This discussion of factors involved in the presentation of text, numeric data, and/or visuals using video display devices describes in some detail the following types of presentation: (1) visual displays, with attention to additive color combination; measurements, including luminance, radiance, brightness, and lightness; and standards, with…

Lists 27 suggestions for making cost-effective decisions when buying personal computers. Topics covered include physical comfort; modem speed; color graphics; institutional discounts; direct-order firms; brand names; replacing versus upgrading; expanding hard disk capacity; printers; software; wants versus needs; and RLIN (Research Libraries…

Discussion of online catalogs focuses on issues in interface design. Issues addressed include understanding the user base; common user access (CUA) with personal computers; common command language (CCL); hyperlinks; screen design issues; differences from card catalogs; indexes; graphic user interfaces (GUIs); color; online help; and remote users.…

This examination of the effectiveness of various methods of cuing users to their location in a videotex information system used five different versions of an electronic edition of a college catalog: "simple" (no cues), "headers" (textual cues), "color" (color cues), "icons" (graphic cues), and…

The relative effectiveness of digital versus photographic images was examined with 96 college students as subjects. A 2x2 balanced factorial design was employed to test eight hypotheses. The four groups were (1) digitized black and white; (2) digitized pseudocolor; (3) photographic black and white; and (4) photographic realistic color. Findings…

This paper examines the benefits of a metaphorical graphical user interface (GUI) and discusses how metaphorical interfaces can be used to deliver instruction on stress management. A computer-based instructional (CBI) program for college students was developed on the fundamentals of stress and the role of time management as a coping strategy. The…

A gender gap between boys and girls has been reported in computer usage. Graphics may play a role in bridging that gap because of their motivational value. The literature reports gender differences regarding graphic content, color, detail, size, and movement. Based on these findings, preliminary design guidelines for graphics in computer-based…

This study investigates whether color and background information in motion visuals have different effects on memory and comprehension of students in various grade levels. A three-by-three factorial pretest-posttest design was used, comparing levels of visual complexity and grade levels. The instructional content was a 12-minute computer animation…

This study describes preschoolers' computer-generated graphics. Of specific interest were three questions: (1) What is the nature of children's computer-generated drawings in terms of the developmental stages of art? (2) How do the stages evident in children's computer-generated drawings compare with those in drawings produced with traditional art…

The role of color used in graphics in facilitating recall of verbal material was studied in a follow-up to previous research on the use of a color code in graphics presentations. An analysis of variance for repeated measures was used to test the hypothesis that significant interactions and differences would occur. Independent variables manipulated…

Screen designers for computer-mediated instruction (CMI) products must consider the motivational appeal of their designs. Although learners may be motivated to use CMI programs initially because of their novelty, this effect wears off and the instruction must stand on its own. Instructional screens must provide effective and efficient instruction,…

A study was conducted to investigate the comprehensibility of microcomputer-generated color graphics that are displayed on monochromatic monitors. Subjects were 64 second, third, and fourth graders who were randomly assigned to one of two conditions. Children in the first treatment were asked to identify, on a monochrome monitor, a figure that was…

The way information is visually designed and synthesized greatly affects how people understand and use that information. Increased use of the World Wide Web as a teaching tool makes it imperative to question how visual/verbal information presented via the Web can increase or restrict understanding. The purpose of this study was to examine…

Explores children's systems of combining drawing, talk, and writing (i.e., symbol-weaving) with traditional media and with new information technology. Social aspects of writing are discussed, and new information technology is examined, including clip art software, word processing, graphics, color, hypermedia, CD-ROM, and microworlds. (23…
