This study demonstrates robust surface electromyography (EMG)-based gesture interfaces using user-independent hand gestures. These findings advance EMG gesture interaction technology for broader applications.

Area of Science:

  • Biomedical Engineering
  • Human-Computer Interaction
  • Rehabilitation Engineering

Background:

  • Surface electromyography (EMG) offers a non-invasive method for human-computer interaction.
  • Developing robust EMG-based gesture interfaces remains challenging due to inter-user variability.
  • Existing gesture recognition systems often require extensive user-specific calibration.

Purpose of the Study:

  • To investigate the feasibility of creating robust EMG-based gesture interfaces.
  • To establish user-independent gesture command sets with high discriminability.
  • To validate the performance of these gesture sets in online, real-world scenarios.

Main Methods:

  • An offline experimental scheme was designed to extract user-independent hand gesture sets from 23 classes.

  • Gestures were selected based on class separability, reliability, and low individual variations.
  • Three online experimental conditions (same-user, multi-user, cross-user) were conducted to test interface robustness.

    • Main Results:

    • User-independent gesture sets with high class separability and reliability were successfully extracted.
    • Online experiments demonstrated the feasibility of robust EMG-based gesture interfaces using the recommended sets.
    • The proposed method showed promising performance across different user and testing conditions.

    Conclusions:

    • The study confirms the viability of building robust EMG-based gesture interfaces.
    • The developed user-independent gesture sets are effective for reliable gesture recognition.
    • These results support the advancement and adoption of EMG gesture interaction technology.
