報告簡介：
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.
對手持設備的網絡搜索已經變得非常普遍和流行。盡管許多研究已經揭示了用戶如何在桌面機器上與搜索引擎結果頁面(serp)進行交互，但是在移動web搜索中與用戶交互相關的研究相對較少。搜索結果通常以類似的方式顯示，無論是在手機上還是在臺式機上。因此，當在小屏幕上搜索時，用戶和serp之間的關系仍然很困難，這意味著當前在移動設備上的SERPs可能不是最優的。在這次演講中，我們將考慮四個關鍵問題:桌面顯示器的屏幕尺寸和移動設備;不同大小的小屏幕上的搜索行為;移動web搜索中的水平視圖控制;以及片段長度對移動設備的影響。這項研究的目的是為了更好地理解用戶的移動網絡搜索行為。這些發現可以應用于廣泛的研究領域，如信息檢索、人機集成，甚至是社會科學，以便更好地呈現在移動設備上的SERP。
