Geant4 is a software toolkit for the simulation of the passage of particles through matter. It is used by a large number of experiments and projects in a variety of application domains, including high energy physics, astrophysics and space science, medical physics and radiation protection. Its functionality and modeling capabilities continue to be extended,… (More)
This study examined how searchers interacted with a web-based, faceted library catalog when conducting exploratory searches. It applied eye tracking, stimulated recall interviews, and direct observation to investigate important aspects of gaze behavior in a faceted search interface: what components of the interface searchers looked at, for how long, and in… (More)
We describe a collaborative search system called Results Space to support small groups of users in conducting asynchronous collaborative searches. We discuss the design of the system and present results from a laboratory evaluation. We also describe the development of an asynchronous collaborative task scenario (based on a task from the TREC Robust test… (More)
In this paper we present the results of a study that investigates the relationships between search tasks, information architecture, and interaction style. Three kinds of search tasks (simple lookup, complex lookup and exploratory) were performed using three different user interfaces (standard web site, hierarchical text-based faceted interface, and dynamic… (More)
In this paper we describe a process for creating and evaluating exploratory tasks for a faceted search interface. We used the tasks in an eye tracking study of a faceted library catalog search interface. We report on user perceptions of the tasks. The method is intended to be extensible to generate exploratory tasks for other types of interfaces and domains.
This poster describes a procedure for designing exploratory tasks for use in laboratory evaluations of information seeking interfaces. This procedure is grounded in the literature on information seeking and information retrieval and has been refined by an evaluation of four tasks designed for a study of a faceted library catalog. The procedure is intended… (More)
Aggregated search is the task of blending results from different search services, or <i>verticals</i>, into a set of web search results. Aggregated search coherence is the extent to which results from different sources focus on similar senses of an ambiguous or underspecified query. Prior work investigated the "spill-over" effect between a set of blended… (More)
We present a Mozilla Firefox extension called the HCI Browser that we are developing to support studies of how users find and refind information on the Web. The HCI Browser presents tasks to the user, collects browser event data as they search for information, records answers found, and administers preand post-task questionnaires.
