and data privacy
- Advanced preprocessing to prepare EEG signals for algorithmic interpretation
- Documentation that will enable reuse and comparability across studies
This milestone sets the stage for the next critical phases of the project: analysis, benchmarking, and scientific competition. With the data fully acquired and curated, researchers and competitors alike will be able to dive deep into algorithm development and validation.
We couldn’t have reached this point without the dedication of our participants and research team. Their contribution is helping push the boundaries of neurotechnology research.
Stay tuned — with data collection complete, the exciting work of decoding imagined speech begins in earnest!
