    Abstract
    Reports progress and future plans for a project to study the interactions of users with information retrieval interfaces. Tests are run with professional data base searchers and with end users who are members of a profession but have little or no searching experience. Interfaces tested include a command language search system used to search DIALOG bibliographic data bases, a non-procedural system that produces DIALOG commands, and several full text systems, including one using hypertext. The intent is to determine which kinds of users perform best with each type of interface. The project is being conducted jointly bay the University of Toronto and the University of Maryland

    Abstract
    Discusses and illustrates the essential features of user-system interfaces designed to support end user searching. Presents examples of interfaces to support the following basic information seeking functions are presented: problem definition, source selection, problem articulation, examination of results, and information extraction. Argues that present interfaces focus on problem articulation and examination of results functions, and research and development are needed to support the problem definition and information extraction functions

    Abstract
    The purpose of this exploratory study is to develop research methods to compare the effectiveness of two video browsing interface designs, or surrogates-one static (storyboard) and one dynamic (slide show)-on two distinct information seeking tasks (gist determination and object recognition). Although video data is multimodal, potentially consisting of images, speech, sound, and text, the surrogates tested depend on image data only and use key frames or stills extracted from source video. A test system was developed to determine the effects of different key frame displays on user performance in specified information seeking tasks. The independent variables were interface display and task type. The dependent variables were task accuracy and subjective satisfaction. Covariates included spatial visual ability and time-to-completion. The study used a repeated block factorial 2x2 design; each of 20 participants interacted with all four interface-task combinations. No statistically significant results for task accuracy were found. Statistically significant differences were found, however, for user satisfaction with the display types: users assessed the static display to be "easier" to use than the dynamic display for both task types, even though there were no performance differences. This methodological approach provides a useful way to learn about the relationship between surrogate types and user tasks during video browsing
