本文评估认知上合理的地理可视化技术映射运动数据。随着捕获个人运动轨迹的时空数据的可用性和质量的广泛增加,需要有意义的表示来使用地理显示器正确地可视化和传达轨迹数据和复杂的运动模式。已经提出了许多可视化和可视化分析方法来映射移动轨迹(例如,时空路径、动画、轨迹线等)。然而,人们对这些复杂的可视化在捕获运动数据的重要方面的有效性知之甚少。鉴于运动数据涉及空间、时间和上下文维度的复杂性,评估各种可视化形式在帮助人们理解运动数据方面的沟通效率和功效是至关重要的。本研究评估了静态和动态运动显示的有效性,以及视觉变量在沟通运动参数沿着轨迹,如速度和方向。要做到这一点,基于网络的调查进行评估的理解运动可视化的非专业观众。这项研究和未来的研究有助于对运动可视化的认知的基本见解,并启发了地理可视化经验评估的新方法。
This paper evaluates cognitively plausible geovisualization techniques for mapping movement data. With the widespread increase in the availability and quality of space-time data capturing movement trajectories of individuals, meaningful representations are needed to properly visualize and communicate trajectory data and complex movement patterns using geographic displays. Many visualization and visual analytics approaches have been proposed to map movement trajectories (e.g. space-time paths, animations, trajectory lines, etc.). However, little is known about how effective these complex visualizations are in capturing important aspects of movement data. Given the complexity of movement data which involves space, time, and context dimensions, it is essential to evaluate the communicative efficiency and efficacy of various visualization forms in helping people understand movement data. This study assesses the effectiveness of static and dynamic movement displays as well as visual variables in communicating movement parameters along trajectories, such as speed and direction. To do so, a web-based survey is conducted to evaluate the understanding of movement visualizations by a nonspecialist audience. This and future studies contribute fundamental insights into the cognition of movement visualizations and inspire new methods for the empirical evaluation of geovisualizations.
