The paper analyses thematic areas of the circular economy, reflecting the goals of the European Green Deal. The purpose is to explore guidelines, tools, and assessment criteria for how the design and manufacturing of furniture can contribute to a climate-neutral Europe by 2050. EU is the leading promoter of environmental policies and thus pushes towards disseminating the circular economy paradigm in the furniture sector, identifying current trends and strategies. In addition to product design, system design solutions are emerging to support new service-oriented business models. The adoption of the circular economy requires a change of business, territorial, and individual visions and to rethink ways of producing and consuming. By developing the knowledge base for greener and more innovative manufacturing processes, it is possible to understand which strategies are most promising for the sector and to plan for a sustainable and more democratic European furniture design culture.

Digital technologies have been widely adopted in the Cultural Heritage sector over the past few decades. Many museums, galleries, historic sites, and other cultural institutions now host multimedia exhibitions or temporary installations in which technology plays a significant role in shaping the visitor experience. Among these, Extended Reality (XR) technologies, including Virtual Reality (VR) and Augmented Reality (AR), have been extensively applied and studied. Spatial Augmented Reality (SAR), a branch of AR, has also become increasingly present in cultural contexts; however, the academic literature still lacks a comprehensive and systematic review of studies addressing its use. Furthermore, various methods of inquiry and evaluation have been employed to assess SAR applications in cultural institutions, both from the perspective of visitors and from that of cultural practitioners and stakeholders. This scoping review, conducted in accordance with the PRISMA guidelines, collected a total of 47 papers that introduce the academic perspectives on SAR in the cultural domain. It reports its definitions, applications, documented benefits, and the different evaluation approaches identified in the literature. Through a snowball sampling methodology, the collection has been expanded to include 33 additional studies. After the screening process, the authors reviewed 34 papers, presenting the gaps identified in the literature and outlining suggested directions for future research.

The chapter portrays the state of the art of AI-infused products, that while offering exciting novelties in terms of user experience, offer present difficulties to exploit their full potential. The core and peculiar qualities of AI-infused products are primarily explored. The chapter further frames the current and unique challenges they present to their design and new interaction paradigms they introduce in the user experience. The chapter finally questions the necessity of a rethinking of traditional UX evaluation methods to accommodate these emerging design challenges.

Industrial design intended as cultural heritage is witnessing a period's industrial production and creative thought; this legacy needs to be shared with a broader audience. The Milan area is full of studios and ateliers, where most Italian design projects were born. Even though they are no longer operating, these locations are still linked to the creative process and convey the atmosphere of the golden age of Italian design. Design research is essential in investigating archives' potential in constructing historical narratives and new research paths and learning tools. The paper describes two case studies for enhancing Design Culture through digital technology. A digitisation project for the archive of the famed Italian modeller Giovanni Sacchi to link heterogeneous data – sketches, technical drawings, images, physical models – to create an overall view of the design process and highlighting the creative thought. The second describes LfAC, a mobile location-based application designed to lead visitors to discover Achille Castiglioni's projects in downtown Milan: works are valorised and brought back to life through contextual contents delivered to visitors' smartphones.

The chapter frames the AIXE (AI user eXperience Evaluation) scale, a statistically validated questionnaire to assess the UX of AI-infused products, describing its development process as well as its validation. AIXE is composed by 33 questions with 4 ordinal Likert-scale answers, organized around 12 descriptors related to the UX of the target systems. The questionnaire is meant to be proposed to the intended users of AI-infused products to quantitatively analyse the user experience they convey. The chapter further illustrates how the scale can be applied, its limitations and future opportunities.
