Background: Palmtop computers provide a promising mobile platform to address barriers to computer-based supports for people with intellectual disabilities. This study evaluated a specially designed interface to make navigation and features of palmtop computers more accessible to users with intellectual disabilities. Method: The specialised…

The Web puts a huge number of learning resources within reach of anyone with Internet access. However, many valuable resources are difficult to find due to the lack of interoperability among learning repositories. In order to achieve interoperability, implementers require a common query framework. This paper discusses a set of methods referred to…

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…

Describes interfacing a hand-held oxygen probe with a microcomputer and suggests experiments for undergraduate chemistry courses that could facilitate student understanding of aquatic environmental processes which involve dissolved oxygen. Data can be analyzed through the program or exported into other software. Presents results of an experiment…

Develops a probabilistic model of the usage of an awareness-maintaining mechanism in a collaborative hypertext database system. Studies longitudinal time series data of user-database interaction. Finds that the recurring patterns in the occurrences of the awareness-seeking event were related to several contextual aspects of the Computer Supported…

Provides information on designing an effective and efficient computer user interface. Topics include determining an audience's mental model of the subject; creating effective navigation systems; components of the interface; what to consider when designing the interface; and the multimedia interface design process. (Author/LRW)

Describes the development of "Online" magazine, considers the impact it has had on its target audience of online searchers, and discusses changes in the online information field during the last 20 years. Topics include growth of the Internet; price competition; quality of information; and user interfaces. (LRW)

Demonstrates that college students' responses to a talking-face computer interface differ from their responses to a text-display interface. In reaction to a humanlike interface, subjects attributed some personality traits to it, were more aroused by it, and tended to present themselves more positively. Gender differences in interface reactions…

Discusses how the use of multiple windows affects online information design by examining key concepts and presenting a set of design principles based on research and the authors' experience designing online information. (TB)

Describes the building and testing of a robust pressure sensor suitable for use in schools that produces an output that can be fed into a standard computer interfacing set. (Author/NB)

TheBrain was created to take advantage of the most powerful information processor in existence - the human mind. Explains products of TheBrain Technologies Corporation,, which has developed computer interfaces to help individual users and corporations organize information in ways that make sense to them in the proper context. Describes a…

Describes the application of an integrated-circuit (IC) chip which provides an easy-to-use, inexpensive, rugged, computer-interfaceable temperature sensor for calorimetry and differential temperature measurement. Discusses its design and advantages. (JRH)

Describes a prototype system for software documentation management called SLEUTH (Software Literacy Enhancing Usefulness to Humans) being developed at the University of Virginia. Highlights include information retrieval techniques, hypertext links that are installed automatically, a WAIS (Wide Area Information Server) search engine, user…

Focuses on the user and human-computer interaction aspects of the research based on the Okapi text retrieval system. Three experiments implementing different approaches to query expansion are described, including the use of graphical user interfaces with different windowing techniques. (Author/LRW)

Describes the implementation of an intelligent tutoring system that employs a game environment and object-oriented user interface for teaching and learning, based on a computer game developed for industrial training. Discusses adventure games, game environments in education, simulation support, and user interface design. (Author/LRW)
