ABSTRACT
This chapter presents results of three projects aiming to provide the requirements for enabling elderly people to stay longer in their flats or houses before moving to senior citizens’ residences or nursing homes. Internet of Things (IoT) refers to a technology designed to increase comfort and quality of life, enabling new ways of interacting with people and things. In IoT systems, devices can communicate with each other over the Internet and learn from each other, devices that are equipped with sensors can perceive the environment, and the sensor data can be read out from anywhere. IoT systems are at the verge of becoming increasingly important in the health context. The software system using big data methods recognizes deviations from the normal daily routine based on vital signs and activity data.
