    The 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

    The need for impulsivity & smoothness: improving HCI by qualitatively measuring new high-level human motion features

    No full text
    The aim of this paper is to develop algorithms to measure motion features by investigating concepts which are commonly used to describe movement characteristics in both research studies and everyday life: impulsivity and smoothness. We also aim to implement such definitions in our developing environment EyesWeb and finally test if they can effectively measure impulsivity and smoothness in the same way these characteristics are perceived by human users

    Using movement sonification to alter body perception and promote physical activity in physically inactive people

    Mención Internacional en el título de doctorWorldwide, one out of four adults are not physically active enough. Supporting people to be physically active through technology remains thus an important challenge in the field of Human-Computer Interaction (HCI). Some technologies have tried to tackle this challenge of increasing physical activity (PA) by using sensing devices for monitoring the amount and quality of PA and providing motivational feedback on it. However, such technologies provide very limited support to physically inactive users: while users are aware of their physical inactivity level, they are frequently incapable of acting on these problems by themselves. Among the reasons for it are negative perceptions about one’s body (e.g., feelings of body tiredness or weakness in self-esteem) which may act as psychological barriers to PA. This research project aims to address this limitation by employing an approach that, through movement sonification (i.e., real-time auditory feedback on body movement), exploits bottom-up multisensory mechanisms related to BPs to ultimately support PA. This thesis presents the design, development, and evaluation of SoniShoes and SoniBand, two wearable technological devices with a gesture-sound palette that allows for a range of body movement sonifications aimed to alter BPs. These prototypes aim at changing BPs, and in turn emotional state and movement behavior, to address psychological barriers related to the perception of one’s body, and ultimately impact positively on people’s adherence to PA. First, this work proposes to organize knowledge through a taxonomy of the barriers to PA related to body perception (BP), which follows a process of four steps to inform the design of the movement-sound palette: (1) Identification, (2) Extraction and clustering of attributes, (3) Definition of instructions or considerations, and (4) Strategies. The first two steps allowed the identification and grouping of barriers to PA that are related to BPs, with inputs from a literature review, a survey, and a focus group with HCI experts. The third and fourth steps allowed defining the body features and dimensions to act upon, to finally propose movement sonification strategies that have the potential to tackle the barriers. Second, several movement-sound mappings, based on metaphors, are presented. Movements were selected from exercises included in guidelines for becoming more physically active (e.g., walking). The mappings of these movements into sounds were implemented in SoniShoes and SoniBand prototypes. They were evaluated through an iterative process, starting with an exploratory study that tested for the first time the potential of the proposed mappings to change BPs. In this first study, participants were asked to think aloud about their experiences using the first prototype of SoniShoes (from MagicShoes project), by describing their body sensations and sound characteristics during the exercise. Results suggested the potential of movement sonification to alter BP through movement sonification and informed the design of the subsequent studies and prototypes. This exploratory study was followed by quantitative and qualitative studies aimed to understand how to design movement sonifications and wearable devices integrating them to facilitate PA by tackling barriers related to BP. The quantitative studies were controlled laboratory studies, in which different versions of SoniShoes and SoniBand prototypes were evaluated, and which results led to further iterations of the prototypes. The results of these quantitative evaluations revealed movement-sound mappings that can lead to changes in feelings about the body (e.g., feeling lighter or less tired), feelings about the movement (e.g., having more movement control over the movement), and emotional feelings (e.g., having more comfort, motivation to complete the exercise, or feeling happier) during PA. Results also showed effects of sound on movement behavior, such as effects in movement deceleration/acceleration and stance time, and proprioceptive awareness. Furthermore, two qualitative studies were carried out, which involved using the SoniBand prototype for several days and in two different contexts of use, laboratory and home. The aim of these studies was two-fold. First, elucidating the effects that particular metaphorical sonifications’ qualities and characteristics have on people’s perception of their own body and their PA. Second, understanding how the observed effects may be specific to physically inactive (vs. active) populations. The results revealed specific connections between properties of the movement sonifications (e.g., gradual or frequency changes) on the one hand, and particular body feelings (e.g., feeling strong) and aspects of PA (e.g., repetitions) on the other hand, but effects seem to vary according to the PA-level of the populations. Finally, the findings, contributions, and principles for the design of movement sonifications and wearable technology to promote PA through acting upon BP are discussed, finishing by considering implications for potential interventions and applications supporting PA, as well as opportunities opened for future research.En todo el mundo, uno de cada cuatro adultos no es lo suficientemente activo físicamente. Por ello, ayudar a las personas a ser físicamente activas a través de la tecnología sigue siendo un reto importante en el campo de “Human-Computer Interaction” (HCI). Algunas tecnologías han tratado de abordar el reto de aumentar la actividad física (PA) mediante el uso de dispositivos de detección para controlar la cantidad y la calidad de la PA y proporcionar retroalimentación motivacional al respecto. Sin embargo, estas tecnologías proporcionan una ayuda muy limitada a los usuarios físicamente inactivos: aunque los usuarios son conscientes de su nivel de inactividad física, a menudo son incapaces de actuar por sí mismos sobre estos problemas. Entre las razones están las percepciones negativas sobre el propio cuerpo (por ejemplo, la sensación de cansancio corporal o el no sentirse capaces) que pueden actuar como barreras psicológicas para la PA. Este proyecto de investigación pretende abordar esta limitación empleando un enfoque que, a través de la sonificación del movimiento (es decir, la retroalimentación auditiva en tiempo real sobre el movimiento del cuerpo), explota los mecanismos “bottom-up” multisensoriales relacionados con las percepciones del cuerpo (BPs) para apoyar la PA. Esta tesis presenta el diseño, el desarrollo y la evaluación de “SoniShoes” y “SoniBand”, dos dispositivos tecnológicos vestibles con una paleta de gestos y sonidos que permiten una serie de sonificaciones del movimiento corporal destinadas a modificar las BPs. Estos prototipos tienen como objetivo cambiar las BPs, y a su vez el estado emocional y el comportamiento de movimiento, para abordar las barreras psicológicas relacionadas con la BP, y en última instancia impactar positivamente en la adherencia de las personas a la PA. En primer lugar, este trabajo propone organizar el conocimiento a través de una taxonomía de las barreras a la PA relacionadas con la BP, que sigue un proceso de cuatro pasos para informar el diseño de la paleta de movimiento-sonido: (1) Identificación, (2) Extracción y agrupación de atributos, (3) Definición de instrucciones o consideraciones, y (4) Estrategias. Los dos primeros pasos permitieron identificar y agrupar las barreras a la PA relacionadas con los BP, con aportaciones de una revisión bibliográfica, una encuesta y un grupo de discusión con expertos en HCI. El tercero y cuarto paso permitió definir las características y dimensiones corporales sobre las que actuar, para finalmente proponer estrategias de sonificación del movimiento que tienen el potencial de abordar las barreras. En segundo lugar, se presentan varios mapeos de movimiento-sonido, basados en metáforas. Los movimientos se seleccionaron a partir de ejercicios incluidos en las guías para ser más activos físicamente (por ejemplo, caminar). Los mapeos de estos movimientos en sonidos se implementaron en los prototipos “SoniShoes” y “SoniBand”. Se evaluaron a través de un proceso iterativo, comenzando con un estudio exploratorio que probó por primera vez el potencial de los mapeos propuestos para cambiar los BP. En este primer estudio, se pidió a los participantes que pensaran en voz alta sobre sus experiencias utilizando el primer prototipo de “SoniShoes” (llamado “MagicShoes”), describiendo sus sensaciones corporales y las características del sonido durante el ejercicio. Los resultados mostraron el potencial de la sonificación del movimiento para alterar la BP a través de la sonificación del movimiento e informaron el diseño de los estudios y prototipos posteriores. A este estudio exploratorio le siguieron estudios cuantitativos y cualitativos destinados a comprender cómo diseñar sonificaciones del movimiento y dispositivos vestibles que las integren para facilitar la PA abordando las barreras relacionadas con la BP. Los estudios cuantitativos fueron estudios de laboratorio controlados, en los que se evaluaron diferentes versiones de los prototipos “SoniShoes” y “SoniBand”, y cuyos resultados condujeron a nuevas iteraciones de los prototipos. Los resultados de estas evaluaciones cuantitativas mostraron que existen mapeos de movimiento-sonido que pueden provocar cambios en las sensaciones sobre el cuerpo (por ejemplo, sentirse más ligero o menos cansado), en las sensaciones sobre el movimiento (por ejemplo, tener más control sobre el movimiento) y en las sensaciones emocionales (por ejemplo, tener más comodidad, motivación para completar el ejercicio o sentirse más feliz) durante la PA. Los resultados también mostraron los efectos del sonido en el comportamiento del movimiento, como los efectos en la desaceleración/aceleración del movimiento y el tiempo de postura, y la conciencia propioceptiva. Además, se llevaron a cabo dos estudios cualitativos, en los que se utilizó el prototipo “SoniBand” durante varios días y en dos contextos de uso diferentes, el laboratorio y el hogar. El objetivo de estos estudios era doble. En primer lugar, dilucidar los efectos que determinadas cualidades y características de las sonificaciones con metáforas tienen en la percepción que las personas tienen de su propio cuerpo y de su PA. En segundo lugar, comprender cómo los efectos observados pueden ser específicos de las poblaciones físicamente inactivas (vs. las activas). Los resultados revelaron conexiones específicas entre las propiedades de las sonificaciones de movimiento (por ejemplo, los cambios graduales o de frecuencia) por un lado, y las sensaciones corporales particulares (por ejemplo, sentirse fuerte) y los aspectos de la PA (por ejemplo, las repeticiones) por otro lado, pero los efectos parecen variar según el nivel de PA de las poblaciones. Por último, se discuten los hallazgos, las contribuciones y las guías de diseño de sonificación de movimiento y tecnología vestible para promover la PA a través de la actuación sobre la BP, para finalmente considerar las implicaciones para las posibles intervenciones y aplicaciones de apoyo a la PA, así como las oportunidades abiertas para futuras investigaciones.I owe thanks to “MAGIC SHOES” (PSI2016-79004-R and BES-2017-080471) and “CROSS-COLAB” (PGC2018-101884-B-I00) projects that funded my research.

    OVERVIEW (taken from the CALL FOR PAPERS) Academics and practitioners with an interest in the concept of (tele)presence are invited to submit their work for presentation at PRESENCE 2005 at University College London in London, England, September 21-23, 2005. The eighth in a series of highly successful international workshops, PRESENCE 2005 will provide an open discussion forum to share ideas regarding concepts and theories, measurement techniques, technology, and applications related to presence, the psychological state or subjective perception in which a person fails to accurately and completely acknowledge the role of technology in an experience, including the sense of 'being there' experienced by users of advanced media such as virtual reality. The concept of presence in virtual environments has been around for at least 15 years, and the earlier idea of telepresence at least since Minsky's seminal paper in 1980. Recently there has been a burst of funded research activity in this area for the first time with the European FET Presence Research initiative. What do we really know about presence and its determinants? How can presence be successfully delivered with today's technology? This conference invites papers that are based on empirical results from studies of presence and related issues and/or which contribute to the technology for the delivery of presence. Papers that make substantial advances in theoretical understanding of presence are also welcome. The interest is not solely in virtual environments but in mixed reality environments. Submissions will be reviewed more rigorously than in previous conferences. High quality papers are therefore sought which make substantial contributions to the field. Approximately 20 papers will be selected for two successive special issues for the journal Presence: Teleoperators and Virtual Environments. PRESENCE 2005 takes place in London and is hosted by University College London. The conference is organized by ISPR, the International Society for Presence Research and is supported by the European Commission's FET Presence Research Initiative through the Presencia and IST OMNIPRES projects and by University College London

    Environmental surveillance on construction sites requires environmental information that is concise, to-the-point, timely and usable. However, physical surveillance andtraditional environmental monitoring (measurement) are challenging, time consuming, labour-intensive and can involve deficiencies and discrepancies. Technology basedsurveillance provides an alternative, but with this kind of surveillance it is often difficult to demonstrate a connection between any pollution detected and a specificsource in some circumstances. Thus, physical environmental surveillance (observation/walk-through inspection) still remains important but some improvementscan be made to it by adopting technology based surveillance. This situation creates an opportunity for deploying an information system which capitalizes on the advantages of the Internet of Things, so that decision makers can obtain an accurate and up-to-date view of their environmental management issues and status.The aim of this research was, therefore, to set out to investigate the potential for a mobile environmental information system as a part of the Internet of Thingstechnologies for environmental surveillance on Malaysian construction sites. Design Science Research (DSR) has been chosen as the philosophical approach and case studyas the research method were adopted for this research in order to achieve its objectives. A literature review on construction environmental management and mobile environmental information management was undertaken, followed by engagement with environmental experts in order to obtain detailed information requirements and toidentify user needs. These details were analysed and brought about the formulation of the system design goals, along with a conceptual model, which concluded in thedevelopment of the functional specification, the system architecture and the prototype development. The prototype system was demonstrated and evaluated interactively byconstruction environmental management teams, both in the UK and Malaysia.The main achievement of the research comprises the analysis of the needs required in a mobile environmental information system, the development of functional specifications and the demonstration and acceptance of the concept by practising construction environmental management teams. The research concludes that the concept of a mobile environmental information system is feasible, realising that it has greatly improving the task performing process as well as enhancing the flow of communication and reporting environmental surveillance activities on construction sites in nearly real time
