Computer systems which interact with human users to collect, update or provide information are growing more complex. Additionally, users are demanding more thorough testing of all computer systems. Because of the complexity and thoroughness required, automation of interactive systems testing is desirable, especially for functional testing. Many currently available testing tools, like program proving, are impractical for testing large systems. The solution presented here is the development of an automated test system which simulates human users. This system incorporates a high-level programming language, ATLIS. ATLIS programs are compiled and interpretively executed. Programs are selected for execution by operator command, and failures are reported to the operator's console. An audit trail of all activity is provided. This solution provides improved efficiency and effectiveness over conventional testing methods.

This dissertation presents the GDI (Goal Directed Interface) approach to the user interface for office systems. The primary objectives of the approach are to create an interface that (1) requires little user training and (2) tries to perform higher level task activities (ex. 'schedule a meeting') that have been excluded from computerization in the past. The GDI technique (1) postulates a simple model of the office environment consisting of persons, things, and processes, and a decomposable goal set, (2) represents knowledge in the office environment through rules, frames, and scripts, and object-oriented programming techniques, (3) creates an iconic visual representation consisting of persons, things, and processes that closely mimics the user's 'mental model' of the office world, (4) requires that the user's own 'person icon' be present for all interactions so that actions appear to take place in a user controllable context (the user's icon is, literally, in the interface), (5) provides a 'selection window' through which the user communicates his/her goal by grouping relevant icons, (6) uses a rule-based expert system to examine an icon configuration and, through its expertise, derives a user goal (despite ambiguous or faulty icon placements), (7) attempts to complete the user goal through the use of scripts and multiple expert systems.

This paper describes a Protocol Finite State Machine (PFSM) for implementing communication protocols. Our objective is to develop and implement a general model for communication protocols based on the principles of finite state machines and make the design of transport entity more modular and easier to maintain and modify. We have designed an inference method and knowledge representation, based on semantic networks, for implementing this model. We have added interactive capability and automatic error detection to check for invalid external events and other types of errors in our model. PFSM consists of one or more knowledge bases depicting the state machine model for each communication protocol, an inference engine that uses the knowledge base(s), a working memory, a knowledge acquisition subsystem to gather the data required to build the knowledge base(s), a dialog subsystem to conduct an interactive conversation with the user(s), and an explanation subsystem to explain the inferencing mechanism.

Computer Aided Teaching System (CATSY) is an interactive graphics system, utilizing current microcomputer technology, along with a graphics tablet and a large screen projection system to enhance lecture presentations. Included in this thesis are descriptions of the supporting graphics software (POLY-ReGIS) and the computer peripherals used in the development of CATSY.The development of interactive graphics is stressed in this thesis. Applications of these graphics to CATSY are presented and an introduction to the data structures used in this system is also given. This thesis is intended to support and complement the masters thesis presented by Mr. John Raab, which deals primarily with the system implementation, data structures and the text editor used in CATSY.

VIDEODISC IN ARCHIVES AND ROTCH VISUAL COLLECTIONS. / Includes bibliographical references (leaves 87-90). / A technique of pictorially synthesizing facial imagery using optical videodiscs under computer control is described. Search, selection and averaging processes are performed on a catalogue of whole faces and facial features to yield a composite, expressive, recognizable face. An immediate application of this technique is the reconstruction of a particular face from memory for police identification, thus the project is called , IDENTIDISC. Part I-PACEMAKER describes the production and implementation of the IDENTIDISC system to produce composite faces. Part II-EXPRESSIONMAKER describes animation techniques to add expression and motion to composite faces . Expression sequences are manipulated to make 'anyface' make any face. Historical precedents of making facial composites, theories of facial recognition, classification and expression are also discussed. This thesis is accompanied by two copies of PACEMAKER-III, an optical videodisc produced at the Architecture Machine Group in 1982. The disc can be played on an optical videodisc player . The length is approximately 15 , 0000 frames. Frame numbers are indicated in the text by [ ]. / by Peggy Weil. / M.S.V.S.

Thesis (M.S.V.S.)--Massachusetts Institute of Technology, Dept. of Architecture, 1982. / MICROFICHE COPY AVAILABLE IN ARCHIVES AND ROTCH. / Bibliography: leaves 111-116. / The human face is a highly significant visual display which we are able to remember and recognize easily despite the fact that we are exposed to thousands of faces which may be metrically very similar. caricature is a graphical coding of facial features which seeks to be more like the face than the face itself: selected information is exaggerated, noise is reduced, and the processes involved in recognition are exploited. After studying the methods of caricaturists, examining perceptual phenomena regarding individuating features, and surveying automatic and man-machine systems which represent and manipulate the face, some heuristics for caricature are defined . An algorithm is implemented to amplify the nuance of a human face in a computer- generated caricature. This is done by comparing the face to a norm and then distorting the face even further away from that norm . Issues of style, context and animation are discussed. The applications of the caricature generator in the areas of teleconferencing, games, and interactive graphic interfaces are explored. / by Susan Elise Brennan. / M.S.V.S.
