Dynamic Graphics for the Data Analysis and Perception

在本研究中，我们的目的是研究人类视觉识别的特点表示的数据在统计数据分析与动态图形。为了进行研究，我们集中在两个主题;研究人员一直在研究的图形数据分析系统的扩展，以满足追求任务的需要和对系统视觉显示的感知的研究。为了评估数据显示的视觉感知，我们已经实现了创建适当的图片以评估数据的某些方面的能力，以及记录和重放系统用户的操作的设施。这些功能本身对于系统支持数据分析是必不可少的。对于处理动态图形的系统，记录的存储和基于记录的视图的重新显示等技术问题需要特别注意。在1996年的第14届大分统计会议上报告了该系统的实施问题<th>，在1998年的“大分大学工学部报告”中的两篇论文中给出了技术细节。在静态和动态图形中，研究了数据表示属性，如“形状”、“颜色”、“亮度”和“终止”对判断数据组大小的影响。目标变量是响应时间和响应的准确性。我们证实，动态运动的图形有一些特殊的属性，并确定了几个感知的影响。

In this research, we aimed to investigate characteristics of human visual recognition of representation of data in statistical data analysis with dynamic graphics. In order to pursue the study, we focused on two subject ; the extension of the graphical data analysis system, which the investigators have been working on, to meet the needs to pursue the task and the investigation of the perception to the visual display with the system.In order to assess the visual perception for the data display, we have implemented capability to create proper pictures to evaluate certain aspects of the data and facilities to record and replay the maneuver of the user of the system. These functions themselves are essential for the system to support the data analysis. For the system dealing with dynamic graphics, we had to pay special attention to the technical issues of storing the record and re-displaying views based on the record. Issues of the implementation were reported at the 14^<th> Oita Statistical Meeting in 1996 and technical details are given in two papers in "Reports of the Faculty of Engineering Oita University" in 1998.On the system, we conducted experiments of the perception for the data in scatter plots. The effects of data representation attributes, such as "shape", "color", "brightness" and "termination", on judging sezes of data groups are examined in stationary and dynamic graphics. Target variables were response time and accuracy of the response. We confirmed that graphs with dynamic motion had some peculiar characteristics on the attributes and identified several of the effects on the perception.
