Human Walking in Virtual Environments


Book Description

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.




Locomotion and Posture in Older Adults


Book Description

This book is an attempt to advance the discussion and improve our understanding about the effects of aging and movement disorders on motor control during walking and postural tasks. Despite these activities are performed daily, there is a high requirement of motor and neural systems in order to perform both tasks efficiently. Both walking and posture require a complex interaction of musculoskeletal and neural systems. However, the mechanisms used to control these tasks, as well as how they are planned and coordinated, are still a question of discussion among health professionals and researchers. In addition, this discussion is more interesting when the effects of aging are included in the context of locomotion and the postural control. The number of older individuals is 841 million in 2015, which is four times higher than the 202 million that lived in 1950. Aging causes many motor, sensorial and neural deficits, which impair locomotion and postural control in the elderly. The severity of this framework is worsened when the aging goes along with a movement disorder, such as Parkinson disease, Chorea, Dystonia, Huntington disease, etc. Therefore, the aim of this book is to highlight the influence of different aspects on planning, controlling and performing locomotion and posture tasks. In attempting to improve current knowledge in this field, invited authors present and discuss how environmental, sensorial, motor, cognitive and individual aspects influence the planning and performance of locomotor and postural activities. The major thrust of the book is to address the mechanisms involved in controlling and planning motor action in neurological healthy individuals, as well as in those who suffer from movement disorders or face the effects of aging, indicating the aspects that impair locomotion and postural control. In addition, new technologies, tools and interventions designed to manage the effects of aging and movement disorders are presented in the book.




Virtual Reality for Physical and Motor Rehabilitation


Book Description

While virtual reality (VR) has influenced fields as varied as gaming, archaeology and the visual arts, some of its most promising applications come from the health sector. Particularly encouraging are the many uses of VR in supporting the recovery of motor skills following accident or illness. Virtual Reality for Physical and Motor Rehabilitation reviews two decades of progress and anticipates advances to come. It offers current research on the capacity of VR to evaluate, address, and reduce motor skill limitations and the use of VR to support motor and sensorimotor function, from the most basic to the most sophisticated skill levels. Expert scientists and clinicians explain how the brain organizes motor behavior, relate therapeutic objectives to client goals and differentiate among VR platforms in engaging the production of movement and balance. On the practical side, contributors demonstrate that VR complements existing therapies across various conditions such as neurodegenerative diseases, traumatic brain injury and stroke. Included among the topics: Neuroplasticity and virtual reality. Vision and perception in virtual reality. Sensorimotor recalibration in virtual environments. Rehabilitative applications using VR for residual impairments following stroke. VR reveals mechanisms of balance and locomotor impairments. Applications of VR technologies for childhood disabilities. A resource of great immediate and future utility, Virtual Reality for Physical and Motor Rehabilitation distills a dynamic field to aid the work of neuropsychologists, rehabilitation specialists (including physical, speech, vocational and occupational therapists), and neurologists.




The Neural Bases of Multisensory Processes


Book Description

It has become accepted in the neuroscience community that perception and performance are quintessentially multisensory by nature. Using the full palette of modern brain imaging and neuroscience methods, The Neural Bases of Multisensory Processes details current understanding in the neural bases for these phenomena as studied across species, stages of development, and clinical statuses. Organized thematically into nine sub-sections, the book is a collection of contributions by leading scientists in the field. Chapters build generally from basic to applied, allowing readers to ascertain how fundamental science informs the clinical and applied sciences. Topics discussed include: Anatomy, essential for understanding the neural substrates of multisensory processing Neurophysiological bases and how multisensory stimuli can dramatically change the encoding processes for sensory information Combinatorial principles and modeling, focusing on efforts to gain a better mechanistic handle on multisensory operations and their network dynamics Development and plasticity Clinical manifestations and how perception and action are affected by altered sensory experience Attention and spatial representations The last sections of the book focus on naturalistic multisensory processes in three separate contexts: motion signals, multisensory contributions to the perception and generation of communication signals, and how the perception of flavor is generated. The text provides a solid introduction for newcomers and a strong overview of the current state of the field for experts.










Human Movement


Book Description

The sixth edition of this popular text introducing human movement to a range of readers, offers the building blocks, signposts and opportunities to think about the application and integration of basic Human Movement theory. It confirms basic knowledge which is then applied to specific areas. Drawing on the expertise of a range of authors from the healthcare professions, the new edition has adopted a themed approach that links chapters in context. The strength of this current edition is the explicit chapter integration which attempts to mimic the realities of human movement. The themed approach explores the psychosocial influences on movement. Integration is further facilitated by increased cross-referencing between the chapters and the innovative use of one themed case study throughout. Framed about a family unit, this case study enables chapter authors to explicitly apply the content of their chapters to the real world of human movement. Taken as a whole, this more integrated format will enable readers to see the reality and complexity of human movement.




Virtual Reality and Augmented Reality


Book Description

Virtual and Augmented Reality have existed for a long time but were stuck to the research world or to some large manufacturing companies. With the appearance of low-cost devices, it is expected a number of new applications, including for the general audience. This book aims at making a statement about those novelties as well as distinguishing them from the complexes challenges they raise by proposing real use cases, replacing those recent evolutions through the VR/AR dynamic and by providing some perspective for the years to come.
