mmHSense: Multi-Modal and Distributed mmWave ISAC Datasets for Human Sensing

This article presentsmmHSense, a set of six labeled mmWave datasets to support human sensing research within Integrated Sensing and Communication (ISAC) systems. The datasets can be used to explore mmWave ISAC for various end applications such as gesture recognition, person identification, pose estimation, and localization. Moreover, the datasets can be used to develop and advance signal processing and deep learning research on mmWave ISAC. This article describes the testbed, experimental settings, and signal features for each dataset. The datasets cover both Wi-Fi and 5G signals. Furthermore, the utility of the datasets is demonstrated through validation on different downstream tasks such as pose estimation, gesture recognition, localization, and person identification. In addition, we demonstrate the use of parameter-efficient fine-tuning to adapt ISAC models to different tasks, significantly reducing computational complexity while maintaining performance on prior tasks.
