摘要

我们对26名小学生进行了实验，测量了他们在观看儿童新闻电视节目时的目光运动，并分析了这些运动与学生对节目内容的理解之间的关系。实验电视节目结束后，以小测验的方式获取理解数据。我们通过计算估计的凝视方向概率分布的熵来评估它们凝视方向的方差，这些概率分布被表示为二维正态分布的混合物。结果表明，对于理解能力较强的场景，注视方向的差异往往较小。在说出与相应问题的答案相关的关键词后，这种趋势很明显

Objectively Evaluating TV Programs by Using a Viewer's Gaze Direction

We conducted experiments on 26 elementary school pupils to measure the movements of their gaze while they were watching a news TV program for children and analyzed the relationship between the measurements and the pupil's comprehension of the program's contents. The comprehension data were acquired with a quiz-style examination after the experimental TV program. We evaluated the variances of their gaze directions by calculating entropy of the estimated gaze direction probability distributions that were represented as a mixture of two-dimensional normal distributions. The results indicate the variances of the gaze direction for scenes that gave better comprehension tended to be lower. The tendency was noticeable after a keyword utterance related to the answer to the corresponding question
