The Mathematical Table of the Palazzina Cinese in Palermo. Animation and Virtual Reality Techniques for an Edutainment Project
2023
The Palazzina Cinese of Palermo was built on a project by Venanzio Marvuglia in 1799 on behalf of Ferdinand IV of Borbone, when the royal family, fleeing from Naples following the establishment of the Parthenopean Republic, moved to Sicily. The building, known as “Chinese” due to its style, is full of particular architectural and decorative solutions. An element of particular interest is theMathematical Table, designed to avoid any contact between the living room and the kitchen below, isolating it from smells and servants. Thanks to a complex system of winches and pulleys, in fact, the dishes could be served by letting the central portion of the table and small circular areas fall into the…
Innovative techniques for survey and communication of cultural heritage
2008
This paper deals with the survey and communications of Cultural Heritage through the development of innovative methodologies. The case of study is the polychrome wooden ceiling in the “Magna” Hall of “Palazzo Steri”. The “Steri”, built in the XIVth century by the noble family Chiaromonte, is at the present the headquarter of the Rector’s Office of Palermo University. A 3D model of the wooden ceiling has initially been carried out with laser-scanning and digital photogrammetric techniques; successively a multimodal interactive guide has been realized. The guide is integrated to the 3D model, so that visitors can navigate the virtual representation of the ancient wood ceiling and achieve, int…
Digital experience for the enhancement of cultural heritage. VR and AR models of the Valentin im Viertel farmhouse.
2019
Il saggio affronta lo studio del maso Valentim im Viertel attraverso la realizzazione del modello digitale utilizzato come strumento per la conoscenza dell’architettura della tradizione del Sud Tirolo. La metodologia adottata si basa sull’acquisizione dei dati rielaborati attraverso modelli VR e AR per la valorizzazione del patrimonio. This study deals with development of the farmhouse Valentim im Viertel digital model used as a tool for the knowledge of the South Tyrol traditional architecture. The methodological approach shows the acquisition of data and the use of VR and AR models for the enhancement of the cultural heritage.
Decision Making and Cognitive Behavioral Flexibility in a OCD Sample: a Study in a Virtual Environment
2015
Neuropsychological disorders are common in Obsessive-Compulsive Disorder (OCD) patients. Executive functions, verbal fluency and verbal memory, shifting attention from one aspect of stimuli to others, mental flexibility, engaging in executive planning and decision making, are the most involved cognitive domains. We focus on two aspects of neuropsychological function: decision making and cognitive behavioral flexibility, assessed through a virtual version of the Multiple Errand Test (V-MET), developed using the NeuroVR software.Thirty OCD patients were compared with thirty matched control subjects. The results showed the presence of difficulties in OCD patients with tasks where the goal is n…
The New Era of Business Digitization through the Implementation of 5G Technology in Romania
2021
The main objective of the present research is to identify the advantages and benefits that the use and implementation of 5G technology has on the development and evolution of the Romanian business environment. The study is based on a theoretical documentation regarding existing information in the field and a descriptive analysis of the evolution of the technology in Romania and worldwide. The research method chosen is a survey based on an opinion poll (questionnaire) to find out the availability of economic entities regarding the implementation of 5G technologies, the foreseen expectations and those realized by the business environment regarding the effects of 5G technologies on the economi…
Deep and Meaningful E-Learning with Social Virtual Reality Environments in Higher Education: A Systematic Literature Review
2021
Deep and meaningful learning (DML) in distant education should be an essential outcome of quality education. In this literature review, we focus on e-learning effectiveness along with the factors and conditions leading to DML when using social virtual reality environments (SVREs) in distance mode higher education (HE). Hence, a systematic literature review was conducted summarizing the findings from thirty-three empirical studies in HE between 2004 (appearance of VR) and 2019 (before coronavirus appearance). We searched for the cognitive, social, and affective aspects of DML in a research framework and studied their weight in SVREs. The findings suggest that the use of SVREs can provide aut…
Stakeholder Strategy and Design Alignment Framework for Design Science Research – A Study in the Context of VR-Aided Marketing and Sales
2020
This study introduces a framework to align various perceptions and objectives that different stakeholders have at the beginning of a Design Science Research (DSR) process and consolidate them into stakeholders’ strategies and theory-ingrained design artifacts. We coin this framework as Stakeholder Strategy and Design Alignment (SSDA). As an application area, we concentrate on a Virtual Reality (VR) application designed for marketing and sales purposes. The empirical testing of the framework shows that the marketing and sales potential of the application are, indeed, perceived very differently among three stakeholder groups: company representatives, developers and customers. In addition to t…
Collaborative Virtual Reality for Laparoscopic Liver Surgery Training
2019
Virtual reality (VR) has been used in many medical training systems for surgical procedures. However, the current systems are limited due to inadequate interactions, restricted possibilities of patient data visualization, and collaboration. We propose a collaborative VR system for laparoscopic liver surgical planning and simulation. Medical image data is used for model visualization and manipulation. Additionally, laparoscopic surgical joysticks are used to provide an opportunity for a camera assistant to cooperate with an experienced surgeon in VR. Continuous clinical feedback led us to optimize the visualization, synchronization, and interactions of the system. Laparoscopic surgeons were …
A collaborative virtual reality environment for liver surgery planning
2021
Abstract Surgical planning software is a key component in the treatment of tumor diseases. However, desktop-based systems provide only limited visualization and interaction opportunities. Moreover, collaborative planning among members of a surgical team is only possible to a limited extent. In this work, a collaborative virtual reality (VR) environment to assist liver surgeons in tumor surgery planning is presented. Our aim is to improve virtual resection planning between surgeons in a remote or co-located environment. The system allows surgeons to define and adjust virtual resections on patient-specific organ 3D surfaces and 2D image slices. Changes on both modalities are synchronized, whi…
Dynamic interface for machine vision systems
2002
Iconic programming intends to provide expressive tools to implement, to debug, and to execute programs. For this purpose, visual languages need pictorial constructs and metaphors to guide the design of algorithms in interactive fashion. In the paper a new class of dynamic visual interfaces, named DIVA (Dynamic Interface for Visual Applications), is introduced, its properties are described, and an application to visual compilers in a multi-processors system dedicated to image analysis is given. Moreover, a formal definition of dynamic icon (DI) is also given.
