A common command language has been proposed for use by systems designers and those developing new user interfaces. There is controversy over the appropriateness of a standard command language, and those who are working in artificial intelligence believe that natural language interfaces will make it unnecessary for users to learn such a language,…

The automation of online order retrieval for Chemical Abstracts Service Document Delivery Service was accomplished by shifting to an order retrieval/dispatch process linked to a Unix network. The Unix-based environment, its terminal emulation, page-break, and user-friendly interface software, and later enhancements are reviewed. Resultant increase…

A consideration of the development of on-line systems in terms of the computer changes that made on-line searching possible, and the use of these changes by information retrieval systems. (Author/KP)

Describes a study that measured the speed, error rates, and subjective evaluation of arrow jump keys, a jump mouse, number keys, and a touch screen in an interactive encyclopedia. The results of previous studies are discussed as well as the findings of this study. Improvements in selection devices are suggested. (41 references) (Author/CLB)

Describes an interactive data retrieval system which was designed and implemented for casual users and which incorporates a user-friendly interface, aids to train beginners in use of the system, versatility in output, and error recovery protocols. A 14-item reference list and two figures illustrating system operation and output are included. (JL)

Comparison of the use in libraries of open systems--a configuration of software and hardware components from separate vendors linked by interfaces--and integrated systems considers selection of services; reliability; relationships with vendors; time needed to implement systems; and overall effectiveness of both approaches. (CLB)

An automated library routine management system was developed in-house to create system unique to the Library and Information Center, Lunar and Planetary Institute, Houston, Texas. A modular approach was used to allow continuity in operations and services as system was implemented. Acronyms and computer accounts and file names are appended.…

Overview of expert systems (intelligent computer applications that use data, a knowledge base, and a control mechanism to solve problems) highlights history of expert systems; construction (human element, knowledge acquisition and learning, system architecture); limitations; issues and trends; and implications for information science. Thirty-three…

Provides a brief overview of videotex systems currently in operation and discusses an analysis of those systems in which the various features of the videotex user-system interface were identified. System design considerations for videotex are outlined and the results of the feature analysis of existing systems are presented in three figures.…

Discusses reasons for the development of an online catalog using computer output microfiche (COM) supplements to the card catalog in a university library, and outlines some of the principles used in designing the online system. Three references are cited. (CHC)

This progress report covers a two-year project which is part of a program that is exploring the value of computer aids in augmenting human intellectual capability. The background and nature of the program, its resources, and the activities it has undertaken are outlined. User experience in applying augmentation tools and techniques to various…

Part of a sustained program that has involved the design of personally tailored information systems responsive to the needs of scientists performing common research and teaching tasks, this project focuses on the procedural and content requirements for accomplishing need diagnosis and presents these requirements as specifications for an…

After surveying the history and current status of online database searching, this report offers a timeline describing four stages of possible developments for online systems. In the first stage, an expert interface assists CD-ROM-based searching by offering advice about search strategies. Advantages are that search logic can be refined with the…

The document highlights in nontechnical language the development of the Defense Documentation Center (DDC) Remote On-Line Retrieval System from its inception in 1967 to what is planned. It describes in detail the current operating system, equipment configuration and associated costs, user training and system evaluation and may be of value to other…

Redesign of human-computer interface for users of computerized information systems can make substantial difference in training time, performance speed, error rates, and user satisfaction. Information and computer scientists are using controlled psychologically oriented experimentation, and evaluations during system development and active use to…
