Abstract
This study examines the design and evaluation of a key‐frame arrangement framework for video storyboard surrogates. First, we constructed an arrangement model of keyframes for a storyboard based on the Preserved Context Indexing System (PRECIS) and a narrative theory. Second, we evaluated the model using six sample videos and 26 participants, and then analyzed the results using a t‐test and repeated‐measure MANOVA. The results revealed that structurally arranged storyboards (STR) following the arrangement framework are not effective for either summarizing or indexing videos than sequentially arranged storyboards (SEQ) and that the repetition of viewing storyboards is effective for summarizing (not indexing) videos. The order of viewing two storyboards, regarding which of STR or SEQ comes first, is also crucial for improving subjects' summarizing ability. When subjects are viewing STR after SEQ, they summarize videos more effectively than viewing SEQ after STR.
