Sliders Versus Storyboards - Investigating Interaction Design for Mobile Video Browsing

We present a comparative study of two different interfaces for mobile video browsing on tablet devices following two basic concepts - storyboard designs representing a video’s content in a grid-like arrangement of static images extracted from the file, and slider interfaces enabling users to interactively skim a video’s content at random speed and direction along the timeline. Our results confirm the usefulness and usability of both designs but do not suggest a clear benefit of either of them in the direct comparison, recommending – among other identified design issues – an interface integrating both concepts.
