Web page access is one of the most popular applications on the global Internet, and is a key element of the digital engine that drives the economy. While the technologies that support Web applications are well-developed and ubiquitous, mechanisms for high quality user experience have not been built into their development. (As one example, almost every user has experienced delays in accessing content while ads download.) Existing techniques for Web optimization focus on ensuring fast downloads, but research has shown that this has poor correlation with good user experience. Further, download speeds are limited by network conditions; network congestion or low access network bandwidth can make them painfully slow. This project aims to address this problem by developing techniques for Web page optimization that significantly improve user experience by downloading the content of value to the user first. This project's primary goal is to ensure that objects on a Web page are loaded in the order in which the user consumes them, thus significantly improving user experience. The key idea is to use user's eye gaze as a signal for user's consumption of Web objects (or alternately the user interest). The project will develop novel techniques to use gaze signal to prioritize Web page loads, using commercial eye-tracking technology, and leveraging the researchers' experience in eye-tracking in other applications. The fundamental contributions of this project are to (1) Develop a utility-driven optimization framework to dynamically reprioritize Web page loads based on the user eye gaze, object sizes, and network conditions; (2) Remove the human-in-the-loop by building high-level saliency models of eye gaze based on the characteristics of the Web page. The gaze tracking will only be used infrequently, to seed and update the model. (3) Design a large scale crowdsourced technique to track user gaze to drive the optimization and modeling; and (4) Evaluate the optimization and modeling specifically in terms of user experience by conducting large scale, crowdsourced, user evaluation.

网页访问是全球互联网上最流行的应用程序之一，也是驱动经济的数字引擎的关键要素。 尽管支持Web应用程序的技术已经成熟且无处不在，但高质量用户体验的机制尚未构建到其开发中。 （举个例子，几乎每个用户在下载广告时都会遇到访问内容延迟的情况。）现有的 Web 优化技术侧重于确保快速下载，但研究表明这与良好的用户体验相关性较差。 此外，下载速度受到网络条件的限制；网络拥塞或低访问网络带宽可能会导致速度极其缓慢。该项目旨在通过开发网页优化技术来解决这个问题，通过首先下载对用户有价值的内容来显着改善用户体验。 该项目的主要目标是确保网页上的对象按照用户使用它们的顺序加载，从而显着改善用户体验。关键思想是使用用户的视线作为用户消费 Web 对象（或者用户兴趣）的信号。该项目将开发新技术，利用注视信号来确定网页加载的优先级，使用商业眼动追踪技术，并利用研究人员在其他应用中眼动追踪的经验。该项目的基本贡献是（1）开发一个实用程序驱动的优化框架，根据用户的视线、对象大小和网络条件动态地重新确定网页加载的优先级； (2)根据网页的特征，建立高层的视线注视显着性模型，消除人机交互。凝视跟踪只会很少使用，用于播种和更新模型。 （3）设计大规模众包技术来跟踪用户视线以驱动优化和建模； (4) 通过进行大规模、众包的用户评估，专门针对用户体验来评估优化和建模。
