Abstract

Reports on a continuing project to study children's use of a graphically-based direct manipulation interface for science materials. The Science Library Catalogue (SLC), a component of project SEED, has been implemented in the libraries of 21 elementary schools in Los Angeles and will soon be implemented in a public library. The interface employs a hierarchical structure drawn from the DDC and implemented in HyperCard on the Macintosh. The study on the 2nd version of the interface indicates that children are able to use the Science Library Catalogue unaided, with reasonable success in finding items. Search success on the same topics on a Boolean command driven system was equivalent, but Boolean searches were faster. However, the Boolean system was more sensitive to differences in age, with 12-year-olds having significantly better success rates than 10-year-olds; and to search topic, with one set of questions being much easier to search than the other. On average, children liked the 2 systems about the same; the Boolean system was more attractive to certain age and gender combinations, while the Science Library Catalogue was more consistently liked across groups. results are compared to prior studies on the Science Library Catalogue and other online catalogues

Abstract

Outlines the progress of HyperLib, research which began in 1993 to develop a hypertext interface to the online catalogue and other databases at the University of Antwerp. A human factors oriented design methodology was adopted. A user survey was carried out. The project has focused on development of electronic guides and manual and interfaces to access an academic bibliography database and the UDC subject classification scheme. Evaluation is being carried out in 1995

Abstract

Project Jefferson was designed to help new students at the University of Southern California (USC) to acquire skills necessary for writing research papers through the example of research into ethical issues raised by the US Constitution. It runs on Macintosh Computers and is based on Apple Computer's HyperCard, a system wich allows users to browse different sources of information at their own pace and along their own routes while noting down useful discoveries in the notebook part of the system. Access to USC's locally mounted bibliographic data bases is also given without any tedious logging-on routines.

Abstract

Presents the preliminary results of a pilot research project on disorientation in hypertextual educational systems. It explores spatial cognition's correlation with hypermedia navigation. Analyzes mental models, in order to justify their use as a basis for interface design. Introduces the notion of disorientation in a hypermedia environment. Illustrates the co-ordinates of experiments set up to verify the assumption that users need to build some form of conceptual representation of devices they are interacting with in order to understand them, and reports the results. Redefines the notions of spatial metaphor and of maps in the light of the results

Abstract

Hypertext for multi-media and full-text documents is rapidly developed on all fronts. For bibliographic information retrieval the applications are promising but pose several difficulties. Describes work conducted at the School of Library and Information Science at Univ. of Western Ontario the objective of which is to add the capability of a browsing search to an existing OPAC through the use of Windowed Hypertext Interface for Zippy Retrieval and Display (WHIZRD) software. Discusses the underlying retrieval capabilities of the system. Examines design problems and solutions and outlines future enhancements
