Offers solutions and best practices to respond to recurrent problems and contemporary challenges in the field Since the publication of the first edition of Environmental Impact Assessment in 2003, both the practice and theory of impact assessment have changed substantially. Not only has the field been subject to a great deal of new regulations and guidelines, it has also evolved tremendously, with a greater emphasis on strategic environmental, sustainability, and human health impact assessments. Moreover, there is a greater call for impact assessments from a global perspective. This Second Edition, now titled Impact Assessment to reflect its broader scope and the breadth of these many changes, offers students and practitioners a current guide to today's impact assessment practice. Impact Assessment begins with an introduction and then a chapter reviewing conventional approaches to the field. Next, the book is organized around recurrent problems and contemporary challenges in impact assessment process design and management, enabling readers to quickly find the material they need to solve tough problems, including: How to make impact assessments more influential, rigorous, rational, substantive, practical, democratic, collaborative, ethical, and adaptive How each problem and challenge-reducing process would operate at the regulatory and applied levels How each problem can be approached for different impact assessment types-sustainability assessment, strategic environmental assessment, project-level EIA, social impact assessment, ecological impact assessment, and health impact assessment How to link and combine impact assessment processes to operate in situations with multiple overlapping problems, challenges, and impact assessment types How to connect and combine impact assessment processes Each chapter first addresses the topic with current theory and then demonstrates how that theory is applied, presenting requirements, guidelines, and best practices. Summaries at the end of each chapter provide a handy tool for structuring the design and evaluation of impact assessment processes and documents. Readers will find analyses and new case studies that address such issues as multi-jurisdictional impact assessment, climate change, cumulative effects assessment, follow-up, capacity building, interpreting significance, and the siting of major industrial and waste facilities. Reflecting current theory and standards of practice, Impact Assessment is appropriate for both students and practitioners in the field, enabling them to confidently respond to a myriad of new challenges in the field.

The human perceptual system can be tricked into believing that one is moving, when in fact, one is not. These self-motion illusions (vection) can be exploited to convincingly simulate self-motion without the need for costly and cumbersome motion platforms. Traditionally, vection has been elicited by moving visual stimuli on custom optokinetic drums or virtual reality (VR) setups. Surprisingly, little is known about contributions of cross-modal effects on vection in contemporary, interactive VR applications. Two studies investigated the effect of active versus passive locomotion and small, actively versus passively generated physical motion cues on optic flow based vection. Twenty four participants used a joystick or gaming chair to navigate on curved (experiment 1, training) or a combination of curved and straight trajectories (experiment 2, main study) presented in an immersive, 3D VR system. The gaming chair allowed for 10 centimeter forward/backward and left/right swivel motions of the seat. Participants experienced four conditions: 1) just watching the scene (passive, no motion cueing), 2) motion cues applied to the participant's seat (passive, motion cueing), 3) joystick locomotion (active, no motion cueing) and 4) participants using the gaming chair for locomotion (active, motion cueing). Overall, participants took 16% longer to experience vection for active compared to passive locomotion. Small, physical motion cues increased vection intensity by 22%. Trajectory curvature most consistently affected vection. Participants experienced vection 34% more intense, 20% earlier and 9% more likely during narrow turns compared to straight paths. Participants experienced vection up to 18% earlier in experiment 2 over experiment 1 possibly due to training effects. It seems that actively controlling locomotion may have distracted participants from the motion stimulus or the task of reporting vection. It became evident that smoothness, precision and ease-of-use of the interface were possible factors that affected vection. In conclusion, vection can be enhanced by using simple motion paradigms and adding curved trajectories to the simulation at minimal cost and effort. For interactive applications, prudent selection of interaction paradigms and ample training is advised.

This book presents a survey of past and recent developments on human walking in virtual environments with an emphasis on human self-motion perception, the multisensory nature of experiences of walking, conceptual design approaches, current technologies, and applications. The use of Virtual Reality and movement simulation systems is becoming increasingly popular and more accessible to a wide variety of research fields and applications. While, in the past, simulation technologies have focused on developing realistic, interactive visual environments, it is becoming increasingly obvious that our everyday interactions are highly multisensory. Therefore, investigators are beginning to understand the critical importance of developing and validating locomotor interfaces that can allow for realistic, natural behaviours. The book aims to present an overview of what is currently understood about human perception and performance when moving in virtual environments and to situate it relative to the broader scientific and engineering literature on human locomotion and locomotion interfaces. The contents include scientific background and recent empirical findings related to biomechanics, self-motion perception, and physical interactions. The book also discusses conceptual approaches to multimodal sensing, display systems, and interaction for walking in real and virtual environments. Finally, it will present current and emerging applications in areas such as gait and posture rehabilitation, gaming, sports, and architectural design.

Volume I, entitled “Augmentation of Brain Functions: Brain-Machine Interfaces”, is a collection of articles on neuroprosthetic technologies that utilize brain-machine interfaces (BMIs). BMIs strive to augment the brain by linking neural activity, recorded invasively or noninvasively, to external devices, such as arm prostheses, exoskeletons that enable bipedal walking, means of communication and technologies that augment attention. In addition to many practical applications, BMIs provide useful research tools for basic science. Several articles cover challenges and controversies in this rapidly developing field, such as ways to improve information transfer rate. BMIs can be applied to the awake state of the brain and to the sleep state, as well. BMIs can augment action planning and decision making. Importantly, BMI operations evoke brain plasticity, which can have long-lasting effects. Advanced neural decoding algorithms that utilize optimal feedback controllers are key to the BMI performance. BMI approach can be combined with the other augmentation methods; such systems are called hybrid BMIs. Overall, it appears that BMI will lead to many powerful and practical brain-augmenting technologies in the future.
