Emotion Recognition Through Body Language Using RGB-D Sensor

This paper presents results on automatic non-acted human emotion recognition using full standing body movements and postures. The focus of this paper is to show that it is possible to classify emotions using a consumer depth sensor in an everyday scenario. The features for classification are body joint rotation angles and meta-features that are fed into a Support Vector Machines classifier. The work of Gaber-Barron and Si (2012) is used as inspiration and many of their proposed meta-features are reimplemented or modified. In this work we try to identify ”basic” human emotions, that are triggered by various visual stimuli. We present the emotion dataset that is recorded using Microsoft Kinect for Windows sensor and body joints rotation angles that are extracted using Microsoft Kinect Software Development Kit 1.6. The classified emotions are curiosity, confusion, joy, boredom and disgust. We show that human real emotions can be classified using body movements and postures with a classif ication accuracy of 55.62%.
