User Acceptance of Mobile Notifications
by Tilo WestermannThis book presents an alternative approach to studying smartphone-app user notifications. It starts with insights into user acceptance of mobile notifications in order to provide tools to support users in managing these. It extends previous research by investigating factors that influence users' perception of notifications and proposes tools addressing the shortcomings of current systems. It presents a technical framework and testbed as an approach for evaluating the usage of mobile applications and notifications, and then discusses a series of studies based on this framework that investigate factors influencing users' perceptions of mobile notifications. Lastly, a set of design guidelines for the usage of mobile notifications is derived that can be employed to support users in handling notifications on smartphones.
User-Centered Agile Method
by Dominique Deuff Mathilde CosquerAgile development methods began to emerge around 20 years ago. However, it was not until the early 2000s that they began to be widely used in industry. This growth was often due to the advent of Internet services requiring faster cycles of development in order to heighten the rate at which an ever-greater number of functionalities were made available. In parallel, user-centered design (UCD) methods were also becoming more and more widely used: hence, user-centered design and agile methods were bound to cross paths, at least in the telecoms industry! During this period, in the field of telecommunications, the explosion in the number of connected terminals, Web applications, new use environments (particularly in a domestic setting), etc., meant it was crucial to gain a fuller understanding of users’ requirements and better evaluate the relevance and acceptance of services’ attempts to cater for these requirements. Thus the user-centered agile method, as proposed in this book, aims to mutually integrate two existing methods: user-centered design – as used by ergonomists – and the agile Scrum method – as used by developers. The user testing method is also covered. Analyzing work on this subject spanning the past 10 years, the authors also provide an assessment of the feedback on the user-centered agile method. The method described in this book has been based on all these sources. It is a framework relying on the logic introduced by Scrum, i.e. a framework based on project management. The method proposed is seen as an extension of Scrum which is “centered on humans” because of the integration of user-centered design and user-testing. Therefore the description of the user-centered agile method is based on the basics of the agile Scrum method and uses its terminology and elements. As well as descriptive elements of the user-centered agile method, practical examples of how to implement it are also provided. Contents 1. Introduction. 2. Intrioduction to the Methods Employed. 3. Sources for this Work. 4. Description of The User-Centered Agile Method. 5. Case Studies. About the Authors Dominique Deuff worked at the National Institute of Informatics in Japan for 2½ years before coming back to France in June 2006 and joining Orange Labs France Telecom as a developer in a Scrum team. In 2008, she graduated with a Master’s degree in ergonomics and has since then been applying her new skills to various projects at Orange Labs Lannion. Mathilde Cosquer joined Orange Labs as an ergonomist after completing her PhD on the question of transparency of technical devices from the user’s point of view. She has taken part in the design and evaluation of numerous innovating services, but over the past four years, she has been more particularly involved in projects of interpersonal communication services.
User-centered Requirements: The Scenario-based Engineering Process
by Karen L. McGraw Karan HarbisonDeveloping today's complex systems requires more than just good software engineering solutions. Many are faced with complex systems projects, incomplete or inaccurate requirements, canceled projects, or cost overruns, and have their systems' users in revolt and demanding more. Others want to build user-centric systems, but fear managing the process. This book describes an approach that brings the engineering process together with human performance engineering and business process reengineering. The result is a manageable user-centered process for gathering, analyzing, and evaluating requirements that can vastly improve the success rate in the development of medium-to-large size systems and applications. Unlike some texts that are primarily conceptual, this volume provides guidelines, "how-to" information, and examples, enabling the reader to quickly apply the process and techniques to accomplish the following goals: * define high quality requirements, * enhance productive client involvement, * help clients maintain competitiveness, * ensure client buy-in and support throughout the process, * reduce missing functionality and corrections, and * improve user satisfaction with systems. This volume clearly details the role of user-centered requirements and knowledge acquisition within Scenario-Based Engineering Process (SEP) and identifies SEP products and artifacts. It assists project personnel in planning and managing effective requirements activities, including managing risks, avoiding common problems with requirements elicitation, organizing project participants and tools, and managing the logistics. Guidelines are provided for the following: selecting the right individual and group techniques to elicit scenarios and requirements from users; subject matter experts, or other shareholders; and ensuring engineers or analysts have the necessary skills.
User-Centered Technology: A Rhetorical Theory for Computers and Other Mundane Artifacts
by Robert R. JohnsonPresents a theoretical model for examining technology through a user perspective.

User Experience Design in the Era of Automated Driving (Studies in Computational Intelligence #980)
by Andreas Riener Myounghoon Jeon Ignacio AlvarezThis book is dedicated to user experience design for automated driving to address humane aspects of automated driving, e.g., workload, safety, trust, ethics, and acceptance. Automated driving has experienced a major development boost in recent years. However, most of the research and implementation has been technology-driven, rather than human-centered. The levels of automated driving have been poorly defined and inconsistently used. A variety of application scenarios and restrictions has been ambiguous. Also, it deals with human factors, design practices and methods, as well as applications, such as multimodal infotainment, virtual reality, augmented reality, and interactions in and outside users. This book aims at 1) providing engineers, designers, and practitioners with a broad overview of the state-of-the-art user experience research in automated driving to speed-up the implementation of automated vehicles and 2) helping researchers and students benefit from various perspectives and approaches to generate new research ideas and conduct more integrated research.

User Requirements for Wireless (River Publishers Series In Communications Ser.)
by Lene Tolstrup Sørensen Knud Erik SkoubyIn most IT system development processes, the identification or elicitation of user requirements is recognized as a key building block. In practice, the identification of user needs and wants is a challenge and inadequate or faulty identifications in this step of an IT system development can cause huge problems with the final product. The elicitation of user requirements as such changes according to age groups;, to gender,; to cultural settings,; and into time; and experience in the use of the system/software. User requirements, therefore, cannot be used between projects, IT systems, and different software. That makes the elicitation of user requirements an inherent part of any software development project and a resourceful activity as well. This book provides insights to the process of identifying user requirements and to different types by describing varying case studies in which technologies or software has been developed. A variety of user requirements are provided illustrating the effect of changing the targeted user group with respect to age,; to the context and the different technologies or software as well as to the difference in viewpoint on ways of involving users in the elicitation process. Cases and user requirement elements discussed in the book include: • User requirements elicitation processes for children, construction workers, and farmers• User requirements for personalized services of a broadcast company• Variations in user involvement• Practical elements of user involvement and requirements elicitation• Usable security requirements for design of privacy.

User Unfriendly: Consumer Struggles with Personal Technologies, from Clocks and Sewing Machines to Cars and Computers
by Joseph J. CornWe’ve all been there. Seduced by the sleek designs and smart capabilities of the newest gadgets, we end up stumped by their complicated set-up instructions and exasperating error messages. In this fascinating history, Joseph J. Corn maps two centuries of consumer frustration and struggle with personal technologies.Aggravation with the new machines people adopt and live with is as old as the industrial revolution. Clocks, sewing machines, cameras, lawn mowers, bicycles, electric lights, cars, and computers: all can empower and exhilarate, but they can also exact a form of servitude. Adopters puzzle over which type and model to buy and then how to operate the device, diagnose its troubles, and meet its insatiable appetite for accessories, replacement parts, or upgrades. It intrigues Corn that we put up with the frustrations our technology thrusts upon us, battling with the unfamiliar and climbing the steep learning curves. It is this ongoing struggle, more than the uses to which we ultimately put our machines, that animates this thought-provoking study.Having extensively researched owner’s manuals, computer user-group newsletters, and how-to literature, Corn brings a fresh, consumer-oriented approach to the history of technology. User Unfriendly will be valuable to historians of technology, students of American culture, and anyone interested in our modern dependence on machines and gadgets.
