This paper compares the usability of three different content distribution methods (scrolling, paging and internal links) in touchscreen mobile devices as means to display web documents. Usability is operationalized in terms of effectiveness, efficiency and user satisfaction. These dimensions are then measured in an experiment (N = 23) in which users are required to find words in regular-length web documents. Results suggest that scrolling is statistically better in terms of efficiency and user satisfaction. It is also found to be more effective but results were not significant. Our findings are also compared with existing literature to propose the following guideline: "try to use vertical scrolling in web pages for mobile devices instead of paging or internal links, except when the content is too large, then paging is recommended". With an ever increasing number of touchscreen web-enabled mobile devices, this new guideline can be relevant for content developers targeting the mobile web as well as institutions trying to improve the usability of their content for mobile platforms.
本文比较了三种不同内容分发方式（滚动、分页和内部链接）在触摸屏移动设备上作为显示网页文档手段的可用性。可用性从有效性、效率和用户满意度方面进行操作化定义。然后在一项实验（N = 23）中对这些维度进行测量，在该实验中，要求用户在常规长度的网页文档中查找单词。结果表明，在效率和用户满意度方面，滚动在统计学上表现更好。还发现滚动更有效，但结果不显著。我们的研究结果还与现有文献进行了比较，以提出以下指导原则：“对于移动设备的网页，尝试使用垂直滚动而不是分页或内部链接，除非内容太大，此时建议使用分页”。随着支持触摸屏的移动设备数量不断增加，这条新的指导原则对于面向移动网络的内容开发者以及试图提高其内容在移动平台上可用性的机构可能具有参考价值。
