Today, people are increasingly interacting with technology. This interaction is done through a wide variety of interfaces, ranging from a control panel of a nuclear power plant to a computer to access the internet or the screen of a mobile phone. Improving the usability of these man-machine interfaces (HMI) has an important social and economic impact. On the one hand, it guarantees social integration and the quality of life of people, by reducing the rejection that users may have with certain interfaces (mobile, web, etc.). In addition, it allows to improve the performance and productivity of companies, in which a significant amount of resources and tasks are related to the use of HMI.
