Multisensory learning in adaptive interactive systems
No full textThe main purpose of my work is to investigate multisensory perceptual learning and sensory integration in the design and development of adaptive user interfaces for educational purposes. To this aim, starting from renewed understanding from neuroscience and cognitive science on multisensory perceptual learning and sensory integration, I developed a theoretical computational model for designing multimodal learning technologies that take into account these results. Main theoretical foundations of my research are multisensory perceptual learning theories and the research on sensory processing and integration, embodied cognition theories, computational models of non-verbal and emotion communication in full-body movement, and human-computer interaction models. Finally, a computational model was applied in two case studies, based on two EU ICT-H2020 Projects, "weDRAW" and "TELMI", on which I worked during the PhD
Exploiting multimodal integration in adaptive interactive systems and game-based learning interfaces
No full textThe main purpose of my work is to investigate multisensory and multimodal integration in the design and development of adaptive systems and interfaces for game-based learning applications in the areas of education and rehabilitation. To this aim, I contributed to the creation of a multimodal dataset of violin performances, integrating motion capture, video, audio, and on-body sensors (accelerometers and EMG), and I worked closely with psychophysicists and educators on the design of paradigms and technologies for multisensory and embodied learning of mathematics in primary school children. Main theoretical foundations of my research are multisensory processing and integration, psychophysics analysis, embodied cognition theories, computational models of non-verbal and emotion communication in full-body movement, and human-computer interaction models for adaptive interfaces and serious-games
Designing a Multisensory Social Serious-Game for Primary School Mathematics Learning
No full textPsychophysical and developmental psychology evidence shows that children have a preferential sensory channel to learn specific concepts, highlighting the need of a multisensory approach to education. Despite such a potential for a positive impact, in education technology research multisensory learning has been often penalised and limited by design choices. In this work, we present the requirements and the design of an implementable prototype of serious-game aimed at teaching children a precise mathematical concept: Angles. The game is based on the interaction between different sensory modalities, in particular movement, vision, and sound
Automatically measuring biomechanical skills of violin performance
No full textThis evaluation study explores how automated movement analysis can be used to catch the biomechanical skills needed for a physically accurate violin performance, maximizing efficiency and minimizing injuries. Starting from a previously recorded multimodal dataset, we compute movement features from motion captured data of five violinists performing three violin exercises: octave shift, string crossing, and a Romantic repertoire piece. Three violin teachers were asked to evaluate audio, video, and both audio and video stimuli of the selected exercises. We correlated their ratings with automatically extracted movement features. Whereas these features are purely visual (i.e., they are computed from motion captured data only), we asked teachers to also evaluate audio because it can be considered as the direct translation of movement skills into another modality. In this way, we can also look at possible relations between evaluation of the audio aspects of the performance and biomechanical skills of violin playing. Results show that the proposed movement features can be partially used to measure the biomechanical skills of the violin players to support learning and mitigate the risk of injuries
Gerontechnology: Definitions and Classification
No full textTechnology is now part of our lives and the current perception by patients and their caregivers, healthcare professionals, managers and policy makers is that a modern view of medicine includes the technologies as essential instruments both in clinical practice, i.e. assessment, management and follow-up of patients and more in general in many healthcare processes as diagnosis, prognosis, treatments, rehabilitation and prevention both at individual and at general population level.
In this chapter we present an overview of the different definitions and classifications of technologies potentially useful for older people including: (i) Information and communication technologies, i.e. tools aimed at informing and communicating, including digital technologies, telehealth programs and the application of artificial intelligence in healthcare; (ii) assistive technologies designed to maintain older people’s independence and increasing safety including ambient and personal sensors and domotic devices; and (iii) human-computer interaction technologies to support treatment and rehabilitation of older people with mobility and cognitive impairments such as robots (humanoid, rehabilitation, service and companion-type robots) but also exergames and virtual reality activities and their clinical and social components
Enhancing children understanding of mathematics with multisensory technology
No full textRecent results from psychophysics and developmental psychology show that children do not integrate and use the same sensory modalities in the same way, but they rather have a preferential sensory channel to learn specific concepts. In schools, however, the visual channel is often the only one exploited for teaching, whereas the other channels are left to a marginal role. The weDRAW project, an ongoing European two-years project, explores the chance to create and evaluate new methodologies to teaching, grounded on multisensory technologies. In particular, the project targets a deeper understanding of arithmetic and geometry. A major novelty of such a new technology is that it is based on the renewed understanding of what communication between senses is and how it occurs during child development, that is, that specific sensory systems have specific roles for learning specific concepts. Neuroscientific prospectives suggest that it is possible to develop new teaching/learning channels, personalized for each student based on the child's sensory skills. This practice work consists of a demo simulating a set-up in a primary school, where children with any level of previous mathematical knowledge can try the technologies themselves. The demo includes full-body activities to "play" and "draw" arithmetical and geometrical concepts, such as playing a fraction using body rhythms and drawing shapes and symmetries
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
