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(duì)手持設(shè)備的網(wǎng)絡(luò)搜索已經(jīng)變得非常普遍和流行。盡管許多研究已經(jīng)揭示了用戶(hù)如何在桌面機(jī)器上與搜索引擎結(jié)果頁(yè)面(serp)進(jìn)行交互，但是在移動(dòng)web搜索中與用戶(hù)交互相關(guān)的研究相對(duì)較少。搜索結(jié)果通常以類(lèi)似的方式顯示，無(wú)論是在手機(jī)上還是在臺(tái)式機(jī)上。因此，當(dāng)在小屏幕上搜索時(shí)，用戶(hù)和serp之間的關(guān)系仍然很困難，這意味著當(dāng)前在移動(dòng)設(shè)備上的SERPs可能不是最優(yōu)的。在這次演講中，我們將考慮四個(gè)關(guān)鍵問(wèn)題:桌面顯示器的屏幕尺寸和移動(dòng)設(shè)備;不同大小的小屏幕上的搜索行為;移動(dòng)web搜索中的水平視圖控制;以及片段長(zhǎng)度對(duì)移動(dòng)設(shè)備的影響。這項(xiàng)研究的目的是為了更好地理解用戶(hù)的移動(dòng)網(wǎng)絡(luò)搜索行為。這些發(fā)現(xiàn)可以應(yīng)用于廣泛的研究領(lǐng)域，如信息檢索、人機(jī)集成，甚至是社會(huì)科學(xué)，以便更好地呈現(xiàn)在移動(dòng)設(shè)備上的SERP。
