报告简介：

Web search on hand-held devices has become enormously common and popular. Although a number of studies have revealed how users interact with search engine result pages (SERPs) on desktop machines, there are comparatively few studies related to user interaction in mobile web search. Search results are commonly shown in a similar way whether on a mobile phone or a desktop. Therefore, it is still difficult to know what happens between users and SERPs when searching on small screens, and this means that the current presentation of SERPs on mobile devices may not be optimal.

In this talk, four key issues will be considered: screen size for desktop monitors vs mobile devices; search behaviour on different sized small screens; horizontal viewport control in mobile web search; and the effect of snippet length on a mobile device.

The research has been conducted with a view to better understanding users mobile web search behaviour. The findings can be applied to a wide range of research areas such as information retrieval, human-computer integration, and even social science for better presentation of SERP on mobile devices.

对手持设备的网络搜索已经变得非常普遍和流行。尽管许多研究已经揭示了用户如何在桌面机器上与搜索引擎结果页面(serp)进行交互，但是在移动web搜索中与用户交互相关的研究相对较少。搜索结果通常以类似的方式显示，无论是在手机上还是在台式机上。因此，当在小屏幕上搜索时，用户和serp之间的关系仍然很困难，这意味着当前在移动设备上的SERPs可能不是最优的。在这次演讲中，我们将考虑四个关键问题:桌面显示器的屏幕尺寸和移动设备;不同大小的小屏幕上的搜索行为;移动web搜索中的水平视图控制;以及片段长度对移动设备的影响。这项研究的目的是为了更好地理解用户的移动网络搜索行为。这些发现可以应用于广泛的研究领域，如信息检索、人机集成，甚至是社会科学，以便更好地呈现在移动设备上的SERP。
