Lightweight Test-Time Adaptation for EMG-Based Gesture Recognition

arXiv:2601.04181v2 Announce Type: replace Abstract: Reliable long-term decoding of gestures from surface electromyography (EMG) is hindered by signal drift caused by electrode displacement, muscle fatigue, and/or posture changes. Although modern models achieve high intra-session accuracy, their performance often degrades substantially across recording sessions. Existing approaches to mitigate this problem typically rely on large training datasets or computationally intensive pipelines that are unsuitable for energy-efficient wearable devices. We propose a lightweight test-time adaptation frame

Why this matters
Why now

The proliferation of wearable AI devices and the increasing demand for seamless human-computer interaction necessitate more robust and adaptive sensor technologies that can perform reliably outside of controlled lab environments.

Why it’s important

This breakthrough addresses a critical bottleneck in the real-world application of EMG-based gesture recognition, enabling more reliable and energy-efficient control interfaces for everyday use.

What changes

The ability to achieve reliable, long-term EMG decoding with lightweight, test-time adaptation lowers the barrier for widespread adoption of gesture control in resource-constrained edge devices.
