This book is about the two-way interplay between vision and action. Vision acts to guide and control actions. But vision also obtains a lot of information about the world by virtue of these actions --for example by moving round an object to obtain successive views. This becomes a reiterative process and it is this that is the focus of this volume. This book contains contributions from scientists who are leaders in each of the several facets of the subject. Examples of the types of action considered vary from moving the eyes and head and body, as in looking around or walking, to complex actions such as driving a car, or playing table tennis.

From recent developments in the rapidly growing area of neuroscience it has become increasingly clear that a simplistic description of brain function as a broad collection of simple input-output relations is quite inadequate. Introspection already tells us that our motor behavior is guided by a complex interplay between many inputs from the outside world and from our internal "milieu," internal models of ourselves and the outside world, memory content, directed attention, volition, and so forth. Also, our motor activity normally involves more than a circumscribed group of muscles, even if we intend to move only one effector organ. For example, a reaching movement or a reorientation of a sensory organ almost invariably requires a pattern of preparatory or assisting activities in other parts of the body, like the ones that maintain the body's equilibrium. The present volume is a summary of the papers presented at the symposium "Sensory Interaction in Posture and Movement Control" that was held at Smolenice Castle near Bratislava, Slovakia, as a Satellite Symposium to the ENA Meeting 1994 in Vienna. The focus of this meeting was not only restricted to the "classical" sensory interactions such as between vestibular and visual signals, or between otolith and semicircular canal inputs. Rather, the symposium tried to consider also the interplay between perception and action, between reflexive and volitional motor acts as well as between sensory driven or self-initi ated motor acts and reafferent inputs.

We make 3-5 eye movements per second, and these movements are crucial in helping us deal with the vast amounts of information we encounter in our everyday lives. In recent years, thanks to the development of eye tracking technology, there has been a growing interest in monitoring and measuring these movements, with a view to understanding how we attend to and process the visual information we encounter Eye tracking as a research tool is now more accessible than ever, and is growing in popularity amongst researchers from a whole host of different disciplines. Usability analysts, sports scientists, cognitive psychologists, reading researchers, psycholinguists, neurophysiologists, electrical engineers, and others, all have a vested interest in eye tracking for different reasons. The ability to record eye-movements has helped advance our science and led to technological innovations. However, the growth of eye tracking in recent years has also presented a variety of challenges - in particular the issue of how to design an eye-tracking experiment, and how to analyse the data. This book is a much needed comprehensive handbook of eye tracking methodology. It describes how to evaluate and acquire an eye-tracker, how to plan and design an eye tracking study, and how to record and analyse eye-movement data. Besides technical details and theory, the heart of this book revolves around practicality - how raw data samples are converted into fixations and saccades using event detection algorithms, how the different representations of eye movement data are calculated using AOIs, heat maps and scanpaths, and how all the measures of eye movements relate to these processes. Part I presents the technology and skills needed to perform high-quality research with eye-trackers. Part II covers the predominant methods applied to the data which eye-trackers record. These include the parsing of raw sample data into oculomotor events, and how to calculate other representations of eye movements such as heat maps and transition matrices. Part III gives a comprehensive outline of the measures which can be calculated using the events and representations described in Part II. This is a taxonomy of the measures available to eye-tracking researchers, sorted by type of movement of the eyes and type of analysis. For anyone in the sciences considering conducting research involving eye-tracking, this book will be an essential reference work.

The 19th century pioneers of motor physiology - Helmholtz, Hering, Fick and others - used the mathematics of motion, known as kinematics, to describe the laws of human movement and to deduce the neural control principles underlying these laws. After long neglect - partly due to limitations in stimulation and recording techniques - the kinematic approach is now resurging, fortified with modern computers and electrophysiology. New developments in recording techniques, as well as an improved understanding of the complex control properties of three-dimensional movements, have led to a flood of new research in this area. The classical laws of Donders and Listing have been confirmed and generalized, and computer simulations of the neural control of three-dimensional movement have been developed and tested. In this book, some of the world's leading scientists of motor control discuss how the brain represents and tranforms the kinematic variables of movement. Background chapters explain the basic concepts - non-commutativity, redundancy and the classical laws - and their application to normal function and motor disorders, and shorter articles describe current research. The contributions are based on presentations at a symposium held in Tübingen in August 1995. The wide scope of the book should enable researchers to gain an overview of current research, but should also help newcomers tot he field to get a good understanding of the questions and problems involved in three-dimensional movement control.

Vision and Goal-Directed Movement: Neurobehavioral Perspectives is also available as an e-book. The e-book is available at a reduced price and allows readers to highlight and take notes throughout the text. When purchased through the Human Kinetics Web site, access to the e-book is immediately granted when the order is received. To interact with the environment, an individual must code, store, and translate spatial information into the appropriate motor commands for achieving an outcome. Working from this premise, Vision and Goal-Directed Movement: Neurobehavioral Perspectives discusses how visual perception, attention, and memory are linked to the processes of movement preparation and execution. With contributions from active researchers in movement science, Vision and Goal-Directed Movement presents the latest theories on the utilization of vision in goal-directed movement control. As a resource for motor control and motor learning researchers, students, educators, and clinicians, Vision and Goal-Directed Movement offers the following: • Comprehensive coverage of current behavior-based literature on the visual control of goal-directed movement • A systematic explication of the sensory and physiological processes and systems responsible for fast, accurate, and efficient performance • A solid foundation for further study of the sensory and neural systems responsible for precise goal-directed behavior • A discussion of how current research on vision and goal-directed movement can assist in creating efficient and safe work environments Using research informed by neural imaging and magnetic brain stimulation, this text provides readers with a better understanding of the neural foundations for goal-directed movement, illustrates the flexibility of the human visuomotor system, and discusses how regulation of movements depends on the learning and developmental history of the performer. It begins by reviewing the works of R.S. Woodworth and the influence of his theories on current research. The majority of the chapters in the first section of the book take a behavioral and process-oriented approach to exploring goal-directed movement. The text then explores the sensory and neural foundations for goal-directed action, including issues related to both pursuit and saccadic eye movements as well as discussion of the specialization of various cortical systems for the regulation of movement. Especially relevant to professionals and scientists concerned with skill instruction and rehabilitation, the final part of the text provides a review of recent research on how and why limb control changes occur with practice and development. In addition, Vision and Goal-Directed Movement considers how the research presented can maximize precision, efficiency, and safety in workspace design. Vision and Goal-Directed Movement: Neurobehavioral Perspectives adds a unique offering to the literature base for motor behavior, demonstrating how advances in both behavioral and neurophysiological methods can inform theories related to the biological systems contributing to skilled performance.

This volume contains the proceedings of the Ninth European Conference on Eye Movements (ECEM 9), held in Ulm, Germany, on September 23-26, 1997. ECEM 9 con tinued a series of conferences initiated by Rudolf Groner of Bern, Switzerland, in 1981 which, from its very beginning, has brought together scientists from very diverse fields with a common interest in eye movements. About 40 of the papers presented at ECEM 9 have been selected for presentation in full length while others are rendered in condensed form. There is a broad spectrum of motives why people have become involved in, and fas cinated by, eye movement research. Neuroscientists have been allured by the prospect of understanding anatomical findings, single unit recordings, and the sequels of experimental lesions in terms of the clearly defined system requirements and the well documented be havioural repertoire of the oculomotor system. Others have been attracted by the richness of this repertoire and its dependence on an intricate hierarchy of factors spanning from "simple" reflexes to visual pattern recognition and spatio-temporal prediction. Neurolo gists, neuro-ophthalmologists and neuro-otologists have long standing experience with eye movements as sensitive indicators of lesions in the brain stem, the midbrain, and the cere bellum. By studying oculomotor malfunctions they have made, and are continuing to make, important contributions to our understanding of oculomotor functions.
