Haptics Technologies: Bringing Touch to Multimedia (Springer Series on Touch and Haptic Systems)
Mauricio Orozco, Mohamad Eid
Format: PDF / Kindle (mobi) / ePub
The term “haptics” refers to the science of sensing and manipulation through touch. Multiple disciplines such as biomechanics, psychophysics, robotics, neuroscience, and software engineering converge to support haptics, and generally, haptic research is done by three communities: the robotics community, the human computer interface community, and the virtual reality community.
This book is different from any other book that has looked at haptics. The authors treat haptics as a new medium rather than just a domain within one of the above areas. They describe human haptic perception and interfaces and present fundamentals in haptic rendering and modeling in virtual environments. Diverse software architectures for standalone and networked haptic systems are explained, and the authors demonstrate the vast application spectrum of this emerging technology along with its accompanying trends. The primary objective is to provide a comprehensive overview and a practical understanding of haptic technologies. An appreciation of the close relationship between the wide range of disciplines that constitute a haptic system is a key principle towards being able to build successful collaborative haptic environments.
Structured as a reference to allow for fast accommodation of the issues concerned, this book is intended for researchers interested in studying touch and force feedback for use in technological multimedia systems in computer science, electrical engineering, or other related disciplines. With its novel approach, it paves the way for exploring research trends and challenges in such fields as interpersonal communication, games, or military applications.
information representation, synchronization, haptic APIs, existing haptic software frameworks, such as Reachin and Novint e-Touch, and haptic programming toolkits. The chapter elaborates on the discussion of networked haptics (commonly referred to as the Collaborative Haptic Audio Visual Environment (C-HAVE)). Some characteristics, such as quality of experience and security, are also highlighted. 20 1 Haptics: General Principles 1.9 Further Reading about Haptics In recent years, there has
distortion, and aberration, of which further information can be found in . Roughness measures the small-scale variations in the height of a physical surface; indeed, Klatzky et al.  have stated that “surface roughness is particularly salient to the tactile sense”. Several studies and experiments have been conducted to quantify roughness of texture elements. For instance, Cascio and Sathian found that temporal cues do indeed contribute to tactile texture perception . It has been

Furthermore, the trend of integrating haptics into mobile devices, or the development of mobile haptic devices, is limited by the 4.5 Performance Specifications 81 weight and size of the device. In some cases, a larger size is unavoidable since large areas of the human body must experience stimuli to provide the intended perception. 4.5.2 Spatial Attributes 1. Workspace. The area or volume in real world space that the end-effector of a haptic device can reach is
which was originally proposed in , can be used in these cases. DIBR uses two images for each video frame: the RGB image and the depth image. Several advantages of using DIBR have been pinpointed in . First, existing methods of image processing and compression can be applied to DIBR due to its simple and regular 5.8 Haptic Rendering of More Than 3-DOF 123 structure. Second, real-world objects and scenes can be rendered without the need for millions of polygons and expensive
whether the incorporation of haptic modality in multimedia systems would enhance the overall quality of user experience. Furthermore, questions can be raised as to how the advantages of enhanced senses outweigh the costs of adapting to a new technology. Moreover, how will users experience such advantages, and will they be overwhelmed or exhausted from interacting with multiple media?
