摘要/Abstract

摘要：

个人地理标记数据是个人通过笔记本、平板电脑或者手机等设备发布的包含地理位置且与个人相关的文本、照片和视频等信息。本文针对个人地理标记数据的特点, 提出了一种适用于地理标签数据的可视化方法——个人地理标记数据拓扑图, 并设计和实现了核心算法。为了比较和评估该方法的效能, 对“文本列表”、“普通地图”和“标记拓扑图”3种用户界面进行可用性测试, 并对测试数据进行方差分析。测试结论表明, 3种不同用户界面在查找个人地理标记数据的效率方面存在显著性差异, 其中文本列表和标记拓扑图均优于普通地图, 文本列表和标记拓扑图在查找时间上的差异并不显著, 标记拓扑图在查找时间均值上略优于文本列表。

关键词: 可视化, 个人地理标记数据, 可用性测试, 方差分析

Abstract:

Geotagged personal datas, which are released by laptop, tablet PC or mobile device,contain personal data such as text, photos, video information and geographic position information. In this paper, we propose a new visualization method—the topological map of personal geotagged data (simply, the topological map) and provide the design and implementation of the core algorithm for the method. In order to evaluate the effectiveness of the method, we conduct a usability test for "a text list", "a thematic map" and "a topological map" and use analysis of variance(ANOVA) to deal with test data. The results show that the three kinds of user interfaces have statistically significant difference in terms of efficiency in finding personal geotagged data, and there are not significant difference between a text list and a topological map, while the latter is slightly faster than the former, however, both are significantly better than a thematic map.

Key words: visualization, personal geotagged data, usability test, AVOVA
