- 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
- Explores the hypothesis that using a zooming graphical interface minimizes user disorientation when reading documents in an electronic environment. 36 graduate students at the University of Maryland at College Park, USA, were randomly assigned to read a hypertext document in either Pad++, a zooming graphical interface, or Mosaic, a jump-based interface. Questionnaires, observation, and taped interviews were used to compare and evalutae the use of the 2 interfaces with regard to learning time, performance and user satisfaction. Findings suggest as workstations become more powerful, a hybrid interface that adds continuous zooming to the existing mechanisms of scroll, pan and jump will emerge

- 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 systems provide an appealing mechanism for informally browsing databases by traversing selectable links. However, in many fact finding situations string searching is an effective complement to browsing. Describes the application of the signature file method to achieve rapid and convenient strung search in small personal computer hypertext environments. The method has been implemented to a prototype, as well as in a commercial product. Presents performance data for search times and storage space from a commercial hypertext database and discusses user interface issues. Experience with the string search interface indicates that it was used successfully by novice users

- 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
- Librarians find themselves today in a lively period of the evolution of user interfaces to online information. Most of the newer interfaces incorporate graphics, colour and mouse-supported searching to make intiation for the novics user easier and all searching more productive. Describes the University of Delaware's development of DELCAT MacPAC, a HyperCard-based front-end to the university's OPAC, adapted from Cornell University's MacPAC. The focus is on Delaware's customisation of MacPAC for its environment, including the support of remote users, and the testing, use, and distribution of the product

- 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

- 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
- Proposes a model for integrating hypermedia and expert systems and describes an implementation. The proposed model consists of an expert system with a hypermedia user interface module and hypermedia output explanation module. Describes implementation based on the proposed model, and expert system named the Tourist Hyper-Expert Consultant (THECO). The results showed that the proposed model and structure, which employ hypermedia features, can enhance the user interface and output explanation modules of expert systems. Incorporating hypermedia into the user interface module enhances the flexibility of the expert system application in acquiring inputs from the users. Hypermedia also improved the ability of the output explanation module to give more comprehensive recommendations
