As intelligent systems demand for human-automation interaction increases, the need for learners' cognitive traits adaptation in adaptive educational hypermedia systems (AEHS) has dramatically increased. AEHS utilize learners' cognitive processes to attain fair human-automation interaction for their adaptive processes. However, obtaining accurate…

We applied a user interface (UI) design approach based on a constructivist perspective for web-based learning that conceptualizes interactions between learners and websites as conversations. Hyperlinks on the UI of a distributed interactive learning environment were treated as invitations for interaction to encourage learners' active exploration.…

Link recommendation, which suggests links to connect currently unlinked users, is a key functionality offered by major online social networking platforms. Salient examples of link recommendation include "people you may know"' on Facebook and "who to follow" on Twitter. A social networking platform has two types of stakeholder:…

Critically reviews the different types of abstractions and implementations in the area of hypertext and proposes the existence of three types of hypertext: small, medium, and large volume. Each type of hypertext is described, human-computer interaction is considered, and a movement toward intelligent hypertext is discussed. (48 references) (LRW)

Interactive computer simulations with complex representations and sophisticated graphics are a relatively new addition to the classroom, and research in this area is limited. We have conducted over 200 individual student interviews during which the students described what they were thinking as they interacted with simulations. These interviews…

Presents an approach which can provide explanations to user questions in human-machine communication in a flexible way. To determine the contents of explanations, scripts are used which have different optional components organized according to the intentions of user questions to meet their information needs. (Author/LRW)

Focuses on methods of generating and evaluating hypertext. Highlights include historical landmarks; nonlinearity; literary hypertext; models of hypertext; manual, automatic, and semi-automatic generation of hypertext; mathematical models for hypertext evaluation, including computing coverage and correlation; human factors in evaluation; and…

Presents background information that describes the major components of an embedded performance support system, compares levels of functionality, and discusses some of the required technologies. Highlights include the human-computer interface; online help; advisors; training and tutoring; hypermedia; and artificial intelligence techniques. (LRW)

Discussion of human-computer interfaces focuses on the use of graphical and direct manipulation approaches to improve the user interface. Topics discussed include information seeking; computerized search capabilities, including full-text string searches, index searches, and hypertext; Boolean expressions; dynamic or direct manipulation queries;…

Discusses effective communication with interactive video and suggests possible barriers. Topics addressed include identifying the user; the need for standards; algorithms; the rapid development of hardware; navigation in interactive media; and interactivity with the user. (LRW)

Describes the development of a demonstration prototype Research Reference Interface (RRI) that was designed to assist novice instructional designers in justifying the instructional decisions of knowledge-based instructional design tools such as expert systems, decision support tools, intelligent job aids, and hypertext systems. Additional…

Proposes a conceptual reference architecture for information retrieval systems and discusses functional capabilities of a hypertext environment, based on the proposed architecture, for interaction with large textual databases. Functions of the prototype system HYPERLINE are described, and an example of a user session is provided. (17 references)…

Presents an information systems navigation approach using a combination of functionalities encountered in classification processes, Hypertext systems, and information retrieval systems. The first version of the SYRIUS system is described, with emphasis on the user's graphic interface which integrates these functionalities. (26 references) (EA)

Introduces a hypertext data model for textual databases in which the text is divided into a syntactic structure, which describes the relationships of the text parts, and an access structure, which is generated from the syntactic structure by users' queries. Implementation considerations for the structuring component, retrieval component, and…

Describes the design of an experimental computer-aided cataloging advisor, Mapper, that was developed to help novice users with the descriptive cataloging of single-sheet maps from U.S. publishers. The human-computer interface is considered, the use of HyperCard is discussed, the knowledge base is explained, and assistance screens are described.…
