Eye-2-I:用于即时隐式用户分析的眼动追踪

Eye-2-I: Eye-tracking for just-in-time implicit user profiling

摘要:

对于许多应用,例如定向广告和内容推荐,了解用户的特征和兴趣是先决条件。用户分析是实现这一目的的有用方法。然而,目前的方法,即自我报告、网络活动监测和社交媒体挖掘,要么是侵入性的,要么需要长时间的数据。近年来,越来越多的认知科学证据表明,各种用户的个人资料与眼动追踪数据显著相关。我们提出了一种新的即时隐式分析方法Eye-2-I,它可以在用户观看视频时从眼动追踪数据中学习用户的兴趣、人口统计和个性特征。虽然通过密切监视用户的眼睛行为看起来很显眼,但由于其独特的特性,我们的方法是不引人注目和保护隐私的,包括(1)快速-在第一个视频拍摄时即可获得配置文件,通常几秒钟,以及(2)独立-不依赖于历史数据或功能模块。[Bug作为一个概念验证,我们的方法进行了评估,在用户研究与51名受试者。在9分钟的眼动追踪数据中,它在用户简档的37个属性上实现了0.89的平均准确度。]

英文摘要:

For many applications, such as targeted advertising and content recommendation, knowing users' traits and interests is a prerequisite. User profiling is a helpful approach for this purpose. However, current methods, i.e. self-reporting, web-activity monitoring and social media mining are either intrusive or require data over long periods of time. Recently, there is growing evidence in cognitive science that a variety of users' profile is significantly correlated with eye-tracking data. We propose a novel just-in-time implicit profiling method, Eye-2-I, which learns the user's interests, demographic and personality traits from the eye-tracking data while the user is watching videos. Although seemingly conspicuous by closely monitoring the user's eye behaviors, our method is unobtrusive and privacy-preserving owing to its unique characteristics, including (1) fast speed - the profile is available by the first video shot, typically few seconds, and (2) self-contained - not relying on historical data or functional modules. [Bug found. As a proof-of-concept, our method is evaluated in a user study with 51 subjects. It achieved a mean accuracy of 0.89 on 37 attributes of user profile with 9 minutes of eye-tracking data.]
