Book Description
Adaptive 3D Sound Systems focuses on creating multiple virtual sound sources in 3D reverberant spaces using adaptive filters. Adaptive algorithms are introduced and explained, including the multiple-error filtered-x algorithm and the adjoint LMS algorithm. The book covers the physical, psychoacoustical, and signal processing aspects of adaptive and non-adaptive 3D sound systems. Included is an introduction to spatial hearing, sound localization and reverberation, frequency selectivity of the human auditory system, the state of the art in HRTF-based 3D sound systems, binaural synthesis, and loudspeaker displays. The adaptive approach to HRTF-based 3D sound systems is examined in detail for the general case of creating multiple virtual sound sources at the ears of multiple listeners in a reverberant 3D space. The derived solution can be applied to other applications, such as cross-talk cancellation, loudspeakers and room equalization, concert hall simulation, and active sound control. Several solutions for the problem of moving listeners are introduced. Strategies for enlarging the zones of equalization around the listeners' ears, correct loudspeakers positioning, and using multiresolution filters are proposed. Fast multiresolution spectral analysis using non-uniform sampling is developed for implementation of multiresolution filters. The well-focused topics, along with implementation details for adaptive algorithms, make Adaptive 3D Sound Systems suitable for multimedia applications programmers, advanced level students, and researchers in audio and signal processing.

Book Description
Users of signal processing systems are never satis?ed with the system they currently use. They are constantly asking for higher quality, faster perf- mance, more comfort and lower prices. Researchers and developers should be appreciative for this attitude. It justi?es their constant e?ort for improved systems. Better knowledge about biological and physical interrelations c- ing along with more powerful technologies are their engines on the endless road to perfect systems. This book is an impressive image of this process. After “Acoustic Echo 1 and Noise Control” published in 2004 many new results lead to “Topics in 2 Acoustic Echo and Noise Control” edited in 2006 . Today – in 2008 – even morenew?ndingsandsystemscouldbecollectedinthisbook.Comparingthe contributions in both edited volumes progress in knowledge and technology becomesclearlyvisible:Blindmethodsandmultiinputsystemsreplace“h- ble” low complexity systems. The functionality of new systems is less and less limited by the processing power available under economic constraints. The editors have to thank all the authors for their contributions. They cooperated readily in our e?ort to unify the layout of the chapters, the ter- nology, and the symbols used. It was a pleasure to work with all of them. Furthermore, it is the editors concern to thank Christoph Baumann and the Springer Publishing Company for the encouragement and help in publi- ing this book.

Book Description
This book on Robust Speech Recognition and Understanding brings together many different aspects of the current research on automatic speech recognition and language understanding. The first four chapters address the task of voice activity detection which is considered an important issue for all speech recognition systems. The next chapters give several extensions to state-of-the-art HMM methods. Furthermore, a number of chapters particularly address the task of robust ASR under noisy conditions. Two chapters on the automatic recognition of a speaker's emotional state highlight the importance of natural speech understanding and interpretation in voice-driven systems. The last chapters of the book address the application of conversational systems on robots, as well as the autonomous acquisition of vocalization skills.

Book Description
The Complete, Up-To-Date Guide to Building Great 3D User Interfaces for Any Application 3D interaction is suddenly everywhere. But simply using 3D input or displays isn’t enough: 3D interfaces must be carefully designed for optimal user experience. 3D User Interfaces: Theory and Practice, Second Edition is today’s most comprehensive primary reference to building state-of-the-art 3D user interfaces and interactions. Five pioneering researchers and practitioners cover the full spectrum of emerging applications, techniques, and best practices. The authors combine theoretical foundations, analysis of leading devices, and empirically validated design guidelines. This edition adds two new chapters on human factors and general human-computer interaction—indispensable foundational knowledge for building any 3D user interface. It also demonstrates advanced concepts at work through two running case studies: a first-person VR game and a mobile augmented reality application. Coverage Includes 3D user interfaces: evolution, elements, and roadmaps Key applications: virtual and augmented reality (VR, AR), mobile/wearable devices What 3D UI designers should know about human sensory systems and cognition ergonomics How proven human-computer interaction techniques apply to 3D UIs 3D UI output hardware for visual, auditory, and haptic/ tactile systems Obtaining 3D position, orientation, and motion data for users in physical space 3D object selection and manipulation Navigation and wayfinding techniques for moving through virtual and physical spaces Changing application state with system control techniques, issuing commands, and enabling other forms of user input Strategies for choosing, developing, and evaluating 3D user interfaces Utilizing 2D, “magic,” “natural,” multimodal, and two-handed interaction The future of 3D user interfaces: open research problems and emerging technologies

Book Description
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.

Book Description
This book first introduces the background of spatial audio reproduction, with different types of audio content and for different types of playback systems. A literature study on the classical and emerging Primary Ambient Extraction (PAE) techniques is presented. The emerging techniques aim to improve the extraction performance and also enhance the robustness of PAE approaches in dealing with more complex signals encountered in practice. The in-depth theoretical study helps readers to understand the rationales behind these approaches. Extensive objective and subjective experiments validate the feasibility of applying PAE in spatial audio reproduction systems. These experimental results, together with some representative audio examples and MATLAB codes of the key algorithms, illustrate clearly the differences among various approaches and also help readers gain insights on selecting different approaches for different applications.

Book Description
Building on ideas from cognitive metaphor theory, Making Sense of Recordings offers a new perspective on record production, music perception, and the aesthetics of recorded sound. It shows how the language about sound is intimately connected to sense-making - both as a reflection of our internal cognitive capacities and as a component of our extended cognitive system. In doing so, the book provides the foundation for a broader understanding of the history of listening, discourses of sound quality, and artistic practices in the age of recorded music. The book will be of interest to anyone who asks how recorded music sounds and why it sounds as it does, and it will be a valuable resource for musicology students and researchers interested in the analysis of sound and the history of listening and record production. Additionally, sound engineers and laptop musicians will benefit from the book's exploration of the connection between embodied experiences and our cognitively processed experiences of recorded sound. The tools provided will be useful to these and other musicians who wish to intuitively interact with recorded or synthesized sound in a manner that more closely resembles the way they think and that makes sense of what they do.
