This material is intended as a programmer's reference for the software package contained in the MTS file K033:CKLIB for use with a Computek terminal. It is assumed that the reader is familiar with FORTRAN programing in MTS and is acquainted with the Computek terminal. (MK)

The Graphic Terminal Display System (GTDS) was created to support research and development in computer-assisted instruction (CAI). The system uses an IBM 360/50 computer and interfaces with a large-screen graphics display terminal, a random-access slide projector, and a speech synthesizer. An authoring language, GRAIL, was developed for CAI, and…

The interactive system for creating graphic displays that is described is presented as one solution to the problem created by the lack of complementary firmware or software to make the graphic capabilities of many current terminals easily accessible to the instructional programmer. The use of this system by the Digital Equipment Corporation's…

An electronics graphic symbol set for on-line construction of electrical and electronics schematic diagrams is described. Specific procedures involving off-line and on-line activities are presented for the development and entry of schematic diagrams utilizing a stored set of symbols. An example of the commands and coding required for the…

Two different uses of interactive graphics in computer-assisted instruction are described. Interactive graphics may be used as substitutes for physical devices and operations. An example is simulation of operating on man/machine interfaces, substituting interactive graphics for controls, indicators, and indications. Interactive graphics may also…

This is a report of a program aimed at the demonstration, tests, and evaluation of the educational and economic effectiveness of PLATO IV computer-based education as implemented in several geographically dispersed military training sites. It also describes a technical program aimed at increasing the cost effectiveness of the PLATO system. During…

Many of the costs of design, construction, and building operation derive from the reliance on drawings as the description of record of the building. As a replacement, this paper outlines the design of a computer system useful for storing and manipulating design information at a detail allowing design, construction, and operational analysis. A…

Computer graphics systems typically produce a single, machine-like character font. At most, these systems enable the user to (1) alter the aspect ratio (height-to-width ratio) of the characters, (2) specify a transformation matrix to slant the characters, and (3) define a virtual pen table to change the lineweight of the plotted characters.…

The application of artificial intelligence (AI) techniques to the design of personal learning environments is an enterprise of both theoretical and practical interest. In the short term, the process of developing and testing intelligent tutoring programs serves as a new experimental vehicle for exploring alternative cognitive and pedagogical…

Development of the Building Description System (BDS) was undertaken to explore use of the computer to construct models of complex physical systems. A fundamental goal of this work is a computer system capable of replacing drawings as the primary description for design and construction of buildings. This paper presents an overview of the database…

The Air Force has been plagued with the rising cost of technical training and has increasingly turned to computer-assisted instruction (CAI) for better cost effectiveness. Toward this aim a trial of PLATO IV, a CAI system utilizing a graphic display and centered at the University of Illinois, was initiated at the Chanute and Sheppard training…

A low cost communications network has been designed for use in the PLATO IV computer-assisted instruction system. Over 1,000 remote computer graphic terminals each requiring a 1200 bps channel are to be connected to one centrally located computer. Digital data are distributed to these terminals using standard commercial cable television (CATV)…

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…
