Contactless health monitoring refers to the process of measuring and tracking vital health parameters without the need for physical contact with the person being monitored. This approach typically utilizes advanced technologies such as remote photoplethysmography (rPPG), computer vision, and machine learning algorithms to gather essential health data from a distance. This remote vital signs monitoring is particularly useful for telehealth platforms, healthcare providers, fitness and wellness companies, insurance providers, and corporates, as it can enhance patient care, improve health outcomes, and facilitate remote health management.
