The report summarizes work done in the study of measures for the effectiveness of the performance of large file systems. It consists of six sections: An "Introduction and Summary" which describes the background for the study, the approach taken in it, and summarizes the results; A discussion of the "Forms of Input", which characterizes the basic…

Project Intrex is a program of experiments intended to provide a foundation for the design of future information transfer systems, with the library of the future visualized as a computer-managed communications network. In order to discover the necessary facts, especially in the area of the user's interaction with the system, experimentation is…

This first of a four-volume series of reports summarizes the results of the MITRE Corporation's five years of technical, economic, and operational studies of interactive television. First reviewed are some major accomplishments such as: 1) the development of a new cable television (CATV) system configuration 2) the application for social services…

A system of computer-assisted data analysis (CADA) was developed at the University of Iowa to handle the mechanical, arithmetical and computational tasks associated with Bayesian statistical analysis. The original programs were subsequently expanded and a CADA monitor constructed to aid their use; a search was then undertaken to find a means of…

Increases in the cost of travel together with projected decreases in the cost of long distance telephone calls indicate that economy in consultation can be increased by a shift to more telephone consultation in the future. This may be difficult and awkward for researchers if consultation involves looking at computer output, particularly in an…

Human performance reliability for tasks in the time-space continuous domain is defined and a general mathematical model presented. The human performance measurement terms time-to-error and time-to-error-correction are defined. The model and measurement terms are tested using laboratory vigilance and manual control tasks. Error and error-correction…

The training requirements associated with equipment and systems utilized in underwater salvage operations and with the diving activities which are a part of underwater salvage operations are examined. The major emphasis of the study was on the training conditions suitable for the diver. It was found that divers are best trained in a tank or in…

This report presents a review and evaluation of three remote access on-line information retrieval systems and some ideas on what the capabilities of an ideal on-line information retrieval system should be. The three systems reviewed are the DDC Remote On-Line Retrieval System, the National Aeronautics and Space Administration RECON System, and the…

This paper explains DASM, a package of programs and routines for Direct Access Storage Management on 70/564 disc packs. Its basic unit of data is a record. DASM processes (retrieves and maintains) records by techniques which require the user to reference a record by its name (both record and file name). The steps through which a user can create a…

The results of the field trials of the Lincoln Training System (LTS-3) program are summarized in this report. The LTS-3 system was designed to teach basic electronics to Air Force personnel at Kessler Air Force Base, Mississippi. The results indicated that the instructional delays due to system failure were minimal, and those failures were…

The capabilities and possibilities of word processing and the degrees of skill required by word processing operators, supervisors, and executives are presented by a representative of a company offering training and recruitment services in word processing. (MF)

Describes the philosophy of intelligent instructional systems and presents an example of such a system, BLOCKS. The notion of BLOCKS as a paradigmatic system is explicated from both the system development and educational points of view. (Author/VT)

Survey of the history and current development of information technology covers hardware (economies of scale, communications technology, magnetic and optical forms of storage), and the evolution of systems software ("tool" software, applications software, and nonprocedural languages). The effect of new computer technologies on human…

The author discusses how to use a sociotechnical systems approach when implementing technology in the workplace to ensure better acceptance of technology and increased effectiveness of the new systems. (CH)

Identifies human factor issues involved in the student-computer interface in computer assisted instruction and makes specific recommendations for screen design. Factors considered include simplicity, spaciousness, relevance, standardization, changing display screen contents, color coding, shape and size coding, and brightness coding. (Author/LRW)
