Device-Free Hand Gesture Recognition with ESP32 Wi-Fi CSI: Formal Doppler Modeling and Lightweight Deep Learning

2026-02-02

Abstract excerpt

Wi-Fi Channel State Information (CSI) has emerged as a powerful modality for device-free gesture recognition, enabling human–computer interaction without cameras or wearables. Existing systems, however, often rely on PC-class network interface cards (NICs) and computationally heavy neural networks, which limits deployment in resource-constrained IoT settings. This paper presents a complete, mathematically grounded...
