Safety in the workplace is an important theme in today’s society. METI aims to realize safe working environments, adopting the paradigm of a “smart environment”: a physical locations equipped with sensors, interconnected by a network, used to perform a continuous monitoring of the environment and of the people, to identify possible risk factors and prevent casualties.

METI is based on a methodological and technological framework that (i) includes integrated devices in the environment, (ii) provides information about context-aware recognizing the people and the context in which they are located, (iii) can be customized, (iv) is adaptive because it changes according to situations, and (v) is able to anticipate the needs of people. All these features are essential to meet the need for safety in the workplace. The most important technologies used are Wireless Sensor Network and Body Sensor Network.

Sensors are able to retrieve information about the environment and people who are inside it, and when necessary, they are able to perform computations and to interact each other. The resulting monitoring activity is adaptive with respect to a specified context of use.

The objects of the work environment are able to localize themselves, and having the perception of the physical environment, to make surveys and measurements, communicating with each other and with people to support them in their work and to avoid dangerous situations.

On the basis of information derived from monitoring, for the safety goal, METI allows the interaction between people, objects and environment, that is essential to provide all the information necessary to anticipate and manage risks.
