【摘要】 超视频打破了传统视频的单一线性的组织和浏览方式,有效地增强了用户的浏览效率和视频信息的表达能力。本文基于草图和草图界面在思维表达上的优势,针对当前对视频内容以及视频间或者视频内的关系展示上的不足,提出了一种支持超视频创建的草图界面来直观地表达用户的设计意图,改善了视频编辑过程中的交互体验,并给出了一种改进的基于Force-Directed的图布局算法,对超视频的动态创建和编辑过程进行呈现。更多还原

【Abstract】 Due to its nonlinear potential, hyper video presents the improvement for users’ browsing efficiency and visual information’s representation ability compared with that of traditional video. Based on the advantages of sketch and sketch based interface, this paper provides an intuitive sketch based interface for supporting hyper video creation to describe users’ intention and improve user experiences. Furthermore, a force-directed graph layout algorithm for representing video semantics is discussed. It is an intuitive method to represent the dynamitic process of creation and modification for hyper videos.更多还原
