This paper presents a user-centred design and evaluation methodology for ensuring the usability of IR interfaces. The methodology is based on sequentially performing: a competitive analysis, user task analysis, heuristic evaluation, formative evaluation and a summative comparative evaluation. These techniques are described, and their application…

This paper discusses a generic query tool that enables an end user to query a metadata store through filters that impose search criteria on attributes. The Metadata Query Tool (MQT) is generic in the sense that it dynamically creates its user interface, based on configuration files that define the metadata scheme and the query functionalities.…

A museum can talk to its audience through a variety of channels, such as Web sites, help desks, human guides, brochures. A considerable effort is being made by museums to integrate these different means. The Web site can be designed to be reachable or even updateable from visitors inside the museum via touchscreen and wireless devices. But these…

This paper reports the findings from a field study of legal research in a first-tier law school and on the resulting redesign of XLibris, a next-generation e-book. The report first characterizes a work setting in which an e-book was expected to be a useful interface for reading and otherwise using a mix of physical and digital library materials,…

Studied how toddlers respond to interactive multimedia. Found that 2- to 3-year olds can engage in computer interactions, but that purposeful and meaningful interactions may not begin until children are about two-and-a-half years old. Prior knowledge plays a strong role in toddlers' computer experience. Human interaction is vital to help…

Describes the GEM (Gateway to Educational Materials) project being developed to provide enhanced access to lesson plans and other Internet-based educational materials through metadata. Highlights include controlled vocabularies; NIDR (networked information discovery and retrieval); the Dublin Core element set; syntax; prototype interfaces; and…

Describes the development of a new interface called GPO Gate for accessing the Government Printing Office (GPO) WAIS (wide area information server) databases, GPO Access. Highlights include development and use of GPO Gate at the University of California, San Diego, and implications for public service. (Author/LRW)

Examines trends in World Wide Web searching; reviews new search services; and describes changes in major Web search services. Highlights include commercial sites, subject access, target audience, custom interfaces, concept searching, and results lists. (LRW)

Discusses software design for enterprise systems and for video games, and describes difficulties with enterprise tools, including interface complexity, training costs, and user frustration. Examines the world of tools and games from the human perspective and suggests ways in which game design can be successfully transferred to the enterprise tool…

Describes a measurement system for recording the frequency response of acoustic systems. The computer interface detects the characteristic modes, their relative strengths, and resonant shapes over a broad range of frequencies. Includes experimental data for tubes and analyzes the data to determine the optimal functional form for the resonant…

Focuses on practices related to the use of a microcomputer-based laboratory (MBL) in a high school chemistry course in which students studied gases and kinetic theory. Reports that little or no higher order thinking was employed as students engaged in using the MBL and that some alternative conceptions were still evident. (Contains 42 references.)…

Discusses qualitatively enhanced access to data collections, requiring a more meaningful interface which endows the users with personal agents that are adaptable to the users' individual retrieval preferences. Users are given recommendations derived from best practice in information search processes to perform successful retrieval activities via…

Presents three motion experiments that use magnetic switches for marking position and time involving an inclined plane, an air track, and sprinting. (JRH)

Presents activities using thermocouples to investigate the temperatures at which candles burn and popcorn pops. (MKR)

Explores the principles and theories relevant to the design of effective hypermedia courseware. Proposes a hypermedia design: micro-(node) design, dealing with the creation of discrete information screens; and macro-(links), dealing with the connections between them. Presents a prototype courseware template and a courseware unit based on design…
