Mariana Oliveira is a Master’s student in Physics Engineering at the Faculty of Sciences of the University of Porto (FCUP), currently working on her thesis under the supervision of Luis Pessoa. Her research is part of the ongoing CONVERGE project, which focuses on developing a Radio Frequency (RF) sensing system for human activity recognition and exploring the impact of manipulating the emitted and reflected RF signals in the radio environment.
As a result, Mariana Oliveira got the paper “SpecRF-Posture: Exploring Specular Reflections for Human Posture Recognition” accepted at the IEEE International Mediterranean Conference on Communications and Networking 2024 (IEEE MEDITCOM 2024). The paper was co-authored by Francisco M. Ribeiro, Nuno Paulino, Okan Yurduseven, and Luís M. Pessoa.
This work presents SpecRF-Posture, a novel system for accurate Human Posture Recognition (HPR) using RF signals. SpecRF-Posture leverages S21 parameters within the WiFi-6E frequency range for classification. The system integrates a metal plate to improve posture information extraction by manipulating RF signals through specular reflections. Additionally, SpecRF-Posture achieves beam scanning by mechanically rotating the transmitter, covering the entire metal plate for precise posture recognition. Experimental results show that SpecRF-Posture achieves an accuracy of 99.17% in posture classification, demonstrating its effectiveness. In addition, an RF dataset has been acquired using a software package for automatic data acquisition within the WiFi-6E frequency range, and both the dataset and the software package have been made publicly available.
Congratulations!
