This paper presents a framework for understanding the various roles and structures for computer graphics in group communication, and discusses three basic types of design decisions that need to be addressed in using such graphics systems: (1) How are the systems to be intergrated in the group communication activity? (2) How are the systems to be…

The revolution brought about by computerized technology, in general, and television imagery, in particular, challenges the perceptual habits and alters the television viewer's means of expressing appreciation of the aesthetic merits of such television images. This study speculates on several perceptual and aesthetic drawbacks of future massive…

This paper focuses on graphics and how they can be created, in real time, from information stored in a database, and the application of this technique to computer-assisted instruction (CAI). It is noted that this is a special case of the general trend towards endowing instructional systems with a degree of decision-making or design expertise, as…

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…

Over the past few years, video technology has been used to assist film directors after they have shot a scene, to control costs, and to create special effects, especially computer assisted graphics. At present, a computer based editing system called "Film 5" combines computer technology and video tape with film to save as much as 50% of…

Computer based instruction (CBI) is composed of individual frames viewed one at a time. Compared to a typical textbook, CBI restricts the adult learner's capacity to access information from different parts of the lesson and to view complex presentations. Designers of CBI must compensate for these limitations by making a concerted effort to…

In the last 10 years, an approach to electronic distance education called audiographic computerized telelearning using standard telephone lines has come to the fore. Telelearning is a cost-effective system which optimizes existing computer facilities and creates a teaching-learning environment that is interactive, efficient, and adaptable to a…

Although the use of animated visuals is both common and popular among computer based instruction (CBI) designers, the theoretical and empirical foundation for their use have not been firmly established. Animated visuals represent a subset of instructional visuals, not a distinctive set. For this reason, general conclusions from research on static…

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.…

Arguing that females need instruction in visuo-spatial skills before adolescence, when they begin to lag behind males in the development of these skills that are so strongly correlated with success in technical careers, this paper discusses the use of the three-dimensional and spherical graphics of ExperLOGO to develop spatial skills in students…

Instructional design considerations involved in using level four videodisc systems when designing simulations are explored. Discussion of the hardware and software system characteristics notes that computer based training offers the features of text, graphics, color, animation, and highlighting techniques, while a videodisc player offers all of…

This paper, presented at a symposium on computer-based instructional systems, discusses innovations in the TICCIT computer-based instructional system. Specific issues addressed include innovations in the system's authoring languages, integration of videodisc technology, instructional management systems, creation of color computer graphics using a…

This four-section paper begins with a brief description of videotex and the paths its development has followed during its short lifespan. The second section examines how videotex systems should present and display information, and how such information should be internally organized so that it is maximally useful for the reader/user. The analysis,…

A computer program written for the Apple II was designed to teach college students how to map expository information. The program consists of five lessons, the first beginning with a definition and illustration of mapping. In this introductory lesson, students are asked to answer three basic questions when reading expository text: identify the…

A few of the relationships between visual and verbal components are explored. Visuals are considered to be things that can be seen, visible things other than printed words that are used in a communication process. The term verbal applies to written or spoken words. The natural tendency for visual and verbal components to be mutually supportive has…
