    Recommendation systems are specialized in offering suggestions about specific items of different types (e.g., books, movies, restaurants, and hotels) that could be interesting for the user. They have attracted considerable research attention due to their benefits and also their commercial interest. Particularly, in recent years, the concept of context-aware recommendation system has appeared to emphasize the importance of considering the context of the situations in which the user is involved in order to provide more accurate recommendations. The detection of the context requires the use of sensors of different types, which measure different context variables. Despite the relevant role played by sensors in the development of context-aware recommendation systems, sensors and recommendation approaches are two fields usually studied independently. In this paper, we provide a survey on the use of sensors for recommendation systems. Our contribution can be seen from a double perspective. On the one hand, we overview existing techniques used to detect context factors that could be relevant for recommendation. On the other hand, we illustrate the interest of sensors by considering different recommendation use cases and scenarios

    Seven HCI Grand Challenges

    Get PDF
    This article aims to investigate the Grand Challenges which arise in the current and emerging landscape of rapid technological evolution towards more intelligent interactive technologies, coupled with increased and widened societal needs, as well as individual and collective expectations that HCI, as a discipline, is called upon to address. A perspective oriented to humane and social values is adopted, formulating the challenges in terms of the impact of emerging intelligent interactive technologies on human life both at the individual and societal levels. Seven Grand Challenges are identified and presented in this article: Human-Technology Symbiosis; Human-Environment Interactions; Ethics, Privacy and Security; Well-being, Health and Eudaimonia; Accessibility and Universal Access; Learning and Creativity; and Social Organization and Democracy. Although not exhaustive, they summarize the views and research priorities of an international interdisciplinary group of experts, reflecting different scientific perspectives, methodological approaches and application domains. Each identified Grand Challenge is analyzed in terms of: concept and problem definition; main research issues involved and state of the art; and associated emerging requirements

    Enhanced Living Environments

    This open access book was prepared as a Final Publication of the COST Action IC1303 “Algorithms, Architectures and Platforms for Enhanced Living Environments (AAPELE)”. The concept of Enhanced Living Environments (ELE) refers to the area of Ambient Assisted Living (AAL) that is more related with Information and Communication Technologies (ICT). Effective ELE solutions require appropriate ICT algorithms, architectures, platforms, and systems, having in view the advance of science and technology in this area and the development of new and innovative solutions that can provide improvements in the quality of life for people in their homes and can reduce the financial burden on the budgets of the healthcare providers. The aim of this book is to become a state-of-the-art reference, discussing progress made, as well as prompting future directions on theories, practices, standards, and strategies related to the ELE area. The book contains 12 chapters and can serve as a valuable reference for undergraduate students, post-graduate students, educators, faculty members, researchers, engineers, medical doctors, healthcare organizations, insurance companies, and research strategists working in this area

    Wearable Computing for Health and Fitness: Exploring the Relationship between Data and Human Behaviour

    Get PDF
    Health and fitness wearable technology has recently advanced, making it easier for an individual to monitor their behaviours. Previously self generated data interacts with the user to motivate positive behaviour change, but issues arise when relating this to long term mention of wearable devices. Previous studies within this area are discussed. We also consider a new approach where data is used to support instead of motivate, through monitoring and logging to encourage reflection. Based on issues highlighted, we then make recommendations on the direction in which future work could be most beneficial

    Emotion-oriented interventions for environment and the facilitation of pro-environmental behavior

    Dissertação para obtenção do Grau de Doutor em Ambiente, pela Universidade Nova de Lisboa, Faculdade de Ciências e TecnologiaThis research aimed at studying the facilitating pro-environmental behavior problem by approaching new pro-environmental interventions. The following elements make this study particularly relevant: a) the actual debate concerning the impact of scientific and technological innovations and b) the consideration of new emotional research findings, which stress that emotion is an essential part of information processing. However, the role of emotions is still largely absent from most pro-environmental studies. This situation highlights the importance of conceiving personal and professional initiatives aimed at encouraging reflection and supporting proenvironmental behaviors research while focusing on emotional issues. The study involved an interpretative approach of a qualitative nature, organized in two complementary phases. The first phase evaluated the possible impact of the purposed research. It involved different collaborations and the first experimental research study was implemented as a proof-of-concept approach. In addition, this phase research advanced a new model of proenvironmental behavior and a design framework. The second phase of the study, motivated by the results of the first phase, led to advancing emotion-oriented interventions scenarios and also planning and implementing their evaluation. This initiative showed two technological opportunities to consider for future developments: Affective images rewarding systems using digital material and sensorial feedback tools using non-digital material. The planned qualitative research included questionnaires, semi-structured interviews, panels, observation and the analysis of documents. The results of this study have several implications. Among the most relevant are: a) the potential of combined research methods in investigating individuals conceptions and perceptions about environmental behavior; b) the importance of discussions about new pro-environmental interventions for facilitating pro-environmental behavior; c) the importance of multi-disciplinary research approaches for advancing new technological options; and d) the relevance of considering an emotion-oriented approach.Fundação para a Ciência e a Tecnologia (FCT/MCTES)- (SFRH/BD/21408/2005
