Abstract:Research questions were posed to examine users’ requests for information, beyond a keyframe, and certain influences thereof when interactively retrieving video. Laboratory-style search experiments employing 28 users from the field of science education were conducted. Users were asked to attempt six pre-designed search topics. All actions of the users and topic durations were recorded, and a post-search questionnaire was used to collect data about the topics and users’ experiences and impressions of the experimental system. Results showed that users regularly requested information about a clip, beyond a keyframe, while searching, not browsing, and that requests varied significantly across certain topic categories devised for this study. Users’ requests for information about a clip were negatively correlated with post-search satisfaction ratings, search times, and the number of actions performed. Findings also indicated that users' requests were not associated with a search topic's representation of the experimental domain. Such findings give researchers additional insight about user interface design for video digital libraries.
