Wearable HMI definition, development and validation for collaborative environment in industrial processes in the context of Industry 4.0.

The latest technological innovations, the changes in market conditions and the transformation of factories from digital to intelligent has led to a greater competition between companies. In fact, organizations increasingly show the need to satisfy a large number of consumers, approaching the so-called mass production. In addition, companies aim to reduce costs, improve product quality and create efficient work environments. This has produced the effect of an increasingly frequent introduction in the collaborative environments of factories of robots, that work in close contact with operators, giving them support in daily operations. From here the concept of Smart Factory develops, in which the predominant part is made up of the Cyber-Physical Systems, i.e. systems for which each physical object is associated with a digital one, thanks to which it is possible to collect, store and process data, and consequently to make the processes more efficient. In order to connect to the CPS, it’s necessary to have a Human-Machine interface, which allows humans to communicate with machines and robots via the interface of a device. The objective of the thesis is to develop a graphic interface for smartwatch that represents two of the Use-Cases of the ICOSAF project. The web application is designed to support the interaction between humans and robots within a collaborative space of the intelligent factory for the execution of daily tasks. The paper shows the various steps concerning the tools and technologies used, such as the Android Studio platform in its Wear OS variant and, subsequently, the implementation of the project and the use of libraries for the development of the most important application features. In conclusion, the results achieved and the possible future improvements will be analyzed.
