这项工作提出了一种新的数据分析工具，称为时间隧道。Time-tunnel将任意数量的时间序列数值数据可视化为3D虚拟空间中的单个图表。通过在计算机屏幕上的直接操作，用户可以轻松地将两个以上的不同图表重叠在一起进行比较，以识别这些数据之间的相似性或差异。同时，在任何时间点显示这些数据之间的雷达图，以识别它们之间的相似性和相关性。通过这种方式，使用时间隧道，用户可以通过计算机屏幕上的交互式操作直观地分析多个时间序列数值数据。时间隧道不仅具有作为数据分析工具的方面，而且还具有作为基于图表的多媒体呈现工具的方面，因为时间隧道还处理多媒体数据，即，文本、图像、声音和电影，作为由位于图表的任何点处的标签表示的附加信息。作者还描述了有用的时间隧道作为一个多媒体演示工具。
This work proposes a new data analysis tool called Time-tunnel. Time-tunnel visualizes any numbers of time-series numerical data as individual charts in a 3D virtual space. Through direct manipulations on a computer screen, the user easily puts more than two different charts overlapped together to compare them in order to recognize the similarity or the difference among those data. Simultaneously a radar chart among those data at any time point is displayed to recognize the similarity and the correlation among them. In this way, using Time-tunnel, the user can visually analyse multiple time-series numerical data through interactive manipulations on a computer screen. Time-tunnel has not only aspects as a data analysis tool but also aspects as a chart-based multimedia presentation tool because Time-tunnel also treats multimedia data, i.e., texts, images, sounds and movies, as additional information represented by tags located at any point of charts. The authors also describe the usefulness of Time-tunnel as a multimedia presentation tool.
