How Does Animation Work? Eye-Movement Analysis of Dynamic Geovisualization Displays

动画是如何工作的？动态地理可视化显示的眼动分析.随着实时三维景观漫游和各种空间扩散过程的交互式制图通过互联网的传播变得无处不在，剩下的关键问题是这些高度交互式视觉形式的信息密度的潜在增加对于学习、知识构建本项目的主要目标是实证评估交互式和动态地理可视化显示对知识发现和知识构建的有效性。基于认知科学的研究框架，利用眼动视觉采集方法，设计了一系列受控动画实验。这些实证研究坚持认知科学中的实验设计标准，但也基于从制图学，计算机图形学和电影摄影学中借来的动态设计框架，以研究动态视觉变量，与静态显示相比，不同层次的交互性影响着人们从动态显示中构建知识的过程，本研究的结果将有助于加深对人们如何使用动态显示的理解探索动态地理现象，以及人们如何从动态可视化中进行推理，以在地理环境中构建知识。一个动态的设计框架将被开发的结果从眼动研究。这个框架将包括为学者和设计师设计的指南，他们都采用动态图形显示来教育，做研究，和/或交流动态空间现象的研究结果。

How does animation work?Eye-movement analyses of dynamic geovisualization displays.As real-time three-dimensional landscape fly-throughs and interactive mapanimations of various spatial diffusion processes become ubiquitous withdissemination through the Internet, the key question that remains is howeffective the potential increase of information density in these highlyinteractive visual forms really is for learning, knowledge construction,and knowledge dissemination and education.The main goal of this proposed project is to empirically evaluate theeffectiveness of interactive and dynamic geographic visualization displaysfor knowledge discovery and knowledge construction. Based on a researchframework from cognitive science, and utilizing the eye-movement datacollection approach, a series of controlled animation experiments areproposed. These empirical studies adhere to experimental design standardsin cognitive science, but are additionally grounded on a dynamic designframework borrowed from cartography, computer graphics and cinematography,to investigate how dynamic visual variables, and various levels ofinteractivity affect people's knowledge construction processes fromdynamic displays as compared to static displays.The outcome of this investigation will be a increased understanding of howpeople use dynamic displays to explore dynamic geographic phenomena, andhow people make inferences from dynamic visualizations for knowledgeconstruction in a geographical context. A dynamic design framework will bedeveloped informed by the outcomes from the eye-movement studies. Thisframework will include design guidelines for academics and practitionersalike, both of whom employ dynamic graphic displays to educate, to doresearch, and/or to communicate research results on dynamic spatialphenomena.
