“Sail with Columbus” is an interactive and tangible storytelling project designed for a Nautical Museum. Its goal is to communicate to the museum visitors how the medieval men sailed in the past. We aim to reach this goal thanks to the interaction between participants and several augmented objects. Communicating a complex cultural practice, such as the art of navigation in the past, is a new challenge in the Tangible Narratives field. This raised requirements and research issues that the project tried to address. In this paper we present the conceptual design, the project mock-up and its preliminary evaluation.

This paper analyzes the Italian job market of UX designers through a qualitative analysis of 100 randomly selected job announcements. We employed a deep qualitative analysis for extrapolating the dimensions that characterize the professional figure of a UX designer. Our analysis reveals as the UX designer is considered a technical figure closer but often distinct from the professional figure of the front-end software developer. Although software development competence is still required in some cases, in several others, the core aspects of User-Centred Design seem to be correctly understood, and the required competencies and skills denote a relatively high UX maturity. On the other hand, the request for more straightforward web design is still high, and the UX designer’s role often overlaps (or it is confused) with the role of the graphical designer. Furthermore, the Italian companies seem not yet ready to catch the strategic role that UX can play in aligning with business and marketing areas. Although our main objective for this study was to assess and align academic training for UX designers, we believe that it might also be the basis to better advocate the UX design profession to companies.

Software defines our everyday experiences! Communication in families as well as in the workplace is largely software mediated. The choices we make, from the news articles we read to the movies we watch and the people we date, are to a large extent software supported. Personalized news portals, navigation systems, social media platforms, shopping portals, music streaming services, and dating apps are only some examples of systems that affect what we experience, think, and do. Improvements in human computer interaction have led to a wide universal adoption of these systems in many areas. Artificial intelligence, learning about the users and their preferences, and striving for simplification in interaction, reduces the need to make active decisions and thereby removes chance and choice. Will this lead to highly optimized systems – that apparently work great for the user, but at the same time end the element of randomness and serendipity in our lives? Simplified content creating, recommender systems and augmented reality are drivers for this. Can interactive human centered artificial intelligence help to keep the user in control or is this just an illusion?

Many businesses and web portals adopt Recommender Systems (RSs) to help their users to tame information overload and make better choices. Despite the fact that RSs should support user decision making, academic researchers, when evaluating the effectiveness of a RS, largely adopt offline rather than live user studies methods. We discuss the relationships between these evaluation methods by considering a tourism RS case study. We then suggest future directions to be taken by HCI and RS research to better assess the user’s value of RSs.

End-user development (EUD) is widely used today for the personalization of the most diffused commercial virtual assistants (VAs), both for the configuration of VA-controlled smart environments and the definition of automatic behaviours. However, EUD is not yet exploited to its potential. In this paper, we present the results of a long-time use of VAs in our homes: we compare the most known VAs and discuss a set of challenges that we identified and that can guide the future directions of Human-Computer Interaction research in this field.

Voice disorders occur when voice quality, pitch, and volume differ or are inadequate for an individual's age, gender, cultural background, or geographic location. These are due to inherent internal and/or external factors, such as vocal cord damage, brain damage, muscle weakness, or vocal cord paralysis that often damage the vocal folds. Commonly the age range of the patients is 4-6 years old. To overcome these problems, speech therapy is needed, which consists of a set of exercises aiming to stimulate the child's language. A personalized treatment for each patient should be defined in accordance with the patient's specific problems. Since speech exercises, even if they usually are proposed as games, are often boring for the children and their caregivers, this research proposed the system Pronuntia, which supports all the actors involved in the speech therapy. The automatic acquisition and correction of the speech exercises through the system allows real-time feedback to patients and therapists. Moreover, some AI techniques have been implemented to help therapists in tuning the automatic recognition level of the patient's speech according to the disease severity. A user test involving 5 speech therapists and 5 caregivers has been carried out to evaluate the usability of the system.

Recent research tried involving different end-users in the design of smart things, such as smart watches that sense high temperature, process it, and react by vibrating. Designing new smart things is a lengthy process, which requires exploring what smart things are made of, ideating them, as well as programming them. Engaging children across an entire design process is thereby demanding, e.g., it requires sustained attention and logical reasoning. Engaging children in design at a distance is even more complicated, e.g., there are no reference models. This paper reports on the design of an online workshop, which aimed at engaging children across the entire design process of smart things, of increasing complexity, and at a distance. Children were different for age and gender. An engagement questionnaire was administered to understand whether children were engaged in smart-thing design at a distance. This paper offers a descriptive statistical analysis of the results of the questionnaire, which are discussed to distil lessons for future engaging smart-thing design workshops at a distance.

We compare a data-driven persona system and an analytics system for efficiency and effectiveness for a user identification task. Findings from the 34-participant experiment show that the data-driven persona system affords faster task completion, is easier for users to engage with, and provides better user identification accuracy. Eye-tracking data indicates that the participants focus most of their attention on the persona content while focusing more on navigation features when using the analytics system. The combined results provide empirical support for the use of data-driven personas for a user identification task, which we surmise to be a result of the persona system following a user-centered design paradigm instead of an information-centered paradigm. That analytics system afforded capabilities and insights that the persona system did not suggest that the triangulation of features may lead to a better overall user understanding.

This study investigates COVID-19's impact on the education system. It captures a multidimensional representation of teachers, students, and parents' use of information communication technologies (ICTs) to mitigate this disruption caused by school closures. The study analyzes the evolving influences on individual and collective behaviour amid the pandemic. The methods consisted of a 5-week longitudinal study that included a survey and multiple interviews with the three stakeholder groups. The qualitative and quantitative data yielded the analysis of ICTs usage before and during social confinement. Further to our analysis, we categorize and discuss our findings. We also interpret results to capture design implications and generate a new concept for design. To finalize, we identified students' learning loss and learning variability as pressing issues, despite the availability of technological mediums. We believe that a collaborative learning system could mitigate such a challenge. We believe that such a system could connect students to a teaching community and imbue a sense of togetherness within the context of distance education.

This work focuses on the use of a specific type of visualization to analyze soccer matches and highlight individual players’ goal contributions. An analytic approach in team sports is nowadays considered crucial by both practitioners and other interested parties such as fans or betters. In soccer, the analysis of sequences of passes and shoots can help the analysts understanding some aspects of the performance of players and teams. We show how, through a compact representation of n-ary temporal relationship, users can get a comprehensive view of the evolution of the passes leading to a goal in several matches. The dataset considered in this work contains data from the first 26 weeks of the season 2019-2020 of the Italian major soccer league.
