Describes "builds" and "filters," two simple forms to interactive media that the viewer can control to reveal new layers of information and that often save resources by replacing many separate graphics. (SR)

Describes an inexpensive solution to the problem of transferring pictures onto a television screen using the analog part of the Model "B" BBC Microcomputer. Instruction for building the graphics tablet (which can easily be constructed by secondary students), program listing for required software, and documentation are included. (JN)

Suggests that the way desktop computers are used in business communication will change dramatically with the emergence of DVI (Digital Video Interactive) technology and modern mass storage devices. Discusses implications of DVI for business communication educators and trainers. (RS)

Interactive computer graphics is fast becoming the standard medium of communication between computers and all kinds of users. Reasons for this trend, the technology of interactive graphics displays, software considerations, applications (including classroom and laboratory applications), and future developments are discussed. (JN)

Relates experiences of an elementary school reading teacher and a group of fifth- and sixth-grade students in exploring the computer programing language Logo. Use of a tree-like figure as an illustration for the concept of recursion is described. Programing commands and graphic illustrations are included. (EJS)

Presents a programing subroutine which will create a graphical plot that occupies any number of columns specified by user and will run with versions of BASIC programming language. Illustrations of the subroutine's ability to operate successfully for three possibilities (negative values, positive values, and both positive and negative values) are…

Describes the uses of Lotus 1-2-3 (a spreadsheet-graphics-database program created by Lotus Development Corporation) and Symphony 1.1 (a refinement and expansion of Symphony 1.01 providing memory efficiency, speed, ease of use, greater file compatibility). Spreadsheet and graphics capabilities, the use of windows, database environment, and…

Comparison of dot matrix impact printers details price, matrix density, speed, print sizes, feed width, interface connectors, and true descender characteristics. Dot matrix versus preformed characters, maintenance and repair, installing printers at microcomputer workstations, value comparisons, and descriptions of specific printers are…

An evaluation of a personal computer was conducted to determine its potential for applications normally assumed to require higher resolution, higher cost graphics devices. Its resolution, stand-alone computing power, and capability to function as a distributed computing element in a time-sharing system are discussed. Six references are listed.…

Provides the rationale for considering communication in a graphic domain and suggests a specific goal for designing work stations which provide graphic capabilities in educational settings. The central element of this recommendation is the "pictorial conversation", a highly interactive exchange that includes pictures as the central elements.…

Provides a brief discussion of the graphics capabilities of microcomputers and describes specific graphics hardware and software that are available for the more popular microcomputers. The names and addresses of the producer/distributor and prices are given for each item. (CHC)

Provides recommendations for designing computer screens that will have positive effects on readability and learning. Topics discussed include the use of capital versus lower case letters; interlinear space; line length; and strategies that aid recall, including the use of chunks and margins, and the location of information in relation to graphics.…

Discusses a presentation prepared by Boeing Computer Services in cooperation with the Tacoma Public Library staff, which demonstrates the potential of interactive cable systems based on the Canadian Telidon system. Features of this videotex system, software, and equipment, including microcomputers, are noted. (EJS)

Provides guidelines for designing television screen displays, including format (material on one screen - no scrolling, screen readable, variety in layout, eye movement considered) and visual imagery (organization consistent with message, pictures added to enhance image, movement/animation used with discretion, and others). Also provides rationale…

Provides insight into technique for developing 3-dimensional computer graphics for use in artistic expression, design of functional objects, and the development of frame-by-frame computer animated films. Objects defined by intersecting spheres, hardware, software, examples, and illustrations are included. Twenty-four references are cited. (EJS)
