The analysis of user experience (UX) is based on the combined investigation of the individual perceptions, the perceived comfort factors, as well as the human factors. Such experience cannot be objective- ly measured, but requires a variety of ways to capture the user-related knowledge and to define a set of expe- rience-based descriptions to elicit the non-measurable, intangible conditions. UX analysis is helpful to both support interaction as well as to prevent and reduce human errors, with consequent advantages for product quality, company productivity, and users’ wellbeing and safety. Traditionally, UX is fully analyzed on physi- cal prototypes, where the physical and mental workload could be tested and measured by involving sample users. Nevertheless, building physical prototypes increases development cycle times and costs, and provides a late assessment. On the other hand, virtual prototyping can anticipate numerous design issues, but hardly inte- grate the analysis of human factors. Thus, there is a strong need for integrating UX monitoring in the design and verification stages of industrial products and processes by coupling advanced simulation techniques and user monitoring tools. This paper explores how to assess UX during product and process design by digital manufacturing tools. It provides an overview of the scientific state of art on the most common methods and tools to support the human-centered design and presents the results of a survey on more than 100 scientific and industrial papers on international journals and relevant conferences, focusing on the existing methods, tools and applications on the UX assessment to be used in product and process design by researchers and companies. The research also identifies the milestone references to support the UX assessment within indus- trial practices, also including ubiquitous computing, wearable technologies and low-cost connected devices, and points out the main open issues.
