Knowledge-based systems are increasingly found in a wide variety of settings and this handbook has been written to meet a specific need in their widening use. While there have been many successful applications of knowledge-based systems, some applications have failed because they never received the corrective feedback that evaluation provides for keeping development focused on the users' needs in their actual working environment. This handbook provides a conceptual framework and compendium of methods for performing evaluations of knowledge-based systems during their development. Its focus is on the users' and subject matter experts' evaluation of the usefulness of the system, and not on the developers' testing of the adequacy of the programming code. The handbook permits evaluators to systematically answer the following kinds of questions: Does the knowledge-based system meet the users' task requirements? Is the system easy to use? Is the knowledge base logically consistent? Does it meet the required level of expertise? Does the system improve performance? The authors have produced a handbook that will serve two audiences: a tool that can be used to create knowledge-based systems (practitioners, developers, and evaluators) and a framework that will stimulate more research in the area (academic researchers and students). To accomplish this, the handbook is built around a conceptual framework that integrates the different types of evaluations into the system of development process. The kinds of questions that can be answered, and the methods available for answering them, will change throughout the system development life cycle. And throughout this process, one needs to know what can be done, and what can't. It is this dichotomy that addresses needs in both the practitioner and academic research audiences.

User Interface Design and Evaluation provides an overview of the user-centered design field. It illustrates the benefits of a user-centered approach to the design of software, computer systems, and websites. The book provides clear and practical discussions of requirements gathering, developing interaction design from user requirements, and user interface evaluation. The book's coverage includes established HCI topics—for example, visibility, affordance, feedback, metaphors, mental models, and the like—combined with practical guidelines for contemporary designs and current trends, which makes for a winning combination. It provides a clear presentation of ideas, illustrations of concepts, using real-world applications. This book will help readers develop all the skills necessary for iterative user-centered design, and provides a firm foundation for user interface design and evaluation on which to build. It is ideal for seasoned professionals in user interface design and usability engineering (looking for new tools with which to expand their knowledge); new people who enter the HCI field with no prior educational experience; and software developers, web application developers, and information appliance designers who need to know more about interaction design and evaluation. Co-published by the Open University, UK. Covers the design of graphical user interfaces, web sites, and interfaces for embedded systems. Full color production, with activities, projects, hundreds of illustrations, and industrial applications.

Abstract: "This paper investigates the possibilit[i]es of supporting user interface design and evaluation by means of a knowledge-based critiquing approach. We describe a prototype system called KRI that was developed in order to investigate the feasibility of a critiquing approach and to point to potential problems. The rest of the paper is concerned with a possible way of integrating a knowledge-based critiquing module with a conventional User Interface Management System (UIMS). We recognize the need for support as well in the design phase as in evaluating the runtime log, and discuss requirements on the user interface representation of the UIMS when a design and evaluation support module is considered, and finally evaluate a particular representation language (the User Interface Language of Digital's XUI Toolkit) from this point of view."

Conceptual Design is one of the few areas of Engineering Design where computers have yet to make an impact. With the development of Knowledge Based Systems it is now possible to rectify this situation. This publication deals with the use of Knowledge Based Systems (KBS) as tools for conceptual design. Included are neglected aspects such as evaluation and user needs. Practical Knowledge Based Systems in Conceptual Design is based on the authors' experience of developing KBS for use in civil engineering, an area of industrial application which is recognised as being one of great potential. The methodology has been tried and tested by designers. Examples of systems which have been developed to solve specific design problems are included.

"This book compiles authoritative research from scholars worldwide, covering the issues surrounding the influx of information technology to the office environment, from choice and effective use of technologies to necessary participants in the virtual workplace"--Provided by publisher.

A companion to the author's User Interface Evaluation, this book details a systematic and comprehensive methodology to measure and evaluate new or existing human-computer interfaces. The text will serve both as a reference source, and as a supplement to its sister volume.
