视觉话语是一系列相连的视觉显示。连贯的视觉话语需要显示器之间的平滑过渡、显示器内部和显示器之间的一致设计以及将新信息成功集成到现有显示器中。我们提出了一种自动设计连贯视觉话语的方法。使用自上而下的分层分解偏序规划器来有效地规划视觉话语。视觉表示被建模为视觉对象，图形技术被用作规划运算符，设计策略被编码为约束。与基于搜索的方法相比，这种方法不仅提高了计算效率，而且有利于知识编码，并确保全局一致性。
A visual discourse is a series of connected visual displays. A coherent visual discourse requires smooth transitions between displays, consistent design within and across displays, and successful integration of new information into existing displays. We present an approach for automatically designing a coherent visual discourse. A top-down, hierarchical-decomposition partial-order planner is used to efficiently plan the visual discourse. Visual representations are modelled as visual objects, graphical techniques are employed as planning operators, and design policies are encoded as constraints. This approach not only improves the computational efficiency compared to search-based approaches, but also facilitates knowledge encoding, and ensures global coherency.
