A Comparative Evaluation of Graphical User Interfaces BIBA 12-15
  Rainer Ebner; Gunter Haring; Franz Penz; Gerhard Weichselberger
In a study based on a questionnaire and an empirical test three graphical user interfaces for the DOS operating system commands (GEM, Windows 1.04, Windows 2.01) are compared.
Human-Computer Interaction: An Operational Definition BIBAK 16-22
  Shaun Marsh
This paper poses an operational definition for the term Human-Computer Interaction and distinguishes it from the term User Interface, Human-Computer Interaction includes several separate communication paths between the human and the computer's natural environment, the computer's own ergonomics, an operating environment, and an application environment. Each of these paths occur in parallel and have both a dialog and an interface component. A distinction is made between those dialog stages which allow multiple interpretations of symbols (soft-dialog) and those which allow only one interpretation for each symbol (hard-dialog). The term User Dialog includes only the soft dialog stages, and the User Interface consists of the mechanisms for communicating the User Dialog.
Keywords: Human-computer interaction, User interface

Using Graphs to Explore Databases and Create Reports BIBA 24-27
  Robert Barr
In most information systems that use them, graphs "illustrate" the numbers in a crosstab- or list-style report. However, they can also be employed both to explore a database to locate wanted data, and to retrieve data from the database to create a report.
Interface Design as a Prosthesis for an Individual with a Brain Injury BIBA 28-32
  Elliot Cole; Parto Dehdashti
This is a case study demonstrating how interface design was applied to make personal productivity software accessible and appropriate for an individual with learning disabilities from a head injury. Substantial customization was required, and nine months of data are presented.
User Models of the Circuit Design Process BIBA 33-35
  Lynne Colgan; Paul Rankin; Maddy Brouwer-Janse
To aid in the design of both a CAD system and its user interface, studies of circuit designers using a prototyped system resulted in several user model diagrams depicting the analogue circuit design process. The relative merits of this approach and its effect on the system design are discussed.
A Graphical User Interface to Support a Production Team BIBA 36-39
  Stephen M. DiPietro
This paper describes the user interface of a software system that supports production of a large geographic database. The user interface of the system facilitates coordination of a production team whose activities are separated in time and space. The user interface provides visibility into the status and organization of the production effort and provides easy access to the tools and data required to perform the work.

Bringing Natural Language Information Retrieval Out of the Closet BIBA 42-48
  Donna Harman; Gerald Candela
A prototype information retrieval system was developed that gives users fast and easy access to textual information. This system uses a statistical ranking methodology that allows a user to input a query using only natural language, such as a sentence or a noun phrase, with no special syntax required. The system returns a set of text titles or descriptions, ranked in order of likely relevance to query. The user can then select one or more titles for further examination of the corresponding text. The prototype was tested by over forty users, all proficient in doing manual research in the subject area, but few proficient in doing online research. The system was very fast, providing response times on the order of one second for searching a gigabyte of data and was also very effective, retrieving at least one relevant record within the first ten records retrieved for 53 out of 68 test queries. All users were able to get satisfactory results within a short time after seeing a demonstration, and those that had never used an online retrieval system did as well as those with experience. This is in sharp contrast to Boolean based retrieval systems where continual use is necessary to obtain consistently good results.

Teaching User Interface Development to Software Engineering and Computer Science Majors BIBA 61-66
  Gary Perlman
There is a critical need for timely and usable curriculum development materials for teaching user interface development to software engineering and computer science students. An updated version of the Software Engineering Institute's curriculum module on User Interface Development has been released. This paper provides an overview of the module, its history, and how it has been used.
   At the Software Engineering Institute (SEI) at Carnegie Mellon University there is a Curriculum Development Project as part of the Education Program (Gibbs, 1989). A major goal of the curriculum development project is to devise model curricula and support-materials for teaching all topics in software engineering. For topics such as unit testing, software design, requirements analysis, and so on, there are curriculum modules to help teachers prepare courses. I have written, and recently revised, a module on User Interface Development (Perlman, 1989b), described in detail below. It has proven to be useful to all people interested in the teaching of user interface development to software engineers. Some of my experiences with the module are summarized in Perlman (1988).
   The module is not a book nor a course, but contains information to help others prepare short- or full-term courses on user interface development.
Key Issues in HCI Curriculum Design BIBA 67-69
  Jenny Preece; Laurie Keller
This paper reports on key issues that needed to be resolved in developing a large postgraduate distance education course in human-computer interaction intended for practicing software developers and technical managers.
   The multi-disciplinary nature of HCI is identified as being highly controversial when deciding what to teach and how. Questions about the balance of theory versus practice and providing tools versus knowledge are also considered major issues. A less general set of issues including questions such as what is design are also considered. Here, many of the sources of controversy can be traced to higher level issues, in particular the multi-disciplinary nature of HCI.
An Iconic Description Language: Programming Support for Data Structure Visualization BIBAK 70-72
  Kudang B. Seminar; Robert N. Robson
An icon description language, named DSIL (Data Structure Iconic Language), is described which facilitates the design of icons depicting data structures and accelerates the development of iconic interfacing tools for program visualization and debugging. By using the DSIL, different users can define or redefine their own icons to satisfy their needs. The DSIL has features of modern programming languages. It is hierarchical, modular, and provides adoption (inheritance). The design of the DSIL is based on the features of data structures in MODULA-2. The implementation of the DSIL in a data structure editor is presented.

Design Process and Decision Rationale Models for the N-Chime Interface System BIBA 73-79
  Siegfried Treu; D. Peter Sanderson; Roman Rozin; Ravi Sharma
The N-CHIME interface system was designed with the broad objective of enabling, or "empowering," different types of users to carry out effective modeling and simulation applications with the Hierarchical Simulation Language (HSL). A design methodology was developed that is based on a "parallel processes" model: a triad of parallel design processes, one directed at each of the user, the interface and the application. For comprehensive and systematic interface design, such a methodology is essential. N-CHIME has been implemented and tested. This paper presents an overview of the design models and some of the resulting tools and techniques supportive of the application-specific user. It also highlights the importance of providing online access to the design decision rationales that were used for the various user-visible tools and devices.

Group HCI Design: Problems and Prospects BIBA 37-41
  Bernard J. Catterall; Susan Harker; Gary Klein; Mark Notess; John C. Tang
Design of human-computer interfaces is typically carried out by groups of designers rather than by isolated individuals. In this report, we characterize those groups and their contexts, examine the problems that such groups encounter, and evaluate the extent to which current HCI techniques address the needs of groups of designers.

Workshop Report

The Universe of Design is Unfolding (As It Should!) BIBA 46-48
  Jim Carter
This is a brief report of the discussion in one of the subgroups from the "Taking Design Seriously" Workshop at CHI'90. The "Cosmic Glue" subgroup organized around the concept that there needs to be something at a higher level than the "Design Process(es) of HCI". This higher "Cosmic Glue" should lead towards systems that actually (rather than only theoretically) satisfy their users and their purposes for being.
