摘要

讲师的指指手势很重要，因为它们似乎表明了教学意义。在这个扩展的摘要中，我们描述了一种简单的经验方法，用于检测使用深度传感器(Kinect)捕获的录制讲座中的指向手势。我们首先分析组成手势;其次，我们给它们分配权重;最后，我们在聚合权重上设置一个阈值，以确定是否执行了指向手势。

Empirical Method for Detecting Pointing Gestures in Recorded Lectures

Pointing gestures performed by lecturers are important because they seem to indicate pedagogical significance. In this extended abstract, we describe a simple empirical method for detecting pointing gestures in recorded lectures captured using a depth sensor (Kinect). We first analyse component gestures; second, we assign them weights; finally, we set a threshold on the aggregated weight in order to decide if a pointing gesture has been performed.
