Augmented reality experience: from high-resolution acquisition to real time augmented contents

This paper presents results of a research project "dUcale" that experiments ICT solutions for the museum of Palazzo Ducale (Urbino). In this project, the famed painting the "Città Ideale" becomes a case to exemplify a specific approach to the digital mediation of cultural heritage. An augmented reality (AR) mobile application, able to enhance the museum visit experience, is presented. The computing technologies involved in the project (websites, desktop and social applications, mobile software, and AR) constitute a persuasive environment for the artwork knowledge. The overall goal of our research is to provide to cultural institutions best practices efficiently on low budgets. Therefore, we present a low cost method for high-resolution acquisition of paintings; the image is used as a base in AR approach. The proposed methodology consists of an improved SIFT extractor for real time image. The other novelty of this work is the multipoint probabilistic layer. Experimental results demonstrated the robustness of the proposed approach with extensive use of the AR application in front of the "Città Ideale" painting. To prove the usability of the application and to ensure a good user experience, we also carried out several users tests in the real scenario

ENHANCING ONSITE AND ONLINE MUSEUM EXPERIENCE THROUGH DIGITAL RECONSTRUCTION AND REPRODUCTION: THE RAPHAEL AND ANGELO COLOCCI TEMPORARY EXHIBITION

Leveraging extended reality technology, digital reconstruction, and reproduction of cultural heritage can enable effective solutions to enhance museum experience. Particularly, this paper focuses on virtual reality as a tool to support both onsite and online visits of a temporary exhibition dedicated to Raphael and Angelo Colocci. We present an immersive VR experience of the School of Athens. Within the digital reconstruction of its architecture, two actors provide descriptions of its features and significance, blurring the line between real and virtual. Furthermore, to ensure that visitors can continue to explore the exhibition even after its closure, we developed a virtual tour. Taking advantage of panoramic images and 3D digital replicas, it continues to convey the same cultural contents, preserving the essence of the exhibition. In conclusion, we conducted evaluations of both the experiences to assess their effectiveness and gather insights for further enhancements

Chapter In dialogo con i musei: innovazione e trasformazione digitale per una nuova visione del patrimonio

The 43rd UID conference, held in Genova, takes up the theme of ‘Dialogues’ as practice and debate on many fundamental topics in our social life, especially in these complex and not yet resolved times. The city of Genova offers the opportunity to ponder on the value of comparison and on the possibilities for the community, naturally focused on the aspects that concern us, as professors, researchers, disseminators of knowledge, or on all the possibile meanings of the discipline of representation and its dialogue with ‘others’, which we have broadly catalogued in three macro areas: History, Semiotics, Science / Technology. Therefore, “dialogue” as a profitable exchange based on a common language, without which it is impossible to comprehend and understand one another; and the graphic sign that connotes the conference is the precise transcription of this concept: the title ‘translated’ into signs, derived from the visual alphabet designed for the visual identity of the UID since 2017. There are many topics which refer to three macro sessions: - Witnessing (signs and history) - Communicating (signs and semiotics) - Experimenting (signs and sciences) Thanks to the different points of view, an exceptional resource of our disciplinary area, we want to try to outline the prevailing theoretical-operational synergies, the collaborative lines of an instrumental nature, the recent updates of the repertoires of images that attest and nourish the relations among representation, history, semiotics, sciences

Per un approccio sistemico alla rilevazione, misurazione e valutazione dell'applicazione delle tecnologie digitali alla tutela, gestione e valorizzazione del patrimonio culturale

In vista dell\u2019anno europeo del patrimonio culturale sembra pi\uf9 che mai opportuno riflettere in modo sistemico sullo stato dell\u2019arte nell\u2019applicazione delle tecnologie ICT al patrimonio culturale, anche in rapporto agli effetti eventuali di miglioramento della qualit\ue0 nella tutela e valorizzazione. Data la molteplicit\ue0 e autonomia delle linee di finanziamento a livello nazionale e locale, allo stato attuale non \ue8 possibile monitorare i progetti e la loro efficacia con un\u2019ottica olistica. L\u2019intervento presenter\ue0 i passi fatti finora per la costruzione di un osservatorio, di livello regionale, che si candiderebbe ad essere un riferimento condiviso per la ricerca, per la formazione e per l\u2019applicazione delle tecnologie digitali nelle Marche. In particolare l\u2019aspettativa \ue8 quella di una valutazione e misurazione di efficacia, evitando sovrapposizioni e dispersioni di risorse pubbliche e favorendo lo scambio di soluzioni nella valorizzazione delle best practice

From point cloud data to HBIM for public performance spaces knowledge, management and storytelling: Palazzo Olivieri in Pesaro

The very latest lines of European research in the field of Cultural Heritage are mainly focusing on disruptive global transitions through valueand future-oriented strategies in a green and digital scenario. This approach stems from the concept of Heritage as a unique but nonrenewable resource, featuring multilayer cultural contents (tangible and intangible), and evolving in close correlation with the constantly changing components in the territory. Digitisation is increasingly confirming itself as an enabling factor for many practices involving cultural heritage. With specific regard to the built heritage, digital technologies provide functions that can catalyse and optimally support architecture knowledge and storytelling, which in turn enhance new levels of interaction, and can improve the active conservation and integrated management of heritage asset. Starting from this assumptions, Palazzo Olivieri-Machirelli in Pesaro (Italy) was studied for challenging trials. Nowadays, the historical building is used as a music conservatory thanks to the testamentary legacy of the Italian composer Gioachino Rossini and the homonymous Foundation, and incorporates the Auditorium Pedrotti, which is the focus of this research. Thus, this architecture was selected as a testing case for inventive and immersive experiences as well as for long-term management solutions and systems, which exploit the paradigm of Heritage – or Historic – Building Information Modelling (HIBIM) and the robust technology of Augmented and Virtual Reality (AR, VR), taking advantage of solid base in the survey phase, which developed an high-detailed 3D numerical model

Acute exacerbation of idiopathic pulmonary fibrosis: Lessons learned from acute respiratory distress syndrome?

Idiopathic pulmonary fibrosis (IPF) is a fibrotic lung disease characterized by progressive loss of lung function and poor prognosis. The so-called acute exacerbation of IPF (AE-IPF) may lead to severe hypoxemia requiring mechanical ventilation in the intensive care unit (ICU). AE-IPF shares several pathophysiological features with acute respiratory distress syndrome (ARDS), a very severe condition commonly treated in this setting. A review of the literature has been conducted to underline similarities and differences in the management of patients with AE-IPF and ARDS. During AE-IPF, diffuse alveolar damage and massive loss of aeration occurs, similar to what is observed in patients with ARDS. Differently from ARDS, no studies have yet concluded on the optimal ventilatory strategy and management in AE-IPF patients admitted to the ICU. Notwithstanding, a protective ventilation strategy with low tidal volume and low driving pressure could be recommended similarly to ARDS. The beneficial effect of high levels of positive end-expiratory pressure and prone positioning has still to be elucidated in AE-IPF patients, as well as the precise role of other types of respiratory assistance (e.g., extracorporeal membrane oxygenation) or innovative therapies (e.g., polymyxin-B direct hemoperfusion). The use of systemic drugs such as steroids or immunosuppressive agents in AE-IPF is controversial and potentially associated with an increased risk of serious adverse reactions. Common pathophysiological abnormalities and similar clinical needs suggest translating to AE-IPF the lessons learned from the management of ARDS patients. Studies focused on specific therapeutic strategies during AE-IPF are warranted

Different Methods to Improve the Monitoring of Noninvasive Respiratory Support of Patients with Severe Pneumonia / ARDS Due to COVID-19: An Update.

The last guidelines for the hospital care of patients affected by coronavirus disease-2019 (COVID-19)-related acute respiratory failure have moved towards a widely accepted use of noninvasive respiratory support (NIRS) as opposed to early intubation at the pandemic onset. The establishment of severe COVID-19 pneumonia goes through different pathophysiological phases that partially resemble typical acute respiratory distress syndrome (ARDS) and have been categorized into different clinicalradiological phenotypes. These can variably benefit on the application of external positive end-expiratory pressure (PEEP) during noninvasive mechanical ventilation, mainly due to variable levels of lung recruit ability and lung compliance during different phases of the disease. A growing body of evidence suggests that intense respiratory effort producing excessive negative pleural pressure swings (Ppl) plays a critical role in the onset and progression of lung and diaphragm damage in patients treated with noninvasive respiratory support. Routine respiratory monitoring is mandatory to avoid the nasty continuation of NIRS in patients who are at higher risk for respiratory deterioration and could benefit from early initiation of invasive mechanical ventilation instead. Here we propose different monitoring methods both in the clinical and experimental settings adapted for this purpose, despite further research is required to allow their extensive application in clinical practice. We reviewed the needs and available tools for a clinical-physiological monitoring that aims at optimizing the ventilatory management of patients affected by acute respiratory distress syndrome due to severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection

Ventilatory support and mechanical properties of the fibrotic lung acting as a "squishy ball"

Protective ventilation is the cornerstone of treatment of patients with the acute respiratory distress syndrome (ARDS); however, no studies have yet established the best ventilatory strategy to adopt when patients with acute exacerbation of interstitial lung disease (AE-ILD) are admitted to the intensive care unit. Due to the severe impairment of the respiratory mechanics, the fibrotic lung is at high risk of developing ventilator-induced lung injury, regardless of the lung fibrosis etiology. The purpose of this review is to analyze the effects of mechanical ventilation in AE-ILD and to increase the knowledge on the characteristics of fibrotic lung during artificial ventilation, introducing the concept of "squishy ball lung". The role of positive end-expiratory pressure is discussed, proposing a "lung resting strategy" as opposed to the "open lung approach". The review also discusses the practical management of AE-ILD patients discussing illustrative clinical cases
