CVR-BBI

CVR-BBI enables multi-user collaborative brain-to-brain interface experiments through electroencephalogram (EEG) data collection, interactive multisensory stimulus management, and real-time EEG analysis within virtual reality environments.

Key Features:

• Multi-user collaborative paradigm management: The server manages multi-user collaboration paradigms for brain-to-brain interface experiments.
• EEG data collection: The client collects electroencephalogram data from users participating in collaborative experiments.
• Interactive multisensory stimulus management: The client manages interactive multisensory stimuli within the virtual reality environment.
• Real-time EEG analysis: The server performs real-time analysis of collected EEG data.
• Collaborative decoding: The platform supports collaborative decoding of brain signals, which outperforms individual decoding.

Scientific Applications:

• Brain-to-brain interface research: Enables in-depth exploration of cross-brain information exchange between multiple users.
• Collaborative intelligence research: Enhances understanding of collaborative intelligence and brain collaboration.
• Steady-state visually evoked potential paradigm evaluation: The platform was evaluated using the SSVEP paradigm to validate effectiveness in collaborative settings.
• Cognition research: Facilitates study of brain collaboration and cognition in multi-user virtual reality environments.

Methodology:

CVR-BBI consists of a client-server architecture where the client enables user participation in collaborative experiments, EEG data collection, and interactive multisensory stimulus management in VR, while the server manages multi-user collaboration paradigms and performs real-time EEG analysis. Collaborative decoding was evaluated against individual decoding using the SSVEP paradigm.
