Johnson, Christopher W. – Human-Computer Interaction, 1996
The development of safety-critical systems (aircraft cockpits and reactor control rooms) is qualitatively different from that of other interactive systems. These differences impose burdens on design teams that must ensure the development of human-machine interfaces. Analyzes strengths and weaknesses of formal methods for the design of user…

Bodner, Richard C.; Chignell, Mark H.; Charoenkitkarn, Nipon; Golovchinsky, Gene; Kopak, Richard W. – Information Processing & Management, 2001
Compares empirical results from three experiments using Text Retrieval Conference (TREC) data and search topics that involved three different user interfaces. Results show that marking Boolean queries on text, which encourages browsing, and hypertext interfaces to text retrieval systems can benefit recall and can also benefit novice users.…

Marchionini, Gary; Geisler, Gary; Brunk, Ben – Proceedings of the ASIS Annual Meeting, 2000
Presents a framework for interface design that provides people with flexible control over different views for an information space, particularly on the World Wide Web. The agileviews framework defines overviews, previews, reviews, peripheral views, and shared views that help people make decisions about where they should focus attention during…

Breeding, Marshall – Computers in Libraries, 2005
This brief article gives a description of the Open Croquet Project and its applications. The project's Web site describes Croquet as a "combination of computer software and network architecture that supports deep collaboration and resource sharing among large numbers of users within the context of a large-scale distributed information system." One…

Luckin, Rosemary – Computers & Education, 2003
This paper discusses the development of a documentation technique for collaborative interactions. We describe the original version of the technique as used for a single learner collaborating with a software based learning partner; the second generation of the technique, which required adaptation for application to the analysis of group use of…

Wood, Simon; Romero, Pablo – Educational Technology & Society, 2010
Learner centred design methods highlight the importance of involving the stakeholders of the learning process (learners, teachers, educational researchers) at all stages of the design of educational applications and of refining the design through an iterative prototyping process. These methods have been used successfully when designing systems…

Nam, Chang S.; Smith-Jackson, Tonya L. – Journal of Information Technology Education, 2007
Web-based courses and programs have increasingly been developed by many academic institutions, organizations, and companies worldwide due to their benefits for both learners and educators. However, many of the developmental approaches lack two important considerations needed for implementing Web-based learning applications: (1) integration of the…

Lanzilotti, Rosa; Ardito, Carmelo; Costabile, Maria F.; De Angeli, Antonella – Educational Technology & Society, 2006
Quality of e-learning systems is one of the important topics that the researchers are investigating in the last years. This paper refines the concept of quality of e-learning systems and proposes a new framework, called TICS (Technology, Interaction, Content, Services), which focuses on the most important aspects to be considered when designing or…

Wang, James Z.; Du, Yanping – 2001
Statistical clustering is critical in designing scalable image retrieval systems. This paper presents a scalable algorithm for indexing and retrieving images based on region segmentation. The method uses statistical clustering on region features and IRM (Integrated Region Matching), a measure developed to evaluate overall similarity between images…
