During the past decade, high-performance computer graphics have found application in an exciting and expanding range of new domains. Among the most dramatic developments has been the incorporation of real-time interactive manipulation and display for human figures. Though actively pursued by several research groups, the problem of providing a synthetic or surrogate human for engineers and designers already familiar with computer-aided design techniques was most comprehensively solved by Norman Badler's Computer Graphics Laboratory at the University of Pennsylvania. The breadth of that effort as well as the details of its methodology and software environment are presented in this volume. The book is intended for human factors engineers interested in understanding how a computer-graphics surrogate human can augment their analyses of designed environments. It will also inform design engineers of the state of the art in human figure modeling, and hence of the human-centered design central to the emergent concept of concurrent engineering. In fulfilling these goals, the book additionally documents for the entire computer graphics community a major research effort in the interactive control of articulated human figures.

First published in 1979, this book starts from the perspective that dealing with anaphoric language can be decomposed into two complementary tasks: 1. identifying what a text potentially makes available for anaphoric reference and 2. constraining the candidate set of a given anaphoric expression down to one possible choice. The author argues there is an intimate connection between formal sentential analysis and the synthesis of an appropriate conceptual model of the discourse. Some of the issues with the creation of this conceptual model are discussed in the second chapter, which follows a background to the thesis that catalogues the types of anaphoric expression available in English and lists the types of things that can be referred to anaphorically. The third and fourth chapters examine two types of anaphoric expression that do not refer to non-linguistic entities. The final chapter details three areas into which this research could potentially be extended. This book will be of interest to students of linguistics.
