In recent years, software operating skills, the ability in computer literacy to solve problems using specific software, has become much more important. A great deal of research has also proven that students' software operating skills can be efficiently improved by practicing customized virtual and simulated examinations. However, constructing…

In the current object-oriented paradigm, software construction increasingly involves creating and utilizing "software components". These components can serve a variety of functions, from common algorithmic processes to database connectivity to graphical interfaces. The advantage of component architectures is that programmers can use pre-existing…

Information systems increasingly provide options for visually inspecting data during the process of information discovery and exploration. Little research has dealt so far with user interactions with these systems, and specifically with the effects of characteristics of the displayed data and the user on performance with such systems. The study…

Describes the technical characteristics of Telidon, a second-generation videotex system developed in Canada and announced in August 1978, and discusses what has occurred since that time in planning field trials, developing information services, and in planning a coordinated development for Canada of this new technology. (Author)

Reviews five areas in which computer graphics technology has been applied: animation, computer-aided design, home information systems, scientific uses, and geographic information systems. (FM)

Academic libraries customize, support, and provide access to myriad information systems, each with complex graphical user interfaces. The number of possible information entry points on an academic library Web site is both daunting to the end-user and consistently challenging to library Web site designers. Faced with the challenges inherent in…

Describes significant attributes of expert systems, contrasts them to conventional computer systems, and provides an overview of the R1 expert system used by Digital Equipment Corporation (DEC) to put together operational systems that meet customers' requirements. Document handling, particularly pictures and images in documents, is also briefly…

This article illustrates how Lotus 1-2-3 software can be used to create graphs using downloaded online searches as raw material, notes most commands applied, and outlines three required steps: downloading, importing the downloading file into the worksheet, and making graphs. An example in bibliometrics and sample graphs are included. (EJS)

Finding information on the Web without encountering numerous false positives poses a challenge to multimedia information retrieval systems (MMIR). This research focuses on improving precision and recall in an MMIR system by interactively combining text processing with image processing in both the indexing and retrieval phases. A picture search…

Presents detailed guidelines based on the literature for screen layout and design of online catalogs, and discusses the potential advantages in terms of number of transactions per hour and user satisfaction. Further research questions are suggested and an extensive bibliography is provided. (CLB)

Describes capabilities and advantages of spreadsheet software, including its ability to perform "what-if" analysis quickly and easily. Also noted are additional advantages; applications, including use in the library environment; history and development; new-generation spreadsheets; and enhanced packaging in the near future. A spreadsheet…

Focuses on the multiple design issues involved in creating successful menu selection systems: semantic organization, response time, display rates, shortcuts for frequent users, titles, phrasing of menu items, graphic layout, and selection mechanisms. Pop-up and embedded menus, experimental results, and design guidelines are also covered.…

In personal information retrieval, items are associated with events and can be accessed by their relationship to events as well as content. Describes two early projects and a prototype graphical event-based retrieval system comprising file changes, mail messages, active badge sightings, video snapshots, desk diary entries, notes, weather reports…

Discusses how simulation technology for the analysis of information systems (IS) supports human decision making. Examines online help and knowledge-based support, graphics, and visual interactive simulation (VIS) and animation. Concludes that there are opportunities to improve the decision support role of simulation technology in IS with enhanced…

Discusses new possibilities that computers and laser printers offer instructional technologists. Includes a brief history of printed communications, a description of new technological advances referred to as "desktop publishing," and suggests the application of this technology to instructional tasks.
