Decoding Your Body with Ubiquitous Sensing: Wearable and Contactless Perception for Health and Beyond

As the global population ages, demand for healthcare services is rising. Yet basic services, such as brief check-ups and rehabilitation guidance, remain largely restricted to hospitals and clinics, limiting regular use, especially for patients with chronic conditions. Our research addresses this gap by delivering home-based, affordable care services enabled by ubiquitous, low-cost sensors embedded in everyday devices. Through our designs, patients gain consistent, convenient, and self-service access to essential health services at home. In this paper, we present a case study on the management of chronic respiratory diseases using ubiquitous sensing systems. Specifically, we introduce a ''closed-loop'' management framework spanning basic vital sign monitoring, disease severity assessment, and rehabilitation training guidance.
