| 中文摘要: |
| 目的 从用户角度出发，研究移动设备网页浏览过程中网页时延与用户体验质量之间的关系。方法 通过记录多类网页浏览过程中不同时延下用户皮电、心电两类生理指标的变化，利用方差分析以及 t 检验计算其特征值发生显著性差异时对应的时延长度并对该时延长度进行标记，结合 MOS 评分量表， 对用户的主观感受作出评价。结果 实验得到了较为可靠的结论，研究发现不同移动网页时延下用户的体验质量是不同的。用户在打开网页时的主观体验与网页的时延长度整体存在非线性负相关关系。结论 当移动网页缓冲时延小于 1 s 时，用户体验良好；当时延超过 1 s 时，用户体验质量在一定时延范围内随时延增加而下降且该变化呈现较大的个人差异性；当时延超过 4 s 时，用户负面体验较为严重。 |

| From the perspective of users, the relationship between web page delay and user experience quality during mobile web browsing is studied. By recording the changes of two kinds of physiological indexes of the user's skin electricity and ECG during the multi-type web browsing process, the time delay length corresponding to the significant difference of its eigenvalues and the length of the time delay are marked by variance analysis and t test, and the subjective feelings of the users are evaluated by the MOS rating scale. The experimental results show that the quality of user experience is different under different mobile web pages. There is a nonlinear negative correlation between the subjective experience of users when opening web pages and the delay length of web pages. When the time delay of the mobile web page is less than 1 s, the user experience is good. When the time delay is more than 1 s, the user experience quality decreases at any time in a certain time delay, and the change presents a larger individual difference. At that time, the negative experience of the user is more serious than that of 4 s. |
