abstract = {As technological innovations continue to shape our social interactions, the Metaverse introduces im mersive experiences that reflect real-life practices, accessible by users through their avatars. However, these interactions also bring forth potential negative aspects, including discrimination and cyberbullying. While current automatic detection systems exist, educating users on appropriate behaviour remains crucial. Leveraging recent advancements in Artificial Intelligence, the paper focuses on creating virtual AI-controlled moral agents within the Metaverse to guide users in dealing with moral dilemmas. The research aims to understand how such agents impact users’ perceptions and behaviours in ethically challenging virtual environments.},

abstract = {Pseudonymisation is a data protection technique often used to protect the privacy of individuals when their personal data are being used for research purposes. Not only is it a key ingredient of the General Data Protection Regulation (GDPR) that requires organisations to ensure that the personal data they process is handled in a secure manner, but it is particularly important in assisting medical research given that often relies on sensitive personal data, since it reduces the risk that medical data could be misused or mishandled. For managing their medical data, it is important to ensure that such data are protected against unauthorised access, and can be reutilised in an anonymous fashion, while still authorised personnel is able to identify the study participant that some data belong to (e.g., for personalised interventions, technical alerts, technical support). In addition, the re-identification of a study participant is a pre-requisite for exercising their rights under the GDPR, since it assists organisations in meeting GDPR requirements (such as the right to access, rectify and portability of data). We argue that the application of pseudonymisation is particularly effective when considered during the early stages (Privacy by Design) of digital services implementation, as well as when defining the complementary to these organizational procedures. Aim of this paper is to present the way in which the pseudonymisation mechanism of the SMART BEAR H2020 project supports the triptych of research activities conducted within the context of an observational medical study, legal obligations arising from the regulatory framework for the protection of personal data, and reutilisation of data for research purposes. Evidence-based security and privacy assessments will be conducted on two different H2020 projects to evaluate such privacy practice.},

abstract = {An increasing number of innovative technologies are fostering augmented collaborative systems, thus setting the milestones of future collaboration paradigms. By merging real and virtual elements, mixed reality technologies lead to an augmented perception of the working environment and, consequently, an enriched experience of collaborative task execution. However, at the same time, such technologies can also impede proper communication and understanding among the entities working in concert to reach a common goal. Wearing head-mounted displays and simultaneously managing two different interactions - human-human and human-machine can lead to misunderstandings with co-workers. This also can hinder awareness, a fundamental requirement for the effective execution of collaborative tasks. As a consequence, cognitive load can increase with a negative impact on task performance. This paper analyses the main elements of a collaborative practice. Specifically, our aim is to identify crucial factors that must be considered for designing an effective interface for a collaborative mixed reality system. Then, we discuss some solutions to ensure that technology can act as an aid, rather than an impediment, to the accomplishment of collaborative tasks.},

Assuming that such devices could one day replace smartphones for accessing information, creating interfaces safeguarding face-to-face communication is challenging. This work presents the design of an interface that adapts the information visualisation to the presence of a possible interlocutor while allowing a high level of user control. The aim was to define an interface for wearable devices adaptive to interactions coming from the surrounding environment and expressly thought for application domains in which it will be necessary to continuously monitor information. For instance, those applications that require monitoring patient data in medical applications or the progress of a production process in an industrial environment. We focused on human-to-human communication, minimising the use of mid-air interaction to hide the synthetic information that might interrupt the conversation flow. Two different visualisation modalities allowing the coexistence of real and virtual worlds are proposed and evaluated in a preliminary study with six participants who showed a generalised appreciation for the solution which maximises the display of information requiring less user intervention.},

Relying on the Social Practice theory, this work proposes an architecture for the design and development of a virtual agent able to understand social practices in the Metaverse and act by respecting the social norms that the circumstances entail. The agent is equipped with modules for recognizing elements of the scene, knowledge and rules about a set of social practices. The scene information is exploited by a reasoning module that allows the agent to evaluate the current social practice, socially interpret the events, and activate the most appropriate behaviors. The paper describes the proposed architecture, its implementation, and the realization of an experimental virtual scenario.},

The exploration and manipulation of this type of data through see-through augmented reality devices still represents a challenging task. The development of specific interaction strategies capable to mitigating the current limitations of augmented reality devices is essential. In this context, our contribution has been to design possible solutions to address some of these challenges allowing a dynamic interaction with situated information. Following the visual "information-seeking mantra" proposed by Shneiderman and introducing some "superpowers" for the users, in this work we present different strategies aimed at obtaining an overview and filtering, and acquiring details of a collection of situated data.},

abstract = {The main drawback of a detailed representation of visual content, whatever is its origin, is that significant features are very high dimensional. To keep the problem tractable while preserving the semantic content, a dimensionality reduction of the data is needed. We propose the Random Projection techniques to reduce the dimensionality. Even though this technique is sub-optimal with respect to Singular Value Decomposition its much lower computational cost make it more suitable for this problem and in particular when computational resources are limited such as in mobile terminals. In this paper we present the use of a “conceptual” space, automatically induced from data, to perform automatic image annotation. Images are represented by visual features based on color and texture and arranged as histograms of visual terms and bigrams to partially preserve the spatial information [1]. Using a set of annotated images as training data, the matrix of visual features is built and dimensionality reduction is performed using the Random Projection algorithm. A new unannotated image is then projected into the dimensionally reduced space and the labels of the closest training images are assigned to the unannotated image itself. Experiments on large real collection of images showed that the approach, despite of its low computational cost, is very effective.},

However, to promote visitor enjoyment and to enhance the learning process in relation to the cultural heritage, it is fundamental to propose the cultural data to the visitor in an appropriate way through interfaces that help to focus the visitor's attention on the work of art in question. With this aim, new graphical user interfaces should be designed, following a diegetic approach and so providing a more natural and immersive environment to the user. Inspired by the gaming industry, in which the diegetic transformation of graphical user interfaces has already been introduced, in this paper, we will analyze the opportunities offered by the diegetic approach and will evaluate its relevance to the cultural domain. We will highlight the issues related to the applicability of diegetic user interfaces to an immersive virtual exhibition by discussing the different types of cultural data that can be proposed to a visitor and how that should be fictionally integrated into the scene.},

Indeed, extracting clues from a question to generate a query for the information retrieval engine as well as determining the likelihood that a candidate answer is correct are two very thorny tasks. To face these issues, the paper presents a Question Answering pipeline for Italian and based on a corpus of documents pertaining a closed domain. In particular, this pipeline exhibits functionalities for: (i) analyzing natural language questions in Italian by using lexical features; (ii) handling both factoid and description answer types and, depending on them, filtering contextual stop words from questions; (iii) scoring and selecting candidate answers with respect to their type in order to determine the best one.

Using the compositional properties of the WEs we defined a methodology to aggregate the information coming from each word to obtain a vector corresponding to the abstracts of each PubMed article. Through this paradigm it is possible to capture the semantic content of the papers and, consequently, to evaluate and rank the similarity among them. The preliminary results with the proposed approach are obtained analysing a subset of the whole the PubMed collection. The results correctness has been verified by human domain experts, showing that the methodology is promising.},

Due to erroneous or unsupervised physiotherapy, nearly 50% of surgeries fail. Researchers have tried to leverage advances in wearable sensors and motion tracking to build affordable, automated, and customizable rehabilitation systems that help both therapists and patients during physiotherapy sessions. In this paper, we present a patient-centered cardiac surgery rehabilitation system (CSRS) for the personalization of the patient's physiotherapy for the early post-operative period. The system has been designed to interconnect different acquisition sensors and to be distributed on different stations in order to be able to continuously monitor the patient's vital signs and evaluate her/his cognitive and motor abilities in real time.},

abstract = {Modern computing and virtual environment technologies can immerse users into highly realistic computer-generated environments, in which visible and invisible, hypothetical and imaginary objects can be merged into a single, coherent world. These aspects make it natural to apply them to explore areas of cultural interest: a virtual tourist can immerse into places that are inaccessible because only existent in ancient ages, or still existing but closed for repairs, or simply too distant to be reached. An entire city centre can now be reproduced in 4D, with time as the fourth dimension, representing and amplifying centuries of history in a single, virtual space. From a technical and technological perspective, things are evolving fast. Virtual Reality (VR) headsets and development platforms are now cheaper and efficient. High-end solutions such as Oculus Rift, HTC Vive and Sony PlayStation VR, will be all available within the year. For a fully mobile VR experience, Samsung Gear VR and Google Cardboard, in which a smartphone is used it both as the visual and processing unit, are now available too. As a result, after decades of niche products and applications, VR solutions are entering into the mainstream, and opening new scenarios. Let us consider the case of “Splash”, a new-born community: people can capture the space around them with a 360-degree video and then share it to other users that, by using a VR helmet or even a cardboard, can immerse into these distant realities. Experiences, both real and virtual, can now be shared by letting the users to live them with their own point of view. However, the more the presence - the sensation of being there - of the user grows, the more the interactivity becomes challenging. Humans learn and perceive following an interactive process, and this is especially true for the understanding, analysis and interpretation of the cultural patrimony. The immersion into a digital, real or mixed world will require novel technologies and methods to interact with and, somewhat, “feel” such environments. How to navigate within the spatio-temporal continuum, make questions, switch between the different realities of the cultural information? These are only some of the aspects that are now opening methodological discussions and research questions},

We have faced the problem of canonical manipulation which includes, besides the selection, the positioning and rotation. Two different approaches are described allowing respectively a direct or constrained manipulation of the virtual object. Our aim is to evaluate the perceived usability of the two proposed manipulation techniques in the specific configuration and for this reason qualitative data have been gathered using the System Usability Scale questionnaire. The results show a different level of difficulty perceived by the testers between the two canonical manipulation techniques and a general preference for techniques that prove to be less tiring.},

For most of these domains, the large amount of information displayable on top of the reality, directly in the user's field of view, represents an important challenge for designers. In this paper we present a view management technique for placing touristic/cultural information, in the form of points of interest (POIs), in an AR system that works in the absence of a priori knowledge of the real environment. The user-driven view management technique, designed as a remote service, improves representation and displacement of the digital information each time the user manifests an interest in a particular area of the real space. The proposed approach includes a layout algorithm, which exploits the user's local position and her/his point of view direction, to correctly set the POI height in the user's view avoiding overlapping and cluttering, together with an adaptive rendering method, using information about the brightness of the area, that computes the visual appearance parameters of each virtual POI in order to improve its readability over the background.},

The experimental results indicate that, despite the users appreciating the possibility of controlling the travel direction with both head and arrows, not all the directions are considered useful in the same way. However, direct control of the velocity proves to affect positively the navigation experience in all the considered scenarios.},

The excessive blurring provided by the DoG affects the detection of the double and triple junctions that sometimes appear broken while the corners appear rounded. Such a loss in detail is due to the second order approximation of the finite difference (FD) operator adopted to discretize the DoG detector. In this work an improvement of the Canny algorithm is proposed for images having thin edges, computing the edge detector as a convolution of a fourth order accurate FD with the smoothed Gaussian image. The modified wave number analysis of the FD formulation is adopted to motivate the improvement in the edge resolution gained by the fourth order FD discretization. Quantitative comparisons performed with a second order FD discretization of the edge detector adopting both synthetic and benchmark images highlight an improvement in edge localization and in junction detection.},

abstract = {In this paper, an interactive virtual reality (VR) system, realized with the aim of improving the dissemination and presentation of cultural artefacts, is presented. By using off-the-shelf devices, the system provides the users with an interface where a computer generated representation of a cultural artefact can be manipulated in a touch less way. The proposed system could be a useful instrument complementary to a visit to an actual exhibition without requiring any structural intervention, and allowing the user to become an active actor, able to enjoy different prospectives and all the details of the artefact. The paper describes the hardware and software system components, and details the interface specifically designed to obtain a simple and immediate exploration of a cultural heritage artefact. Furthermore, the paper provides the results of a preliminary evaluation of the usability of the interface which revealed up a significant difference between younger and older adult users.},

abstract = {During the last few years, we have been witnessing a widespread adoption of touchless technologies in the context of surgical procedures. Touchless interfaces are advantageous in that they can preserve sterility around the patient, allowing surgeons to visualize medical images without having to physically touch any control or to rely on a proxy. Such interfaces have been tailored to interact with 2D medical images but not with 3D reconstructions of anatomical data, since such an interaction requires at least three degrees of freedom. In this paper, we discuss the results of a user study in which a mouse-based interface has been compared with two Kinect-based touchless interfaces which allow users to interact with 3D data with up to nine degrees of freedom. The experimental results show that there is a significant relation between the number of degrees of freedom simultaneously controlled by the user and the number of degrees of freedom required to perform, in a touchless way, an accurate manipulation task.},

abstract = {Human motion analysis is an increasingly important active research domain with various applications in surveillance, human-machine interaction and human posture analysis. The recent developments in depth sensor technology, especially with the release of the Kinect device, have attracted significant attention to the question of how to take advantage of this technology in order to achieve accurate motion tracking and action detection in marker-less approaches. In this paper, we review the benefits and limitations deriving from the adoption of structured light-based depth sensors in human motion analysis applications. Surveying the relevant literature, we have identified in calibration, interference and bias correction the challenges to tackle for an effective adoption of multi-Kinect systems to improve the visual analysis of human movement.},

abstract = {This paper presents a view-independent hand pose recognition system, which allows the recognition of a limited set of predefined postures from single, low resolution depth images in real time on standard hardware in unconstrained environments. The system consists of three modules: hand segmentation and pose compensation, feature extraction and processing, and hand pose recognition. We use principal component analysis to estimate the hand orientation in space and Flusser moment invariants as image features for visual recognition. The implementation details, classification accuracy and performance measures of the recognition system are reported and discussed. The experimental results show that the system can recognize the pose of two hands at full frame rate with an average total latency lower than 5 ms.},

This paper presents a framework aimed at facilitating the development of natural, touchless user interfaces. The proposed framework, which is based on the publish-subscribe paradigm, allows product and interaction designers to rapidly prototype and test their system by building upon a set of standard modules. The framework also provides the building blocks to extend the basic set of modules, easing code reuse.},
