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…

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.…

This paper presents a study on the effects of various data compression methods from the viewpoint of central computer to terminal communications on a large graphics oriented timesharing system, PLATO IV. The desired goal is to increase terminal display speed without significant increase in the transmission error rates. While the major emphasis in…

This report describes SpaceGraph, a new computer-driven display technology capable of showing space-filling images, i.e., true three dimensional displays, and discusses the advantages of this technology over flat displays for use with the instructor/operator station (IOS) of a flight simulator. Ideas resulting from 17 brainstorming sessions with…

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…

Describes modifications made to expand the capabilities of a display unit (Lear Siegler ADM-3A) to include medium resolution graphics. The modifying circuitry is detailed along with software subroutined written in Z-80 machine language for controlling the video display. (JN)

The development and capabilities of an interactive preprocessor program with graphics for an existing three-dimensional finite element code is presented. This preprocessor program, EDGAP3D, is designed to be used in conjunction with the Texas Three Dimensional Grain Analysis Program (TXCAP3D). The code presented in this research is capable of the…

General principles of computer graphics are reviewed, including discussions of display hardware, geometric modeling, algorithms, and applications in science, computer-aided design, flight training, communications, business, art, and entertainment. (JN)

Addresses key issues facing universities which plan to establish instructional computer graphics facilities, including computer-aided design/computer aided manufacturing systems, role in curriculum, hardware, software, writing instructional software, faculty involvement, operations, and research. Thirty-seven references and two appendices are…

Discusses attributes which are offered as set of standards to judge instructional software--those unique to design of microcomputer courseware and those included in design of all instruction. Curriculum role, modes of interaction, computer managed instruction, graphics, feedback, packaging, and manuals are noted. Fourteen references are included.…

Design theory should identify candidate designers, specify design behavior to be measured, and discriminate between behavior of designers and nondesigners. A study evaluated different formats of computerized structural display and data entry to measure design behavior. A program using graph theory as an internal data structure in the computer and…

Large print/enhanced image computer access products for low-vision individuals are reviewed. The products ("DP-11/Plus,""Large Print DOS,""Lyon Large Print,""PC Lens,""Vista/Vista 2," and "ZoomText") work interactively with most application programs and DOS in IBM environments. Features…

This article describes differences between the graphical user interface and traditional character-based interface systems, identifies potential problems posed by graphic computing environments for blind computer users, and describes some programs and strategies that are being developed to provide access to those environments. (Author/JDD)

Compiled are ten papers describing computer hardware and computer use in elementary and secondary school instruction presented at the Association for Educational Data Systems (AEDS) 1976 convention. An oral/aural terminal is described followed by two papers about the use of minicomputers and microprocessors. Seven papers discuss various uses of…

The image generator function and author language software support for the CHARGE (Color Halftone Area Graphics Environment) Interactive Graphics System are described. Designed initially for use in computer-assisted instruction (CAI) systems, the CHARGE Interactive Graphics System can provide graphic displays for various applications including…
