LibEMG: An Open Source Library to Facilitate the Exploration of Myoelectric Control
Bibliographic record
Abstract
Myoelectric control has been used predominantly in the field of prosthetics, but is an increasingly promising hands-free input modality for emerging consumer markets such as mixed reality. Developing robust machine learning-enabled EMG control systems, however, has historically required substantial domain expertise. This has presented a significant barrier to entry for researchers, impeded progress in EMG-based interaction design, and contributed to the perception that such systems lack the robustness and intuitiveness required for real-world use. To overcome these challenges, we present LibEMG, an open-source Python library for performing offline EMG analyses and developing online EMG-based interactions. By abstracting the challenges and nuances surrounding myoelectric control, including hardware interfacing, data acquisition, feature extraction/selection, classification, post-processing, and evaluation, we eliminate many of the significant barriers limiting the exploration of this technology. Combining expertise from the prosthetics and human-computer interaction communities into a shared library, extensive examples, and documentation, we provide researchers with an accessible tool to accelerate research and improve reproducibility in myoelectric control. In doing so, we aim to facilitate the exploration of this technology, particularly outside prosthesis control, to unlock its potential as a widely applicable hands-free input modality.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
