The role pictures and graphics can play in making Telidon, a Canadian home information retrieval videotex service, a viable communications medium is discussed. This report concentrates on contributions of theories of perception and cognition to knowledge of how different kinds of visual images can most effectively be used on Telidon. The issues of…

Reviews the history of Telidon, the Canadian videotex system; describes Telidon's alphageometric method of graphic-information encoding; discusses some experimental applications of the Telidon system; and describes attempts at developing a North American standard for videotex systems. Five figures are included. (JL)

Describes an experiment which linked the Canadian Videotex development, TELIDON, with the Canadian CAL system based on the course author/programming language NATAL. A bibliography of 14 references is provided. (CHC)

Some of the major trends in the merging of videotex and personal computer technology are outlined in this promotional brochure, one of 10 in a series on videotex, a system which uses standard transmission links to transmit information in text and graphics to a television set or computer monitor. Topics addressed include the NAPLPS standard (North…

Discusses the possible futures of telecommunications and interactive television and describes the Internet and services now available through it. Topics addressed include access to the Internet; resources available; access costs; user-friendly graphical interfaces; the digital video channel, used for videoconferencing and experimental projects;…

This promotional brochure, one of 10 in a series on videotex, explains applications of videotex and the North American Presentation Level Protocol Syntax (NAPLPS) standard system (known as Telidon in Canada) for creating, storing, and transmitting text and color graphics information on a television screen or computer terminal. The specific…

Reviews the current status of satellite remote sensing data, including problems with efficient storage and rapid retrieval of the data, and appropriate computer graphics to process images. Areas of research concerned with overcoming these problems are described. (16 references) (CLB)

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,…

Abstracts of 23 papers given at the conference are presented. These deal with a variety of subjects related to educational uses of computers, including: 1) information networking, 2) computer-managed test item banks, 3) learner-controlled instruction and courseware, 4) computer-assisted instructional (CAI) systems such as Coursewriter III and…

Describes an application-specific hypertext system designed to facilitate and capture policy and design discussions. The discussion includes an introduction to the Issue Based Information Systems (IBIS) method; a description of this graphical IBIS (gIBIS) tool; an example of a gIBIS interaction; and thoughts about future research. (13 references)…

Recounts experiences of the Carbon Dioxide Information Center, a technical information analysis center at the Oak Ridge National Laboratory, which has utilized a microcomputer for exchange of automated bibliographic references. Procedures and problems in adding microcomputer information to mainframe databases are noted and other microcomputer…

One in a series of 10 promotional publications on videotex, this document describes both videotex and teletext and illustrates with actual examples how educators are using these new tools. Topics discussed include the educational roles permitted by the standardization of videotex and teletext; characteristics of the North American Presentation…

Describes systems which use wireless terminals to communicate with mainframe computers or minicomputers via radio band, discusses their limitations, and gives examples of networks using such systems. The use of communications satellites to increase their range and the possibility of using light beams to transmit data are also discussed. (MBR)

Follows the development of hypertext which is the electronic movement of large amounts of text. Probes the use of the Macintosh HyperCard and its applications in education. Notes programs are stackable in the computer. Provides tool, resource, and stack directory along with tips for using HyperCard. (MVL)

Describes the latest modifications being made to OASIS, a front-end enhancement to the University of California's MELVYL online union catalog. Highlights include the X Windows interface; multiple database searching to act as an information network; Lisp implementation for flexible data representation; and OASIS commands and features to help…
