Area of Science:

Biomedical Engineering
Neuroscience
Human-Computer Interaction

Background:

Neurotechnological interfaces enable direct interaction with neurological signals.
Surface electromyography (sEMG) is crucial for myoelectric control systems, primarily in rehabilitation.
Existing sEMG applications often lack generalizability across different users and time points.

Purpose of the Study:

To introduce a novel, fine-grained sEMG dataset for human-machine interaction research.
To facilitate the development of advanced myoelectric interfaces beyond rehabilitation.
To evaluate the feasibility of using sEMG for classifying key presses during typing.

Main Methods:

Collected 16-channel bilateral sEMG recordings and corresponding key logs from 19 participants.
Data acquired across two separate sessions for each individual.
Utilized baseline machine learning models for performance evaluation.

Main Results:

High classification accuracy was achieved within individual sessions.
Inter-session and inter-subject classification accuracy were significantly lower.
Performance drop indicates challenges in generalizing myoelectric control models.

Conclusions:

The developed sEMG dataset provides a valuable resource for advancing myoelectric interfaces.
Generalizing myoelectric control across different sessions and individuals is a key area for future research.
Further development is needed to overcome limitations in real-world, adaptable human-machine interaction systems.
