Crowdsourcing Cultural Heritage: From 3D Modeling to the Engagement of Young Generations
2016
Monitoring, digitizing and archiving museum artworks represent an important socio-cultural accomplishment and an overcoming in digital preservation today. Cultural heritage is constantly under threat of terrorist attacks and natural disaster. The high costs related to documentation task have prevented a constantly and massive survey activity. The low cost 3D image based acquisition and elaboration techniques of an object, allow to carry out a 3D photorealistic model in a short time. Therefore, a lot of museum adopted these techniques for the artworks archiving. Crowdsourcing activities can significantly speed up survey and elaboration procedures. If, on the one hand, these initiatives can h…
A narratological approach to content selection in audio description: towards a strategy for the description of narratological time
2012
As more and more countries start to provide audio description services for a growing range of products and events, research into this new discipline is growing and diversifying as well. Two questions that seem to be at the heart of much of this research focus on what should be described and how this should be done, in other words on content selection and formulation of the description. The present article looks at the first of these two questions and approaches it from a narratological point of view. After a general discussion of the use of narratology for audio description, the focus will shift to one particular constituent of narrative, namely time. The different temporal aspects will be …
Current communication technologies in language processing
2015
Even the most cutting-edge communication-mediated technology like satellite navigation for orbit positioning, pedestrian movement recognition systems based on inertial sensors, 5G systems, let alone medical devices for coordination of human organs functionality would not be invented without technologies for language processing as an information source between humans and communication systems. Regardless of the way we communicate that is via emails, website short tweets, video conferencing systems, social networking, blogs, instant messaging through websites or mobile applications, or texting only, we use a language that is processed by computer system. Thus, the keynote paper discusses lang…
An fMRI Study to Analyze Neural Correlates of Presence during Virtual Reality Experiences
2013
[EN] In the field of virtual reality (VR), many efforts have been made to analyze presence, the sense of being in the virtual world. However, it is only recently that functional magnetic resonance imaging (fMRI) has been used to study presence during an automatic navigation through a virtual environment. In the present work, our aim was to use fMRI to study the sense of presence during a VR-free navigation task, in comparison with visualization of photographs and videos (automatic navigations through the same environment). The main goal was to analyze the usefulness of fMRI for this purpose, evaluating whether, in this context, the interaction between the subject and the environment is perf…
Whatsapp messenger as a tool for the multidisciplinary management in everyday clinical practice
2017
Introduction & Objectives Communication between doctors is traditionally conducted by written clinical charts. Mobile health is becoming an integral part of modern healthcare system, improving accessibility and quality of medical care. Recent papers suggest that an increasing number of doctors are using in their practice mobile tools to communicate clinical informations (1,2). The aim of our study was to verify the adoption of WhatsApp Messenger in everyday clinical practice to obtain a real-time multidisciplinary collaboration among medical centers located in different areas of the city. Material & Methods In January 2016 a WhatsApp Messenger group was created among 25 specialists:…
Privacy preserving via tree augmented naïve Bayesian classifier in multimedia database
2011
International audience; In this paper, we propose a novel technique for privacy preserving in multimedia databases. Our technique is based on a multimedia co-occurrence matrix and a tree augmented naive Bayesian classifier (TAN) to detect possible data associations making confidential multimedia objects at risk.
Guidance Provided by Teacher and Simulation for Inquiry-Based Learning: a Case Study
2016
Current research indicates that inquiry-based learning should be guided in order to achieve optimal learning outcomes. The need for guidance is even greater when simulations are used because of their high information content and the difficulty of extracting information from them. Previous research on guidance for learning with simulations has concentrated on guidance provided by the simulation. Little research has been done on the role of the teacher in guiding learners with inquiry-based activities using simulations. This descriptive study focuses on guidance provided during small group investigations; pre-service teachers (n = 8) guided third and fifth graders using a particular simulatio…

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.
An Augmented Reality System for Treating Psychological Disorders: Application to Phobia to Cockroaches
2005
Augmented reality has been used in many fields, but it has not been used to treat psychological disorders. Augmented reality presents several advantages respect to: the traditional treatment of psychological disorders and virtual reality treatments. In this paper we present the first augmented reality system for the treatment of phobia to cockroaches. Our system has been developed using ARToolkit software. It has been tested with one patient and the results have been very satisfactory. At first of the exposure session the patient was not able to approach to a real cockroach and after the exposure session using our augmented reality system, the patient was able to approach to a real cockroac…
