This volume brings together papers by experts in different areas of computer science, who have a common interest in the design and management of visual interfaces. Since cognitive science and metaphor analysis prove useful for understanding the basic mechanisms which allow visual interfaces to be easy to learn and use, these topics are also featured. Other areas focused on are: visual languages, visual database systems, intelligent agents for system interaction, graphical and pictorial communication tools, multimedia environments and specific technological developments.

This book constitutes the thoroughly refereed post-workshop proceedings of the AVI 2016 Workshop on Road Mapping Infrastructures for Advanced Visual Interfaces Supporting Big Data Applications in Virtual Research Environments, AVI-BDA 2016, held in Bari, Italy, in June 2016. The 10 revised full papers in this volume present the elaborated outcome of the initial position papers capturing the results oft the roadmapping discussions in the workshop at which comments of several external reviewers for these full publications were also integrated.

This book constitutes the thoroughly refereed post-workshop proceedings of the AVI 2020 Workshop on Road Mapping Infrastructures for Artificial Intelligence Supporting Advanced Visual Big Data Analysis, AVI-BDA 2020, held in Ischia, Italy, in June 2020, and the Second Italian Workshop on Visualization and Visual Analytics, held in Ischia, Italy, in September 2020. The 14 regular papers in this volume present topics such as big data collection, management and curation; big data analytics; big data interaction and perception; big data insight and effectuation; configuration and management of big data storage and compute infrastructures, services, and tools; advanced visual interaction in big data applications; user empowerment and meta design in big data applications; prediction and automation of big data analysis workflows; as well as data visualization; information visualization; visual analytics; infographics; and design.

This book is primarily a summary of research done over 10 years in multimedia and virtual reality, which fits within a wider interest of exploiting psychological theory to improve the process of designing interactive systems. The subject matter lies firmly within the field of HCI, with some cross-referencing to software engineering. Extending Sutcliffe's views on the design process to more complex interfaces that have evolved in recent years, this book: *introduces the background to multisensory user interfaces and surveys the design issues and previous HCI research in these areas; *explains the basic psychology for design of multisensory user interfaces, including the Interactive Cognitive Subsystems cognitive model; *describes elaborations of Norman's models of action for multimedia and VR, relates these models to the ICS cognitive model, and explains how the models can be applied to predict the design features necessary for successful interaction; *provides a design process from requirements, user and domain analysis, to design of representation in media or virtual worlds and facilities for user interaction therein; *covers usability evaluation for multisensory interfaces by extending existing well-known HCI approaches of heuristic evaluation and observational usability testing; and *presents two special application areas for multisensory interfaces: educational applications and virtual prototyping for design refinement.

Voice user interfaces (VUIs) are becoming all the rage today. But how do you build one that people can actually converse with? Whether you’re designing a mobile app, a toy, or a device such as a home assistant, this practical book guides you through basic VUI design principles, helps you choose the right speech recognition engine, and shows you how to measure your VUI’s performance and improve upon it. Author Cathy Pearl also takes product managers, UX designers, and VUI designers into advanced design topics that will help make your VUI not just functional, but great.Understand key VUI design concepts, including command-and-control and conversational systemsDecide if you should use an avatar or other visual representation with your VUIExplore speech recognition technology and its impact on your designTake your VUI above and beyond the basic exchange of informationLearn practical ways to test your VUI application with usersMonitor your app and learn how to quickly improve performanceGet real-world examples of VUIs for home assistants, smartwatches, and car systems

Ironically, many designers of graphical user interfaces are not always aware of the fundamental design rules and techniques that are applied routinely by other practitioners of communication-oriented visual design -- techniques that can be used to enhance the visual quality of GUIs, data displays, and multimedia documents. This volume focuses on design rules and techniques that are drawn from the rational, functionalist design aesthetic seen in modern graphic design, industrial design, interior design, and architecture -- and applies them to various graphical user interface problems experienced in commercial software development.Describes the basic design principles (the what and why), common errors, and practical step-by-step techniques (the how) in each of six major areas: elegance and simplicity; scale, contrast, and proportion; organization and visual structure; module and program; image and representation; and style. Focuses on techniques that will not only improve the aesthetics of the visual display, but, because they promote visual organization, clarity, and conciseness, will also enhance the usability of the product. Includes a catalog of common errors drawn from existing GUI applications and environments to illustrate practices that should be avoided in developing applications.For anyone responsible for designing, specifying, implementing, documenting, or managing the visual appearance of computer-based information displays.

Understanding Virtual Reality: Interface, Application, and Design, Second Edition arrives at a time when the technologies behind virtual reality have advanced dramatically. The book helps users take advantage of the ways they can identify and prepare for the applications of VR in their field. By approaching VR as a communications medium, the authors have created a resource that will remain relevant even as underlying technologies evolve. Included are a history of VR, systems currently in use, the application of VR, and the many issues that arise in application design and implementation, including hardware requirements, system integration, interaction techniques and usability. - Features substantive, illuminating coverage designed for technical or business readers and the classroom - Examines VR's constituent technologies, drawn from visualization, representation, graphics, human-computer interaction and other fields - Provides (via a companion website) additional case studies, tutorials, instructional materials, and a link to an open-source VR programming system - Includes updated perception material and new sections on game engines, optical tracking, VR visual interface software, and a new glossary with pictures
