3 D Sound For Virtual Reality And Multimedia

This is the complete practical introduction to virtual reality and multimedia for those wishing to build systems. It covers the foundations and engineering needed to design and construct projects incorporating video, audio and textural elements and including the use of the latest hardware, to create an artificial world for education, information or entertainment. Production and authoring platforms are described, computer animation and hypertext are covered, but those looking for pages of software listings and computerspeak will be disappointed. This book is about the nuts and bolts: sound and video cards, head mounted displays, CrystalEyes glasses, other 3D glasses for entertainment, audio and video production, and realistic auditory and visual stimulation including stereoscopy. The creation of Cyberspace, and strategies to achieve a complete Cyberatmosphere are presented. Three-dimensional sound generation and video techniques that have never previously been published are revealed. This is the handbook for anyone working in the industry, or hoping to enter it. It also provides a guide for those hoping to 'cross-fertilise' the industry, coming from audio, video, computing or engineering backgrounds. A complete technical guide to MM and VR Includes a Hypertext edition of the book with added audio and graphics on CD Hardware, software, video and never before published 3D audio techniques covered

This book describes recent innovations in 3D media and technologies, with coverage of 3D media capturing, processing, encoding, and adaptation, networking aspects for 3D Media, and quality of user experience (QoE). The main contributions are based on the results of the FP7 European Projects ROMEO, which focus on new methods for the compression and delivery of 3D multi-view video and spatial audio, as well as the optimization of networking and compression jointly across the Future Internet (www.ict-romeo.eu). The delivery of 3D media to individual users remains a highly challenging problem due to the large amount of data involved, diverse network characteristics and user terminal requirements, as well as the user’s context such as their preferences and location. As the number of visual views increases, current systems will struggle to meet the demanding requirements in terms of delivery of constant video quality to both fixed and mobile users. ROMEO will design and develop hybrid-networking solutions that combine the DVB-T2 and DVB-NGH broadcast access network technologies together with a QoE aware Peer-to-Peer (P2P) distribution system that operates over wired and wireless links. Live streaming 3D media needs to be received by collaborating users at the same time or with imperceptible delay to enable them to watch together while exchanging comments as if they were all in the same location. The volume provides state-of-the-art information on 3D multi-view video, spatial audio networking protocols for 3D media, P2P 3D media streaming, and 3D Media delivery across heterogeneous wireless networks among other topics. Graduate students and professionals in electrical engineering and computer science with an interest in 3D Future Internet Media will find this volume to be essential reading.

Overall, this book offers a definitive insight into an emerging sound world that is increasingly becoming part of our everyday lives.

Most events and activities in today's world are ordinarily captured using photos, videos and other multimedia content. Such content has some limitation of storing data and fetching them effectively. Three-dimensional continuous PC animation is the most proper media to simulate these occasions and activities. This book focuses on futuristic trends and innovations in multimedia systems using big data, IoT and cloud technologies. The authors present recent advancements in multimedia systems as they relate to various application areas such as healthcare services and agriculture-related industries. The authors also discuss human-machine interface design, graphics modelling, rendering/animation, image/graphics techniques/systems and visualization. They then go on to explore multimedia content adaptation for interoperable delivery. Finally, the book covers cultural heritage, philosophical/ethical/societal/international issues, standards-related virtual technology and multimedia uses. This book is intended for computer engineers and computer scientists developing applications for multimedia and virtual reality and professionals working in object design and visualization, transformation, modelling and animation of the real world.

3-D Audio Using Loudspeakers is concerned with 3-D audio systems implemented using a pair of conventional loudspeakers. A well-known problem with these systems is the requirement that the listener be properly positioned for the 3-D illusion to function correctly. This book proposes using the tracked position of the listener's head to optimize the acoustical presentation, thus producing a much more realistic illusion over a larger listening area than existing loudspeaker 3-D audio systems. Head-tracking can be accomplished by applying pattern recognition techniques to images obtained from a video camera. Thus, an immersive audio environment can be created without donning headphones or other equipment. 3-D Audio Using Loudspeakers discusses the theory, implementation, and testing of a head-tracked loudspeaker 3-D audio system. Crosstalk cancellers that can be steered to the location of a tracked listener are described. The objective performance of these systems has been evaluated using simulations and acoustical measurements made at the ears of human subjects. Many sound localization experiments were also conducted; the results show that head-tracking both significantly improves localization when the listener is displaced from the ideal listening location, and also enables dynamic localization cues. Much of the theory and experimental results presented are also applicable to loudspeaker 3-D audio systems in general, not just head-tracked ones. 3-D Audio Using Loudspeakers is of interest to researchers studying virtual acoustic displays, and to engineers developing the same. The book serves as a valuable reference to anyone working in this field.

This book showcases cutting-edge research papers from the 9th International Conference on Research into Design (ICoRD 2023) – the largest in India in this area – written by eminent researchers from across the world on design processes, technologies, methods and tools, and their impact on innovation, for supporting design for a connected world. The theme of ICoRD’23 has been ‘Design in the Era of Industry 4.0’. Industry 4.0 signifies the fourth industrial revolution. The first industrial revolution was driven by the introduction of mechanical power such as steam and water engines to replace human and animal labour. The second industrial revolution involved introduction of electrical power and organised labour. The third industrial revolution was powered by introduction of industrial automation. The fourth industrial revolution involves introduction of a combination of technologies to enable connected intelligence and industrial autonomy. The introduction of Industry 4.0 dramatically changes the landscape of innovation, and the way design, the engine of innovation, is carried out. The theme of ICoRD’23 - ‘Design in the Era of Industry 4.0’ –explores how Industry 4.0 concepts and technologies influence the way design is conducted, and how methods, tools, and approaches for supporting design can take advantage of this transformational change that is sweeping across the world. The book is of interest to researchers, professionals, and entrepreneurs working in the areas on industrial design, manufacturing, consumer goods, and industrial management who are interested in the new and emerging methods and tools for design of new products, systems, and services.
