HealthHand A Visual Interface for eHealth Monitoring The digitization within the healthcare sector is an extensive topic for multiple ICT technologies, such as Cloud Computing, Internet of Things (IoT), and Artificial Intelligence. Over the past years, there has been an increasing interest in the storage, evaluation and visual representation of medical data. This led to a substantial amount of independent eHealth technologies, that are primarily concerned with information gathering and management. However, the multitude of existing tools makes it is difficult for the user to understand global relationships between different management systems. Therefore, we present HealthHand an IoT system for monitoring vital and administrative data in the digital twin of an intensive care unit (ICU). The main goal of our system is to summarize and process realtime data in order to assist medical experts such as physician, headnurses or controllers in their daily tasks. HealthHand achieves this by providing a visual interface for the management and analysis of different medical data sources.

Understanding Ehealth Application Utilizing Internet of Things (IoT) Technologies EHealth applications make room for exchange of information between medical professionals and patients, hospitals to hospitals, lower cost, increased scope and extent of medical facilities, as well as improving the quality of services. Despite all these advantages, healthcare system is still being challenged with the factors such as increased number of ageing population, need for reduced cost of health services, the shifting of healthcare services from providercentric to patientcentric, the type of new diseases available and their treatments. All these require Internet of Things (IoT) for its transformation. This work seek to explore Internet of Things in eHealth domain and determine how its operations can transform healthcare application system. We examined technological and application trends in healthcare, Convergent eHealthIoT Works, attacks and issues in eHealth utilizing Internet of Things technologies, applications of Internet of Things (IoT) in eHealth, as well as challenges and open problems in the eHealth domain.
