Wired for Speech: How Voice Activates and Advances the Human-Computer Relationship

by Scott Brave Clifford Nass

Interfaces that talk and listen are populating computers, cars, call centers, and even home appliances and toys, but voice interfaces invariably frustrate rather than help. In Wired for Speech, Clifford Nass and Scott Brave reveal how interactive voice technologies can readily and effectively tap into the automatic responses all speech -- whether from human or machine -- evokes. Wired for Speech demonstrates that people are "voice-activated": we respond to voice technologies as we respond to actual people and behave as we would in any social situation. By leveraging this powerful finding, voice interfaces can truly emerge as the next frontier for efficient, user-friendly technology. Wired for Speech presents new theories and experiments and applies them to critical issues concerning how people interact with technology-based voices. It considers how people respond to a female voice in e-commerce (does stereotyping matter?), how a car's voice can promote safer driving (are "happy" cars better cars?), whether synthetic voices have personality and emotion (is sounding like a person always good?), whether an automated call center should apologize when it cannot understand a spoken request ("To Err is Interface; To Blame, Complex"), and much more. Nass and Brave's deep understanding of both social science and design, drawn from ten years of research at Nass's Stanford laboratory, produces results that often challenge conventional wisdom and common design practices. These insights will help designers and marketers build better interfaces, scientists construct better theories, and everyone gain better understandings of the future of the machines that speak with us.

Wired into Nature: The Telegraph and the North American Frontier (History of Communication)

by James Schwoch

The completion of the Transcontinental Telegraph in 1861 completed telegraphy's mile-by-mile trek across the West. In addition to linking the coasts, the telegraph represented an extraordinary American effort in many fields of endeavor to know, act upon, and control a continent. Merging new research with bold reinterpretation, James Schwoch details the unexplored dimensions of the frontier telegraph and its impact. The westward spread of telegraphy entailed encounters with environments that challenged Americans to acquire knowledge of natural history, climate, and a host of other fields. Telegraph codes and ciphers, meanwhile, became important political, military, and economic secrets. Schwoch shows how the government's use of commercial networks drove a relationship between the two sectors that served increasingly expansionist aims. He also reveals the telegraph's role in securing high ground and encouraging surveillance. Both became vital aspects of the American effort to contain, and conquer, the West's indigenous peoples--and part of a historical arc of concerns about privacy, data gathering, and surveillance that remains pertinent today. Entertaining and enlightening, Wired into Nature explores an unknown history of the West.

by Brian J.W. Regli

The revolution of wireless communications has only just begun to transform the telecommunications industry worldwide. This book offers insight into the possible options for corporate strategists and government policymakers as they look to harness the expansion of wireless communications to meet the goals of sustainable telecommunications development. Using a multidisciplinary approach which combines policy research, legal analysis, business economics, and models of sustainability from the environmental sciences, the book compares the development of wireless communications in four countries: the United States, the United Kingdom, Russia, and Brazil. The comparative analysis points to common themes and opportunities, including: * breaking down the barriers between wireless and wireline access by changing the regulatory design which constrains service providers; * targeting the development potential of wireless access through the utilization of new technologies and service models; and * using wireless access as the basis for full facilities-based competition in both developing and developed world markets. No other book today offers this broad a context for a discussion of wireless communications and its potential impact on the evolution of the telecommunications industry.

Wireless Communications for Power Substations: RF Characterization and Modeling (Wireless Networks)

by Basile L. Agba Fabien Sacuto Minh Au Fabrice Labeau François Gagnon

This book consists of the identification, characterization, and modeling of electromagnetic interferences in substations for the deployment of wireless sensor networks. The authors present in chapter 3 the measurement setup to record sequences of impulsive noise samples in the ISM band of interest. The setup can measure substation impulsive noise, in wide band, with enough samples per time window and enough precision to allow a statistical study of the noise. During the measurement campaign, the authors recorded around 120 noise sequences in different substations and for four ranges of equipment voltage, which are 25 kV, 230 kV, 315 kV and 735 kV. A characterization process is proposed, by which physical characteristics of partial discharge can be measured in terms of first- and second-order statistics. From the measurement campaign, the authors infer the characteristics of substation impulsive noise as a function of the substation equipment voltage, and can provide representative parameters for the four voltage ranges and for several existing impulsive noise models.The authors investigate in chapters 4 and 5 the modeling of electromagnetic interferences caused by partial discharge sources. First, the authors propose a complete and coherent approach model that links physical characteristics of high-voltage installations to the induced radio-interference spectra of partial discharge sources. The goodness-of-fit of the proposed physical model has been measured based on some interesting statistical metrics. This allows one to assess the effectiveness of the authors' approach in terms of first- and second-order statistics. Chapter 6 proposes a model based on statistical approach. Indeed, substation impulsive noise is composed of correlated impulses, which would require models with memory in order to replicate a similar correlation. Among different models, we have configured a Partitioned Markov Chain (PMC) with 19 states (one state for the background noise and 18 states for the impulse); this Markov-Gaussian model is able to generate impulsive noise with correlated impulse samples. The correlation is observable on the impulse duration and the power spectrum of the impulses. Our PMC model provides characteristics that are more similar to the characteristics of substation impulsive noise in comparison with other models, in terms of time and frequency response, as well as Probability Density Functions (PDF). Although PMC represents reliably substation impulsive noise, the model remains complex in terms of parameter estimation due to a large number of Markov states, which can be an obstacle for future wireless system design. In order to simplify the model, the authors decrease the number of states to 7 by assigning one state to the background noise and 6 states to the impulse and we call this model PMC-6. PMC-6 can generate realistic impulses and can be easily implemented in a receiver in order to mitigate substation impulsive noise. Representative parameters are provided in order to replicate substation impulsive noise for different voltage ranges (25-735 kV). Chapter 7, a generalized radio-noise model for substations is proposed, in which there are many discharges sources that are randomly distributed over space and time according to the Poisson field of interferers approach. This allows for the identification of some interesting statistical properties of moments, cumulants and probability distributions. These can, in turn, be utilized in signal processing algorithms for rapid partial discharge's identification, localization, and impulsive noise mitigation techniques in wireless communications in substations.The primary audience for this book is the electrical and power engineering industry, electricity providers and companies who are interested in substation automation systems using wireless communication technologies for smart grid applications. Researchers, engineers and students studying and working in wireless communication will also want to buy this book as a reference.

Wireless Communications Security: Solutions for the Internet of Things

Wireless Communications under Hostile Jamming: Security and Efficiency

by Tongtong Li Tianlong Song Yuan Liang

This monograph is intended for the designers and would-be designers of secure and efficient wireless communication systems under intentional interference. Along with the widespread of wireless devices, especially reconfigurable software defined radios, jamming has become a serious threat to civilian communications. In this book, going beyond traditional communication system design that mainly focuses on accurate information transmission under benign environments, we aim to enhance the physical layer security of communication systems by integrating modern cryptographic techniques into transceiver design, so as to achieve secure high-speed transmission under hostile interference with high reliability and efficiency. We revisit existing jamming patterns, and introduce new jamming patterns. We analyze the weaknesses of existing anti-jamming techniques. We present innovative and feasible anti-jamming techniques, which can strengthen the inherent security of the 3G, 4G and the upcoming 5G systems with minimal and inexpensive changes to the existing CDMA, frequency hopping and OFDM schemes. We also provide benchmarks for system performance evaluation under various jamming scenarios through capacity analysis. This book includes design principles, in-depth theoretical analysis and practical design examples, and will be of interest to academic researchers as well as professionals in industry.

Wireless Independent Living for a Greying Population (River Publishers Series In Standardisation Ser.)

by Lara Srivastava

It is widely known today that not only are the aged ageing, or the old getting older, but they are also increasing in number the world over. At the same time, proper care and support for our aged is increasingly at risk. Without some form of support, the quantitative extension of life cannot be matched by a qualitative one. This may mean that the opportunity provided by a longer life is squandered, and life itself, of course, is nothing if not opportunity. Societies find that self-sufficiency and independence not only contribute to individual well-being, but are also economically desirable due to the resultant increase in productivity.The challenges of daily living for a growing population of the aged form the basis of the independent living platform, the AGE@HOME platform, which is described in this book. The platform combines both existing and emerging technologies suitable for the home. Its use and application is considered in the wider context of Web 2.0, the internet of things, and other elements of the burgeoning digital world. It is time that a holistic and multi-disciplinary approach to this constantly enlarging area of human existence is taken.This book is written for researchers and designers of wireless tools, analog and digital circuits as well as academics who are active in the various fields of Human Sciences.Foreword"This book appears at the right moment when several developments have made age and its consequences an important element of human existence. It makes for informative reading, being based on considerations related to independence for the aged and the application of emerging technologies to enhance this independence......."From the foreword by:Houlin ZhaoDeputy Secretary-General of theInternational Telecommunication Union
