Soft Active Electromyography Interface for Machine Learning-Enabled Silent Speech Recognition

The paper presents a soft, active electromyography (EMG) interface that enables word-level silent speech recognition (SSR) using machine learning. The device, worn on the hand, employs a fingertip electrode positioned near the lips to acquire EMG signals only when needed, and incorporates liquid metal interconnects, transparent flexible printed circuit electrodes, and elastomer encapsulation for mechanical stability during finger motion. A deep neural network trained on these stable signals achieved a mean accuracy of 97.2 ± 1.3 % across three subjects for a 30‑word vocabulary, and real‑time drone control demonstrated its practicality in noisy, privacy‑sensitive environments.

Pose2Muscle: Structured Spatio-Temporal Decoding for Discrete Muscle Activity Estimation from Human Pose

Pose2Muscle is a pose-driven framework that estimates discrete muscle activity states without requiring surface electromyography (sEMG) during inference. It reformulates muscle estimation as a structured prediction problem, using multi-scale spatio-temporal attention and a directed acyclic graph-based decoder to capture motion patterns and maintain multiple candidate hypotheses. The authors introduce the PoseEMG-43 dataset, comprising 2,992 movement instances from 43 daily-life actions performed by 14 participants, and demonstrate that Pose2Muscle outperforms baseline methods with high accuracy and correlation metrics.

On-Device Neural Architecture Search

arXiv:2606. 24900v1 Announce Type: new Abstract: This paper proposes a new approach to near-sensor computing, in which a lightweight Neural Architecture Search (NAS) is performed directly on the deployment device to find the best tiny neural architecture for analyzing the real-time data acquired through sensors.
