    This study introduces a plug-and-play, zero-training brain-computer interface (BCI) for P300 spellers. This novel system achieves high accuracy in real-time single trials without user calibration, enabling practical BCI applications.

    Area of Science:

    • Neuroscience
    • Computer Science
    • Biomedical Engineering

    Background:

    • Practical brain-computer interfaces (BCIs) often require extensive user-specific calibration and multiple trials.
    • This limits the real-world applicability of P300-based BCIs.

    Purpose of the Study:

    • To develop and validate a plug-and-play, zero-training P300 BCI system.
    • To enable real-time control of devices in a single-trial setting without prior user adaptation.

    Main Methods:

    • Utilized a pre-trained xDAWN spatial filter and a deep convolutional neural network.
    • Implemented a zero-training approach, eliminating the need for subject-specific calibration.
    • Tested the system in real-time for controlling an Internet of Things (IoT) device.

    Main Results:

    • Achieved a real-time decoding accuracy of 85.2%, comparable to an offline accuracy of 87.8%.
    • Identified key parietal and occipital electrodes for high-accuracy, low-density BCI configurations.
    • Demonstrated the feasibility of single-trial P300 BCI operation without stimulus repetition.

    Conclusions:

    • The developed system validates a fully pre-trained, zero-training P300 BCI for real-time, single-trial use.
    • Offers practical insights for creating scalable, robust, and user-friendly BCI systems.
    • Highlights the potential for immediate deployment of P300 BCIs without user-specific training.
