PDF-(BOOS)-Measuring User Engagement (Synthesis Lectures on Information Concepts Retrieval

User engagement refers to the quality of the user experience that emphasizes the positive aspects of interacting with an online application and in particular the desire to use that application longer and repeatedly User engagement is a key concept in the design of online applications whether for desktop tablet or mobile motivated by the observation that successful applications are not just used but are engaged with Users invest time attention and emotion in their use of technology and seek to satisfy pragmatic and hedonic needs Measurement is critical for evaluating whether online applications are able to successfully engage users and may inform the design of and use of applications User engagement is a multifaceted complex phenomenon this gives rise to a number of potential measurement approaches Common ways to evaluate user engagement include using selfreport measures eg questionnaires observational methods eg facial expression analysis speech analysis neurophysiological signal processing methods eg respiratory and cardiovascular accelerations and decelerations muscle spasms and web analytics eg number of site visits click depth These methods represent various tradeoffs in terms of the setting laboratory versus in the wild object of measurement user behaviour affect or cognition and scale of data collected For instance smallscale user studies are deep and rich but limited in terms of generalizability whereas largescale web analytic studies are powerful but negate users motivation and context The focus of this book is how user engagement is currently being measured and various considerations for its measurement Our goal is to leave readers with an appreciation of the various ways in which to measure user engagement and their associated strengths and weaknesses We emphasize the multifaceted nature of user engagement and the unique contextual constraints that come to bear upon attempts to measure engagement in different settings and across different user groups and web domains At the same time this book advocates for the development of good measures and good measurement practices that will advance the study of user engagement and improve our understanding of this construct which has become so vital in our wired worldTable of Contents Preface Acknowledgments Introduction and Scope Approaches Based on SelfReport Methods Approaches Based on Physiological Measurements Approaches Based on Web Analytics Beyond Desktop Single Site and Single Task Enhancing the Rigor of User Engagement Methods and Measures Conclusions and Future Research Directions Bibliography Authors Biographies Index.

The reader is taken on a journey that Blomberg and Darrah have been on for the better part of a decade from their respective positions helping to establish a services research group within a large global enterprise and an applied anthropology master\'s program at a Silicon Valley university. They delve into the world of services to understand both how services are being conceptualized today and the possible benefits that might result from taking an anthropological view on services and their design. The authors argue that the anthropological gaze can be useful precisely because it combines attention to details of everyday life with consideration of the larger milieu in which those details make sense. Furthermore it asks us to reflect upon and assess our own perspectives on that which we hope to understand and change. Central to their exploration is the question of how to conceptualize and engage with the world of services given their heterogeneity the increasing global importance of the service economy and the possibilities introduced for an engaged scholarship on service design. While discourse on services and service design can imply something distinctively new the authors point to parallels with what is known about how humans have engaged with each other and the material world over millennia. Establishing the ubiquity of services as a starting point the authors go on to consider the limits of design when the boundaries and connections between what can be designed and what can only be performed are complex and deeply mediated. In this regard the authors outline a practice approach to designing that acknowledges that designing involves participating in a social context that design and use occur in concert that people populate a world that has been largely built by and with others and that formal models of services are impoverished representations of human performance. An Anthropology of Services draws attention to the conceptual and methodological messiness of service worlds while providing the reader with strategies for intervening in these worlds for human betterment as complex and challenging as that may be. Table of Contents Preface / Acknowledgments / Getting Started / From Services to Service Worlds / The Human Condition / Service Concepts / Design and its Limits / Service Design / An anthropology of Services / References / Author Biographies This book explores the design process for user experience and engagement which expands the traditional concept of usability and utility in design to include aesthetics fun and excitement. User experience has evolved as a new area of Human Computer Interaction research motivated by non-work oriented applications such as games education and emerging interactive Web 2.0. The chapter starts by examining the phenomena of user engagement and experience and setting them in the perspective of cognitive psychology in particular motivation emotion and mood. The perspective of aesthetics is expanded towards interaction and engagement to propose design treatments metaphors and interactive techniques which can promote user interest excitement and satisfying experiences. This is followed by reviewing the design process and design treatments which can promote aesthetic perception and engaging interaction. The final part of the chapter provides design guidelines and principles drawn from the interaction and graphical design literature which are cross-referenced to issues in the design process. Examples of designs and design treatments are given to illustrate principles and advice accompanied by critical reflection.
