ISBN 978-953-307-093-3 V Preface In everyday life, we use our senses to interact with the environment. We can see, touch, smell, hear and taste the external world surrounding us through interactions that usually occur with an initial contact between an organism and its environment. Particularly, we have physical experiences such as texture, stiffness, and resistance to movement through our sense of touch. To experience these in virtual environments (VEs), computer interfaces are required to enable us to interact with virtual objects. Haptic technology enables computer users to touch and/or manipulate virtual or remote objects in virtual environments or tele-operation systems. If haptic cues (e.g., touch sensations) are displayed in addition to visual and auditory cues, these VEs are called haptic-enabled virtual environments. Haptic interfaces are divided into two main categories: force feedback and tactile. Force feedback interfaces are used to explore and modify remote/virtual objects in three physical dimensions in applications including computer-aided design, computer-assisted surgery, and computer-aided assembly. Tactile interfaces deal with surface properties such as roughness, smoothness, and temperature. Haptic research is intrinsically multi-disciplinary, incorporating computer science/ engineering, control, robotics, psychophysics, and human motor control. By extending the scope of research in haptics, advances can be achieved in existing applications such as computer-aided design (CAD), tele-surgery, rehabilitation, scientic visualization, robot- assisted surgery, authentication, and graphical user interfaces (GUI), to name a few. Advances in Haptics presents a number of recent contributions to the eld of haptics. Authors from around the world present the results of their research on various issues in the eld of haptics. The contributions are organized in ve sections: Section I deals with the design, control, and analysis of haptic interfaces. Issues such as stability and achievable performance of haptic interfaces are addressed. Stability is one of the main issues in the control of haptic interfaces. Instability might cause an undesirable feeling to the user and unrealistic interaction with the virtual environment. Stability and achievable performance of a haptic system are among the fundamental indices for evaluation of a high- precision stable haptic rendering. VI In Section II, several important issues are addressed in the haptic rendering of haptic-enabled VEs. The contributed chapters in this section deal with the development and enhancement of algorithms and software associated with generating, transmitting, and rendering the feel of virtual objects. Section III covers several human factors studies that investigate the effects of various factors on user perception and performance in various applications of haptics. Haptic applications require interactions between humans and computers. Due to the complexity and variability of the user’s physical motion, it is difcult to generate a precise mathematical description of human motor control behavior. In addition, to ensure that VEs are compatible with users, VE designers need knowledge about human perception to obtain an understanding of design constraints inuenced by sensory perception. Thus, human factors studies are required to recognize the limitations and capabilities of the user. Section IV presents topics focusing on various aspects of the haptic interaction between humans and computers. An understanding of the nature of user-computer interaction is essential for the design of haptic interfaces. Several interaction issues are investigated to ensure the effectiveness of haptic interfaces. The results of these studies can improve the design of usable and effective haptic interfaces. Finally, Section V presents recent selected applications in the eld of haptics. Mehrdad Hosseini Zadeh, Ph.D Grand Blanc, Michigan April 2010 VII Contents Preface V I.
