Presents an exploratory study conducted to develop research methods to comapre 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. Develops a test system to determine the effects of different key frame displays on user performance in specified information seeking tasks. Finds no statistically signiicant results for task accuracy, but does find statistically significant differences for user satisfaction with display types. Concludes that this methodological approach provides a useful way to learn about the relationship between surrogate types and user tasks during video browsing. [ABSTRACT FROM AUTHOR] |
