在可视化中使用的大多数显示设备是2D显示器。不可避免地，通常需要将一条视觉信息叠加在另一条视觉信息上，特别是在多场可视化和地理空间信息可视化等应用中。在本文中，我们提出了一个概念框架，研究机制，覆盖多条视觉信息，同时允许用户恢复闭塞的信息。我们采用电信和数据通信中的“多路复用”一词来涵盖所有这些重叠的机制。我们建立了10类视觉复用机制。我们从感知文献和现有的可视化作品中得出支持证据来支持这个概念框架。我们研究复用和信息理论的措施之间的关系。这种新的概念分类提供了急需的可视化理论的一个组成部分。
The majority of display devices used in visualization are 2D displays. Inevitably, it is often necessary to overlay one piece of visual information on top of another, especially in applications such as multi-field visualization and geospatial information visualization. In this paper, we present a conceptual framework for studying the mechanisms for overlaying multiple pieces of visual information while allowing users to recover occluded information. We adopt the term 'multiplexing' from tele-and data communication to encompass all such overlapping mechanisms. We establish 10 categories of visual multiplexing mechanisms. We draw support evidence from both perception literature and existing works in visualization to support this conceptual framework. We examine the relationships between multiplexing and information theoretic measures. This new conceptual categorization provides the much-needed theory of visualization with an integral component.
