It is critical that students learn how to retrieve useful information in hypermedia environments, a task that is often especially difficult when it comes to image retrieval, as little text feedback is given that allows them to reformulate keywords they need to use. This situation may make students feel disorientated while attempting image…

Information systems increasingly provide options for visually inspecting data during the process of information discovery and exploration. Little research has dealt so far with user interactions with these systems, and specifically with the effects of characteristics of the displayed data and the user on performance with such systems. The study…

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information…

This study investigates the relationships between the use of a zoom tool, the terms they supply to describe the image, and the type of image being viewed. Participants were assigned to two groups, one with access to the tool and one without, and were asked to supply terms to describe forty images, divided into four categories: landscape, portrait,…

End users think of file names as a way to identify file contents, whereas computer programs often assign special meaning to file extensions. This article discusses different kinds of files on the World Wide Web: text, document, sound, video, and multimedia; file compression; and encoding formats. Includes a chart of file formats and lists Web…

Explains the MEMOIR project (Managing Enterprise-scale Multimedia using an Open Framework for Information Re-use) that uses trails, open hypermedia link services and software agents to access and navigate information in Intranet environments to share technical information and find colleagues with similar interests. Presents results of evaluations…

This paper presents a high-level course in computing for non-majors offered at Queens College (New York). The course focuses on the acquisition and presentation of data and information. For data acquisition, the course will give the students high-level mastery of the Internet. For the presentation of information, the students will learn multimedia…

To help students learn to navigate the information superhighway, a 2-hour pilot program with 10 hours of guided access time was developed to test a method for teaching the basics of maneuvering the superhighway and extracting information once located. This pilot was designed as a two-part instructional session. The first instructional session…

Production of the meta-data supporting the Informedia Digital Video Library interface is automated using techniques derived from artificial intelligence research. Speech recognition and natural-language processing, information retrieval, and image analysis are applied to produce an interface that helps users locate information and navigate more…
