Usability Testing on Tractor’s HMI: A Study Protocol
No full textThe success of a human-machine interface (HMI) heavily depends on its usability. An highly usable interface allows the user to more easily achieve his/her goals and in general have a better User eXperience (UX). In work environments, a structured and ready-to-use usability testing protocol can encourage companies to carry out this type of study and focus on UX from the early design phases. Even though numerous methods to test usability exist, industrial companies still have great difficulties to apply them and choose the best ones for the specific purposes. They should be guided into the analysis by a universal step-by-step approach, which helps also not experienced designers selecting the most reliable and useful methods among the available ones. In this direction, the paper proposes a structured protocol to focus on UX and guide companies in testing setup, execution and debriefing in an easy and quick way. Checklists are defined to help during user testing and assure its success. As a consequence, end users can be easily involved to give an added value in design problems identification. The novelty of this paper is the definition of a ready-to-use study protocol that can also be used by non-usability experts, in order to make them familiar with UX analysis and extend this practice also in industrial HMI design. As validation, the proposed protocol was applied to the design of interfaces for agricultural tractors during two different stages of the HMI redesign process
A framework to design smart manufacturing systems for Industry 5.0 based on the human-automation symbiosis
Full text linkThe concept of Industry 5.0 (I5.0) promotes the human-centricity as the core value behind the evolution of smart manufacturing systems (SMSs), based on a novel use of digital technologies in the design and management of modern industrial systems to take up the socio-technical challenges. In this context, the paper proposes a Smart Manufacturing Systems Design (SMSD) framework enabling I5.0, based on the human-automation symbiosis. Thanks to an 'Augmented Digital Twin' (ADT) able to integrate and digitize all the entities of the factory (i.e. machines, robots, environments, interfaces, people), AI-driven applications can be built to support the user domain and make people and machines co-evolve thanks to a systematic data sharing between physical and digital assets (e.g. digital twin, virtual mock-ups, human-machine interfaces), optimizing factory productivity and workers wellbeing. In this framework, machines and humans can both generate knowledge and learn from each other, generating a virtuous co-evolution, supporting the understanding of the human-machine interplay and the creation of an effective collaboration between people and SMSs. The framework was conceived and validated involving four industrial companies, belonging to diverse sectors, interested in overcoming the current limits of I4.0 lines by including the human factors for future SMS management
