| 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.基于草图和草图界面在思维表达上的优势，针对目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.提出了一种基于force-directed 的图布局算法.该算法对视频语义进行建模，将时间、空间、视频结构、约束关系等语义信息融入到节点质量、引力和斥力等对象中.系统实例表明，该方法能够很好地适应视频特有的语义类型，表示出超视频的动态创建和编辑过程.

| Abstract: | Due to its nonlinear potential, hyper video offers improvement in 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. This algorithm constructs a model for video semantics. It brings attributions such as temporal or spatial information, video structure and constraints between video clips into mass of nodes and attractive forces or repulsive force of edges in the force-directed graph. Result shows that it is an intuitive method to represent the dynamitic process of creation and modification for hyper videos. |
