The Landscape of Time-Based Visual Presentation Primitives for Richer Video Experience

Abstract

Abstract.As technology advances, we have increasingly more opportunities to use video for our knowledge work, such as monitoring events, reflecting on physical performances, learning subject matter, or analyzing scientific experimental phenomena. Existing video-related software tools are either for as-is viewing or editing and do not support such knowledge-intensive processes. We argue for a variety of interactive presentation tools for richer video experiences in active watching. Based on the Time-based Visual Presentation (TbVP) framework, which separates presentation from content and views interaction methods as transformations between temporal and visual media data properties and user experience properties, this paper presents twenty-seven TbVP primitives and provides the landscape of rich interaction methods for videos. The primitives are illustrated with five scenarios that use videos for knowledge work.

Sharing Video Browsing Style by Associating Browsing Behavior with Low-Level Features of Videos

“…The history of video browsing has been changing. We used to watch videos or TV programs passively (1), and then select videos on demand (2). Now we can interact with videos according to our own browsing style (3), however, we could not share these browsing styles.…”

“…1. (3)) [1]. However, such kind of tacit knowledge, which is acquired through user's experiences [2], has not been well managed.…”
