论文摘要
近年来，各种类型网站的经验质量（QOE）引起了极大的关注。为了设计和评估网站，必须使用一个可以估算用户经验丰富的质量来鲁棒的指标。 SpeedIndex（SI）已被广泛采用，以估计感知到的网页加载进度。它测量了在浏览器窗口中可见的网页渲染像素的速度。这称为折叠（ATF）。动画内容对ATF感知的影响较少。在本文中，我们提出了一种实验设计和方法，用于测量具有和没有动画元素的各种页面内容类别的网站的ATF感知。我们发现，具有动画元素的页面导致人们在不同的网络条件下对ATF的看法更多。动画内容还会影响网站SI的页面加载估计精度。我们讨论ATF感知的差异将如何影响Web应用程序的QOE管理。我们解释了重新审视ATF视觉评估以包括动画内容并提高诸如SI等指标的鲁棒性的必要性。
Quality of Experience (QoE) for various types of websites has gained significant attention in recent years. In order to design and evaluate websites, a metric that can estimate a user's experienced quality robustly for diverse content is necessary. SpeedIndex (SI) has been widely adopted to estimate perceived web page loading progress. It measures the speed of rendering pixels for the webpage that is visible in the browser window. This is termed Above-The-Fold (ATF). The influence of animated content on the perception of ATF has been less comprehensively explored. In this paper, we present an experimental design and methodology to measure ATF perception for websites with and without animated elements for various page content categories. We found that pages with animated elements caused people to have more varied perceptions of ATF under different network conditions. Animated content also impacts the page load estimation accuracy of SI for websites. We discuss how the difference in the perception of ATF will impact the QoE management of web applications. We explain the necessity of revisiting the visual assessment of ATF to include the animated contents and improve the robustness of metrics like SI.
