This book is a comprehensive and authoritative guide to voice user interface (VUI) design. The VUI is perhaps the most critical factor in the success of any automated speech recognition (ASR) system, determining whether the user experience will be satisfying or frustrating, or even whether the customer will remain one. This book describes a practical methodology for creating an effective VUI design. The methodology is scientifically based on principles in linguistics, psychology, and language technology, and is illustrated here by examples drawn from the authors' work at Nuance Communications, the market leader in ASR development and deployment. The book begins with an overview of VUI design issues and a description of the technology. The authors then introduce the major phases of their methodology. They first show how to specify requirements and make high-level design decisions during the definition phase. They next cover, in great detail, the design phase, with clear explanations and demonstrations of each design principle and its real-world applications. Finally, they examine problems unique to VUI design in system development, testing, and tuning. Key principles are illustrated with a running sample application. A companion Web site provides audio clips for each example: www.VUIDesign.org The cover photograph depicts the first ASR system, Radio Rex: a toy dog who sits in his house until the sound of his name calls him out. Produced in 1911, Rex was among the few commercial successes in earlier days of speech recognition. Voice User Interface Design reveals the design principles and practices that produce commercial success in an era when effective ASRs are not toys but competitive necessities.

From the voice on the phone, to the voice on the computer, to the voice from the toaster, speech user interfaces are coming into the mainstream and are here to stay forever. Soundly anchored in HCI, cognitive psychology, linguistics, and social psychology, this supremely practical book is loaded with examples, how-to advice, and design templates. Drawing widely on decades of research—in lexicography, conversation analysis, computational linguistics, and social psychology—author Randy Allen Harris outlines the principles of how people use language interactively, and illustrates every aspect of design work.In the first part of the book, Harris provides a thorough conceptual basis of language in all its relevant aspects, from speech sounds to conversational principles. The second part takes you patiently through the entire process of designing an interactive speech system: from team building to user profiles, to agent design, scripting, and evaluation. This book provides interaction designers with the knowledge and strategies to craft language-based applications the way users will expect them to behave. *Loaded with examples and practical synopses of the best practice. *An ideal combination of conceptual base, practical illustrations, and "how-to" advice—for design and for the entire design process.*Will bring novice voice designers fully up to speed, and give experienced designers a new understanding of the principles underlying human speech interaction, principles from which to improve voice interaction design.

Here’s what three pioneers in computer graphics and human-computer interaction have to say about this book: “What a tour de force—everything one would want—comprehensive, encyclopedic, and authoritative.” — Jim Foley “At last, a book on this important, emerging area. It will be an indispensable reference for the practitioner, researcher, and student interested in 3D user interfaces.” — Andy van Dam “Finally, the book we need to bridge the dream of 3D graphics with the user-centered reality of interface design. A thoughtful and practical guide for researchers and product developers. Thorough review, great examples.” — Ben Shneiderman As 3D technology becomes available for a wide range of applications, its successful deployment will require well-designed user interfaces (UIs). Specifically, software and hardware developers will need to understand the interaction principles and techniques peculiar to a 3D environment. This understanding, of course, builds on usability experience with 2D UIs. But it also involves new and unique challenges and opportunities. Discussing all relevant aspects of interaction, enhanced by instructive examples and guidelines, 3D User Interfaces comprises a single source for the latest theory and practice of 3D UIs. Many people already have seen 3D UIs in computer-aided design, radiation therapy, surgical simulation, data visualization, and virtual-reality entertainment. The next generation of computer games, mobile devices, and desktop applications also will feature 3D interaction. The authors of this book, each at the forefront of research and development in the young and dynamic field of 3D UIs, show how to produce usable 3D applications that deliver on their enormous promise. Coverage includes: The psychology and human factors of various 3D interaction tasks Different approaches for evaluating 3D UIs Results from empirical studies of 3D interaction techniques Principles for choosing appropriate input and output devices for 3D systems Details and tips on implementing common 3D interaction techniques Guidelines for selecting the most effective interaction techniques for common 3D tasks Case studies of 3D UIs in real-world applications To help you keep pace with this fast-evolving field, the book’s Web site, www.3dui.org, will offer information and links to the latest 3D UI research and applications.

Master the critical knowledge you need to design speech-enabled applications It's not just a far-fetched gizmo straight out of a sci-fi movie anymore. Speech interface technology, which allows a user to communicate with computers via voice instead of a keyboard or a mouse, is quickly becoming a main feature in new software. This straightforward guide provides traditional graphical user-interface designers, developers, usability engineers, and product managers with all the information they need to make a rapid transition in order to stay abreast of this monumental shift in technology. Weinschenk and Barker, two experts in state-of-the-art online communication, discuss the basics of speech interfaces and speech technology, hardware, and software. They clearly explain the interface design principles that are applied to S/GUI and AUI interfaces and describe the latest practices of leading experts. In addition to its in-depth look at speech technologies and the different types of user interfaces, this book: * Provides an overview of the field of human factors and defines the basic concepts of human computer interaction * Discusses the current state of speech technology applications * Explains the laws of human factors that apply to speech interfaces * Contains guidelines and examples for user control, human limitation, model integrity, accommodation, clear dialogue, and aesthetic integrity * Details the best practices in interface design and usability engineering * Explores the special issues involved in interface design for disabled persons Visit the companion web site at www.wiley.com/compbooks/weinschenk/ for a categorized resource list of speech, speech interface, and human-computer interaction books, articles, and links.

User interface design is a challenging, multi-disciplinary activity that requires understanding a wide range of concepts and techniques that are often subjective and even conflicting. Imagine how much it would help if there were a single perspective that you could use to simplify these complex issues down to a small set of objective principles. In UI is Communication, Everett McKay explains how to design intuitive user interfaces by focusing on effective human communication. A user interface is ultimately a conversation between users and technology. Well-designed user interfaces use the language of UI to communicate to users efficiently and naturally. They also recognize that there is an emotional human being at the other end of the interaction, so good user interfaces strive to make an emotional connection. Applying what you learn from UI is Communication will remove much of the mystic, subjectiveness, and complexity from user interface design, and help you make better design decisions with confidence. It’s the perfect introduction to user interface design. Approachable, practical communication-based guide to interaction and visual design that you can immediately apply to projects to make solid design decisions quickly and confidently Includes design makeovers so you can see the concepts in practice with real examples Communication-based design process ties everything from interaction to visual design together
