ABSTRACT

For designing qualitative interfaces for Public Participatory Geographic Information Systems (PPGIS), the user and use case should be clearly defined. However, PPGIS users may differ significantly, e.g. regarding their cultural background, IT-literacy, or interests. Studies examining varying user types and their impact on PPGIS usability are, however, lacking. In this paper, we analyse the user spectrum through conducting a usability study with 73 participants located in Colombia, Uganda and Austria. We combined a qualitative survey (conducted in all three countries) with an eye-tracking based survey (conducted only in Austria). Most of the usability issues arose due to inexperience in using interactive maps or applications other than social media. Based on the findings, we explored which user context information had an impact on which usability problem. With this, we designed an adaptation gradient that can be used for future research on developing adaptive PPGIS interfaces.

摘要

为了设计公共参与式地理信息系统 (PPGIS) 的定性界面，应明确定义用户和用例。然而，PPGIS 用户可能存在显着差异，例如关于他们的文化背景、IT 素养或兴趣。然而，缺乏对不同用户类型及其对 PPGIS 可用性影响的研究。在本文中，我们通过对位于哥伦比亚、乌干达和奥地利的 73 名参与者进行可用性研究来分析用户频谱。我们将定性调查（在所有三个国家进行）与基于眼动追踪的调查（仅在奥地利进行）相结合。大多数可用性问题是由于缺乏使用社交媒体以外的交互式地图或应用程序的经验引起的。根据调查结果，我们探讨了哪些用户上下文信息对哪些可用性问题有影响。有了这个，我们设计了一个自适应梯度，可用于未来开发自适应 PPGIS 接口的研究。
