Presents a group of semiotic principles for software design and uses them to show how they explain different educational possibilities. Discusses interface design and describes Theater in the Computer, a software environment for children, to illustrate semiotic-based principle of interface design. (Author/LRW)

This paper discusses a generic query tool that enables an end user to query a metadata store through filters that impose search criteria on attributes. The Metadata Query Tool (MQT) is generic in the sense that it dynamically creates its user interface, based on configuration files that define the metadata scheme and the query functionalities.…

Discusses a user interface that simplifies NF Squared (non-first-normal-form) relational query formulation in which query specification remains compact and straightforward. This interface allows for nesting and general hierarchical structures and restructuring which provides for more effective retrieval and query formulation. (Author/JKP)

To support performance for an international audience of computer users, designers need to examine key elements of performance in relation to the design of systems. Discussion focuses on planning ahead for an international audience and preparing a design that keeps the performer, the process, and the information connected, resulting in optimal…

Various schools are struggling with the introduction of Object Oriented (OO) programming concepts and GUI (graphical user interfaces) within the traditional COBOL sequence. OO programming has been introduced in some of the curricula with languages such as C++, Smalltalk, and Java. Introducing OO programming into a typical COBOL sequence presents…

Discussion of information systems methodologies that can contribute to interface design for public access systems covers: the systems life cycle; advantages of adopting information systems methodologies; soft systems methodologies; task-oriented approaches to user interface design; holistic design, the Star model, and prototyping; the…

Performance Centered Design (PCD) offers an alternative to the old methodology of software development. The author suggests one design possibility that could be used to create a more universally satisfying interface for existing applications, an adaptive mini-program that "sits" between the larger application and the user. Potential…

Information systems (IS) professionals are called on to produce increasingly sophisticated user interfaces as a part of software development. Although IS education includes coverage of user interface (UI) development, classroom presentation of this topic frequently is cursory and does not provide any particular methodology for the task. In this…

Reviews the literature on the design and evaluation of user interfaces on CD-ROM. Defines interfaces, dialogs and interaction and explores diversity in, and issues associated with, standardization in interface design for CD-ROMs. Reviews current criteria and guidelines for the evaluation of CD-ROM interfaces and proposes alternative guidelines.…

This paper describes the design of a synchronous World Wide Web-based distance education environment developed at the Telematics Laboratory of Computer Engineer and Informatics Department (CEID) and Computer Technology Institute (Greece); the environment uses telematics services to conduct lessons over computer networks, simulating a traditional…

This paper reports on considerations about the common basic functions and components for building a collaborative authoring environment. The paper aims to specify and systematize the technological issues towards the future standardization of such environments, based on the authors' previous research experiences. Standardization includes many…

As computing and embedded systems become ubiquitous in our world, the importance of user interface design knowledge increases in our curriculum. Students of undergraduate information systems or computer science programs should possess some competence in this computing sub-discipline. However, many programs do not have the curricular space to host…

This paper describes the IFLA (International Federation of Library Associations and Institutions) guidelines for librarians charged with customizing OPAC (online public access catalog) software and vendors and producers of this software. The guidelines are intended to apply to all types of catalog, including World Wide Web-based catalogs, GUI…

E-Referencer is an expert intermediary system for searching library online public access catalogs (OPACs) on the World Wide Web. It is implemented as a proxy server that mediates the interaction between the user and Boolean OPACs. It transforms a Boolean OPAC into a retrieval system with many of the search capabilities of Web search engines.…

Viewing high-resolution images on the World Wide Web at a level of detail necessary for collaborative research is still a problem today, given the Internet's current bandwidth limitations and its ever increasing network traffic. ImageEyes is an interactive display tool being developed at Utah State University that addresses this problem by…
