Abstract—A recognition method for simple gestures is pro-posed and evaluated. Such gestures are of interest as they are the primitive elements of more complex gestures utilized in natural communication and human computer interaction. The input to the recognition method is obtained from a head tracker that is based on images acquired from a depth camera. Candidate gestures are detected within continuous head motion and recognized, acknowledging that head pose estimates might be inaccurate. The proposed method is evaluated within the context of human-computer dialog.The reported results show that the proposed approach yields competitive recognition results to state-of-the-art approaches. Index Terms—head gesture recognition; head gesture detection. I.
