Usability, user experience and mental workload in a mobile Augmented Reality application for digital storytelling in cultural heritage

Augmented Reality (AR) has become an increasingly used technology to support and enhance the enjoyment of cultural heritage. Particularly relevant is its importance for digital storytelling: by framing a portion of a fresco or painting with a smartphone, an AR mobile application can provide contextually relevant information, also in the form of multimedia content, that can help the user to understand the story and meaning behind the images. In this type of application, human factors are of fundamental importance for the effectiveness of the narrative: a mobile AR application must avoid distracting the user’s attention from the content in order to encourage a good level of concentration and immersion. The case study presented in this paper deals with a mobile AR application developed to guide visitors in the interpretation of the frescoes inside the Basilica of Saint Catherina of Alexandria in Galatina. The aim of the study is the analysis of the relations among usability, user experience and mental workload factors in AR-based digital storytelling

Gestational age and hospital utilization : three-years follow-up of an area-based birth cohort

OBJECTIVE: To investigate differences by gestational age in emergency department visits and re-hospitalizations during the three years following childbirth discharge. METHODS: We performed a historical cohort study in Lazio Region, Italy, for infants born in 2007-2008 to resident mothers. Health administrative data were used. Analysis was performed by multinomial logistic regression. RESULTS: Of 90 545 infants, more than 50% had at least one emergency department visit, and 18.8% at least one re-hospitalization. After the exclusion of infants with congenital anomalies, relative risk ratios of re-hospitalization and, to a lesser extent, of emergency department visits increased by decreasing gestational age; the two events were also higher for mothers ≤35 years of age, with low education and of Italian nationality. Residency outside the metropolitan area was associated with an increased risk of re-hospitalization and a decreased risk of emergency department visits. CONCLUSION: During the three years following childbirth discharge, re-hospitalizations and, to a lesser extent, emergency department use are inversely related to gestational age at birth; socio-demographic factors have an effect on the risk of infant use of hospital resources independent of gestational age

Virtual Reality and Spatial Augmented Reality for Social Inclusion: The “Includiamoci” Project

Extended Reality (XR) technology represents an innovative tool to address the challenges of the present, as it allows for experimentation with new solutions in terms of content creation and its fruition by different types of users. The potential to modulate the experience based on the target audience’s needs and the project’s objectives makes XR suitable for creating new accessibility solutions. The “Includiamoci” project was carried out with the aim of creating workshops on social inclusion through the combination of art and technology. Specifically, the experimentation involved ten young people between the ages of 28 and 50, with cognitive disabilities, who participated in Extended Reality workshops and Art Therapy workshops. In the course of these activities, the outputs obtained were two: a virtual museum, populated by the participants’ works, and a digital set design for a theatrical performance. Through two tests, one on user experience (UX) and one on the degree of well-being, the effectiveness of the entire project was evaluated. In conclusion, the project demonstrated how the adopted solutions were appropriate to the objectives, increasing our knowledge of UX for a target audience with specific user needs and using XR in the context of social inclusion

Work environment, volume of activity and staffing in neonatal intensive care units in Italy: results of the SONAR-nurse study

Neonatal units' volume of activity, and other quantitative and qualitative variables, such as staffing, workload, work environment, care organization and geographical location, may influence the outcome of high risk newborns. Data about the distribution of these variables and their relationships among Italian neonatal units are lacking

Il sonetto eucaristico di Guglielmotto d’Otranto, rimatore del sec. XIII

Il saggio propone, attraverso l'esame della tradizione testuale, l'edizione critica del sonetto "Salve, sancta veraze Ostia sacrata" attribuito a Guglielmotto d'Otranto, rimatore del secolo XIII e personaggio dai confini biografici e storici incerti. La lirica è di tutta rilevanza per la datazione, per il tema teologico trattato, per le particolarità metriche e per le vicende stesse della tradizione manoscritta
