Abstract
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.
