We are so used to accept new technologies being the driver of change and innovation in human computer interfaces (HCI). In our research we focus on the development of innovations as a design process--or design, for short. We also refer to the entire process of creating innovations and putting them to use as "cognitive processes"--or…

This summary of issues addressed at the conference identifies 10 important themes: (1) the nature of interactivity, and whether linear presentations are obsolete; (2) what can be done with all the imagery made possible with videodisks and the sounds enabled by compact disks, and whether any of this is really new; (3) whether emotional…

An adaptation technique of multimodal interfaces based on a cognitive modeling of users is presented in this paper. The adaptation process tries to select a combination of modalities that best fits the cognitive profile of each user. This profile contains indicators of cognitive abilities and styles. This paper focuses on output modalities and…

This research begins to refine a cognitive model of interactive information seeking for use in the design of information retrieval (IR) systems. The research reported in this paper critically examines several interactive information seeking and retrieval models that have emerged over the last two decades. Building primarily on the stratified…

This report begins by discussing the implications of a constructivist epistemology for instructional design and development, as well as drawbacks of the content database in instruction, the lack of special tools to help the learner actively construct knowledge, and emphasis on learning environments based on individual learning. The whole learning…

This document presents a theoretical approach and a methodology for analyzing data from students interacting with and learning from hypermedia systems. Interactions are mutually influenced by individual students' goals and strategies and the actions supported by the interface of the learning environment. The approach is illustrated by modelling…

Explores the utility of the intersection of genre theory and cognitive psychology in providing a meaningful framework for analysis and design purposes. Reports results of research into the elements of genre that influence users of digital documents and provides examples of the usefulness of this analysis in Web-based environments. (Author/AEF)

Work in the design and construction of virtual environments (VEs) is described from the standpoint of semiotic theory. It is advocated that well-constructed visual worlds can create in a person the feelings and cognitions that arise from being in the natural world and that interactions with computer-constructed VEs are mediated through signs. The…

As a person learns, his problem solving ability improves and one reason for this is the increased acquisition of "macro-rules" which make problem solving more efficient. An intelligent computer assisted learning (ICAI) system is being developed which automatically acquires the useful knowledge from the domain experts; as experts give the learning…

This paper introduces and analyzes problems and issues in the design and use of cognitive tools in open, user-centered learning environments. It introduces a classification scheme for tool functions, and showcases several tools in a current educational hypermedia research and development effort. Information-seeking, information-presentation,…

Proposes principles for the design of effective document retrieval (DR) systems incorporating users' cognitive behaviors. Addresses three issues: (1) effective representations for documents to enable users' relevance judgments and decision making; (2) efficient presentations of documents to facilitate users' information processing and decision…

This paper makes basic assumptions regarding the development of an intranet architecture that will actively promote the cognitive apprenticeship of a new community of learners. The authors consider the intranet as a dynamic and virtual environment in which individuals may communicate, share resources, and reciprocally generate and organize…
