Most industrial robots today have little or no sensory capability. Feedback is limited to information about joint positions, combined with a few interlock and timing signals. These robots can function only in an environment where the objects to be manipulated are precisely located in the proper position for the robot to grasp (i. e. , in a structured environment). For many present industrial applications, this level of performance has been adequate. With the increasing demand for high performance sensor-based robot manipulators in assembly tasks, meeting this demand and challenge can only be achieved through the consideration of: 1) efficient acquisition and processing of intemaVextemal sensory information, 2) utilization and integration of sensory information from various sensors (tactile, force, and vision) to acquire knowledge in a changing environment, 3) exploitation of inherent robotic parallel algorithms and efficient VLSI architectures for robotic computations, and finally 4) system integration into a working and functioning robotic system. This is the intent of the Workshop on Sensor-Based Robots: Algorithms and Architectures - to study the fundamental research issues and problems associated with sensor-based robot manipulators and to propose approaches and solutions from various viewpoints in improving present day robot manipula tors in the areas of sensor fusion and integration, sensory information processing, and parallel algorithms and architectures for robotic computations.

The CISM-IFToMM Symposia have played a dynamic role in the development of the theory and practice of robotics. The proceedings of the Tenth Symposia present a world view to date of the state-of-the-art, including a unique record of the results achieved in central and eastern Europe.

Assessment has long been recognized as a key feature in learning efficacy, especially through formative evaluation. Item banking, the storage and classification of test items, is an essential part of systematic assessment. This volume is based on a NATO Advanced Research Workshop held as part of the Special Programme on Advanced Educational Technology. The workshop brought together scholars from around the world to discuss and critically analyze the issues and problems associated with Subjective Probability Measurement (SPM) or the more generic research area called self-assessment. Recent advances in computer technology (expert systems, interactive video disks, and hypermedia) along with the developing sophistication of self-assessment scoring systems based on SPM made this conference particularly important and timely. The book is divided into three main parts: - The input: item banking and hypermedia - The process: subjective probabilities - The output: teaching and learning feedbacks. In summary, although SPM is a difficult theoretical concept for most educators to comprehend, the sophisticated nature of modern computer systems coupled with comprehensive formative and summative evaluation and self-assessment systems make SPM transparent to the user.

This book is a collection of some of the papers that were presented during a NATO Advanced Research Workshop (ARW) on "Intelligent Systems: Safety, Reliability and Maintainability Issues" that was held in Kusadasi, Turkey during August 24- 28, 1992. Attendance at this workshop was mainly by invitation only, drawing people internationally representing industry, government and the academic community. Many of the participants were internationally recognized leaders in the topic of the workshop. The purpose of the ARW was to bring together a highly distinguished group of people with the express purpose of debating where the issues of safety, reliability and maintainability place direct and tangible constraints on the development of intelligent systems. As a consequence, one of the major debating points in the ARW was the definition of intelligence, intelligent behaviour and their relation to complex dynamic systems. Two major conclusions evolved from the ARW are: 1. A continued need exists to develop formal, theoretical frameworks for the architecture of such systems, together with a reflection on the concept of intelligence. 2. There is a need to focus greater attention to the role that the human play in controlling intelligent systems. The workshop began by considering the typical features of an intelligent system. The complexity associated with multi-resolutional architectures was then discussed, leading to the identification of a necessity for the use of a combinatorial synthesis/approach. This was followed by a session on human interface issues.

The objective of the NATO Advanced Research Workshop "Learning electricity and electronics with advanced educational technology" was to bring together researchers coming from different domains. Electricity education is a domain where a lot of research has already been made. The first meeting on electricity teaching was organized in 1984 by R. Duit, W. Jung and C. von Rhoneck in Ludwigsburg (Germany). Since then, research has been going on and we can consider that the workshop was the successor of this first meeting. Our goal was not to organize a workshop grouping only people producing software in the field of electricity education or more generally in the field of physics education, even if this software was based on artificial intelligence techniques. On the contrary, we wanted this workshop to bring together researchers involved in the connection between cognitive science and the learning of a well defined domain such as electricity. So during the workshop, people doing research in physics education, cognitive psychology, and artificial intelligence had the opportunity to discuss and exchange. These proceedings reflect the different points of view. The main idea is that designing a learning environment needs the confrontation of different approaches. The proceedings are organized in five parts which reflect these different aspects.

Control technology is a new learning environment which offers the opportunity to take up the economic and educational challenge of enabling people to adapt to new technologies and use them to solve problems. Giving young children (and also adults) easy access to control technology introduces them to a learning environment where they can build their knowledge across a range of topics. As they build and program their own automata and robots, they learn to solve problems, work incollaboration, and be creative. They also learn more about science, electronics, physics, computer literacy, computer assisted manufacturing, and so on. This book, based on a NATO Advanced Research Workshop in the Special Programme on Advanced Educational Technology, presents a cross-curricular approach to learning about control technology. The recommended methodology is active learning, where the teacher's role is to stimulate the learner to build knowledge by providing him/her with appropriate materials (hardware and software) and suggestions to develop the target skills. The results are encouraging, although more tools are needed to help the learner to generalize from his/her concrete experiment in control technology as well as to evaluate its effect on the target skills. The contributions not only discuss epistemological controversies linked to such learning environments as control technology, but also report on the state of the art and new developments in the field and present some stimulating ideas.

Despite its increasing importance, the verification and validation of the human-machine interface is perhaps the most overlooked aspect of system development. Although much has been written about the design and developmentprocess, very little organized information is available on how to verifyand validate highly complex and highly coupled dynamic systems. Inability toevaluate such systems adequately may become the limiting factor in our ability to employ systems that our technology and knowledge allow us to design. This volume, based on a NATO Advanced Science Institute held in 1992, is designed to provide guidance for the verification and validation of all highly complex and coupled systems. Air traffic control isused an an example to ensure that the theory is described in terms that will allow its implementation, but the results can be applied to all complex and coupled systems. The volume presents the knowledge and theory ina format that will allow readers from a wide variety of backgrounds to apply it to the systems for which they are responsible. The emphasis is on domains where significant advances have been made in the methods of identifying potential problems and in new testing methods and tools. Also emphasized are techniques to identify the assumptions on which a system is built and to spot their weaknesses.

Educational technology in the broadest sense is knowledge and competence forimproving the educational process: for using hardware (equipment), software (methods), and "underware" (underlying organizational structures). This volume in the Special Programme on Advanced Educational Technology presents the results of a NATO Advanced Research Workshop on educational systems design as a new educational technology. The objective of the workshop was toadvance our knowledge about the comprehensive systems design approach for improving educational systems. The workshop was organized for the transdisciplinary interaction of three scientific groups representing design science, organizational/systems science, and educationaltechnology. Participants were selected based on their scholarship as members of one or more of these three groups. The book opens with theframing papers sent by the editors to participants prior to the workshop, then presents five sets of thematic contributions: the conceptual and empirical contexts of comprehensive systems design, the systems design focus, a systems view of designing educational systems, the educational context of systems design, and high technology focus in systems design.

What the book is about This book is about the theory and practice of the use of multimedia, multimodal interfaces for leaming. Yet it is not about technology as such, at least in the sense that the authors do not subscribe to the idea that one should do something just because it is technologically possible. 'Multimedia' has been adopted in some commercial quarters to mean little more than a computer with some form of audio ar (more usually) video attachment. This is a trend which ought to be resisted, as exemplified by the material in this book. Rather than merely using a new technology 'because it is there', there is a need to examine how people leam and eommunicate, and to study diverse ways in which computers ean harness text, sounds, speech, images, moving pietures, gestures, touch, etc. , to promote effective human leaming. We need to identify which media, in whieh combinations, using what mappings of domain to representation, are appropriate far which educational purposes . . The word 'multimodal ' in the title underlies this perspective. The intention is to focus attention less on the technology and more on how to strueture different kinds of information via different sensory channels in order to yield the best possible quality of communication and educational interaction. (Though the reader should refer to Chapter 1 for a discussion of the use of the word 'multimodal' . ) Historically there was little problem.

Magical describes conditions that are outside our understanding of cause and effect. Even in modern societies, magic-based explanations are powerful because, given the complexity of the universe, there are so many opportunities to use them. The history of medicine is defined by progress in understanding the human body - from magical explanations to measurable results. To continue medical progress, physicians and scientists must openly question traditional models. For thirteen years, MMVR has been an incubator for technologies that create new medical understanding via the simulation, visualization, and extension of reality. Researchers create imaginary patients because they offer a more reliable and controllable experience to the novice surgeon. With imaging tools, reality is purposefully distorted to reveal to the clinician what the eye alone cannot see. Robotics and intelligence networks allow the healer's sight, hearing, touch, and judgment to be extended across distance, as if by magic. The moments when scientific truth is suddenly revealed after lengthy observation, experimentation, and measurement is the real magic. These moments are not miraculous, however. book.
