    This study introduces the Cross-Subject Lifelong Network (CSLN) for estimating hand movements using surface electromyographic (sEMG) signals. CSLN improves cross-subject generalization and prevents model forgetting in human-machine interfaces.

    Area of Science:

    • Biomedical Engineering
    • Machine Learning
    • Human-Computer Interaction

    Background:

    • Surface electromyographic (sEMG) signals offer a non-invasive method for hand kinematics estimation in human-machine interfaces.
    • Existing subject-specific models lack broad applicability, while current cross-subject methods struggle with both new and existing users.
    • Challenges include limited generalization and effective user adaptation in cross-subject sEMG analysis.

    Purpose of the Study:

    • To develop a novel method for robust cross-subject estimation of hand kinematics from sEMG signals.
    • To enhance the generalization capabilities of sEMG-based models across diverse users and time scales.
    • To address the limitations of current subject-specific and cross-subject approaches in human-machine interfaces.
