The effect of text in storyboards for video navigation

A storyboard is a presentation scheme for abstracting information in a digital video clip based on imagery. This paper describes a series of storyboard interfaces with added transcript text features. These interfaces are used in a controlled experiment focusing on the utility of transcript text in storyboards for news video navigation. We wished to explore whether such text resulted in improvements in video navigation, and, if so, whether the amount of text and its synchronization with video imagery affected the navigation task. The text-augmented storyboards performed significantly better than storyboards with no text. Full transcript text produced benefits when presented as a block, whereas reduced contextual text descriptions produced benefits when aligned with storyboard image rows
