摘要

走神是一种普遍存在的现象，是指注意力不自觉地从任务相关的加工过程转移到与任务无关的思维过程。本研究报告了在电影观看过程中基于视频的毫瓦检测器的初步结果。我们在一项研究中收集了训练数据，参与者在观看32.5分钟的商业电影的过程中，自我报告了他们什么时候发现自己喝醉了。我们在自动提取的面部特征和身体运动上训练分类模型，能够以0.30的F1检测出MW。该模型成功地再现了从自我报告中获得的MW分布

Where's Your Mind At?: Video-Based Mind Wandering Detection During Film Viewing

Mind wandering (MW) is a ubiquitous phenomenon in which attention involuntarily shifts from task-related processing to task-unrelated thoughts. This study reports preliminary results of a video-based MW detector during film viewing. We collected training data in a study where participants self-reported when they caught themselves MW over the course of watching a 32.5 minute commercial film. We trained classification models on automatically extracted facial features and bodily movement and were able to detect MW with an F1 of .30. The model was successful in reproducing the MW distribution obtained from the self-reports
