Smart technologies for COVID-19 indoor monitoring

COVID-19 pandemic has affected every aspect of our life significantly, from work and education to healthcare and entertainment. In order to reduce its spread, safety guidelines have to be followed both indoors and outdoors. In this chapter, the focus is on scenarios related to indoor safety monitoring. The following aspects relevant to indoor COVID-19 protection will be considered: (1) checking whether visitor wears protective mask, (2) body temperature check, (3) social distancing, (4) limited person number indoors, (5) automatic touch-free hand sanitization, and (6) tracing contacts involving infected persons. As research outcomes, several case studies developed at the University of Niš, Faculty of Electronic Engineering in Serbia, will be presented, relying on state-of-the-art smart technology: IoT devices, smartphones, computer vision, semantic knowledge representation, augmented reality, robotics, and blockchain.
