This book introduces the latest progress in six degrees of freedom (6-DoF) haptic rendering with the focus on a new approach for simulating force/torque feedback in performing tasks that require dexterous manipulation skills. One of the major challenges in 6-DoF haptic rendering is to resolve the conflict between high speed and high fidelity requirements, especially in simulating a tool interacting with both rigid and deformable objects in a narrow space and with fine features. The book presents a configuration-based optimization approach to tackle this challenge. Addressing a key issue in many VR-based simulation systems, the book will be of particular interest to researchers and professionals in the areas of surgical simulation, rehabilitation, virtual assembly, and inspection and maintenance.

The human haptic system, among all senses, provides unique and bidirectional communication between humans and their physical environment. Yet, to date, most human-computer interactive systems have focused primarily on the graphical rendering of visual information and, to a lesser extent, on the display of auditory information. Extending the frontier of visual computing, haptic interfaces, or force feedback devices, have the potential to increase the quality of human-computer interaction by accommodating the sense of touch. They provide an attractive augmentation to visual display and enhance the level of understanding of complex data sets. They have been effectively used for a number of applications including molecular docking, manipulation of nano-materials, surgical training, virtual prototyping, and digital sculpting. Compared with visual and auditory display, haptic rendering has extremely demanding computational requirements. In order to maintain a stable system while displaying smooth and realistic forces and torques, high haptic update rates in the range of 500-1000 Hz or more are typically used. Haptics present many new challenges to researchers and developers in computer graphics and interactive techniques. Some of the critical issues include the development of novel data structures to encode shape and material properties, as well as new techniques for geometry processing, data analysis, physical modeling, and haptic visualization. This synthesis examines some of the latest developments on haptic rendering, while looking forward to exciting future research in this area. It presents novel haptic rendering algorithms that take advantage of the human haptic sensory modality. Specifically it discusses different rendering techniques for various geometric representations (e.g. point-based, polygonal, multiresolution, distance fields, etc), as well as textured surfaces. It also shows how psychophysics of touch can provide the foundational design guidelines for developing perceptually driven force models and concludes with possible applications and issues to consider in future algorithmic design, validating rendering techniques, and evaluating haptic interfaces.

This book covers all topics relevant for the design of haptic interfaces and teleoperation systems. The book provides the basic knowledge required for understanding more complex approaches and more importantly it introduces all issues that must be considered for designing efficient and safe haptic interfaces. Topics covered in this book provide insight into all relevant components of a haptic system. The reader is guided from understanding the virtual reality concept to the final goal of being able to design haptic interfaces for specific tasks such as nanomanipulation. The introduction chapter positions the haptic interfaces within the virtual reality context. In order to design haptic interfaces that will comply with human capabilities at least basic understanding of human sensors-motor system is required. An overview of this topic is provided in the chapter related to human haptics. The book does not try to introduce the state-of-the-art haptic interface solutions because these tend to change quickly. Only a careful selection of different kinematic configurations is shown to introduce the reader into this field. Mathematical models of virtual environment, collision detection and force rendering topics are strongly interrelated and are described in the next two chapters. The interaction with the virtual environment is simulated with a haptic interface. Impedance and admittance based approaches to haptic robot control are presented. Stability issues of haptic interaction are analyzed in details and solutions are proposed for guaranteeing stable and safe operation. Finally, haptic interaction is extended to teleoperation systems. Virtual fixtures which improve the teleoperation and human-robot cooperation in complex environments are covered next and the last chapter presents nanomanipulation as one specific example of teleoperation.

The sense of touch is fundamental during the interaction between humans and their environment; in virtual reality, objects are created by computer simulations and they can be experienced through haptic devices. In this context haptic textures are fundamental for a realistic haptic perception of virtual objects. This book formalizes the specific artefacts corrupting the rendering of virtual haptic textures and offers a set of simple conditions to guide haptic researchers towards artefact-free textures. The conditions identified are also extremely valuable when designing psychophysical experiments and when analyzing the significance of the data collected. The Synthesis of Three Dimensional Haptic Textures, Geometry, Control, and Psychophysics examines the problem of rendering virtual haptic textures with force feedback devices. The author provides an introduction to the topic of haptic textures that covers the basics of the physiology of the skin, the psychophysics of roughness perception, and the engineering challenges behind haptic textures rendering. The book continues with the presentation of a novel mathematical framework that characterizes haptic devices, texturing algorithms and their ability to generate realistic haptic textures. Finally, two psychophysical experiments link the perception of roughness with the parameters of the haptic rendering algorithms. This book formalizes the specific artefacts corrupting the rendering of virtual haptic textures and offers a set of simple conditions to guide haptic researchers towards artefact-free textures. The conditions identified are also extremely valuable when designing psychophysical experiments and when analyzing the significance of the data collected.

Abstract: Abstract of thesis entitled HAPTIC RENDERING OF THREE-DIMENSIONAL HETEROGENEOUS FEATURES Submitted by Lian Lili for the degree of Doctor of Philosophy at The University of Hong Kong in February 2007 Haptic interaction provides the operator a full immersion in the virtual environment by offering an additional communication modality - the force feedback between the user and the computer. In recent years, haptic related research has attracted intensive interest, but most previous work has been restricted to modeling and haptic rendering of virtual models with homogeneous features. This study focuses on the haptic rendering algorithms of three-dimensional heterogeneous features and their applications to product design. In this study, heterogeneous features are characterized as both material and geometric variations, and haptic rendering of heterogeneous features is implemented in three disciplines. The first discipline focuses on the haptic rendering of heterogeneous rough surface and frictional surface of rigid objects. The haptic rendering of roughness and friction is implemented based on the generation of fine surface features. Three-dimensional geometric variations of fine surface features are created by a procedural method followed by a feature mapping approach. Improvement of the lateral-force algorithm and the Karnopp-based algorithm is developed to haptically render heterogeneous surface roughness and friction. The second discipline focuses on the haptic rendering of deflection or small deformation of an object consisted of heterogeneous materials. Haptic rendering of flexible objects is attributed in between haptic rendering of rigid objects and that of deformable objects. Therefore, a pseudo-rigid-body model is developed to model the flexible object and calculate the feedback forces. Pseudo-rigid-body models consisting of different materials are assembled in a certain way to simulate a heterogeneous object. The proposed approach is also applied to a haptic aided product design case study. In the third discipline, the haptic rendering of deformable objects composed of heterogeneous materials is investigated. A multi-layer mass-spring system is used to represent the deformable object. The relationship between the physical properties of the materials being simulated and the physical parameters of the model is investigated. A surface-based force-mapping method is developed to haptically display the proposed mass-spring system. This method simplifies a volume-based model into a surface-based model and maintains the material information of the inner volume of the model simultaneously. As a result, the haptic rendering of heterogeneous material objects can be realized. Furthermore, system computation acceleration is implemented by a proposed multi-resolution and multi-rate method.
