Abstract

Automatic emotion recognition was of great value in many applications, however, to fully display the application value of emotion recognition, more portable, non-intrusive, inexpensive technologies need to be developed. Except face expression and voices, human gaits could reflect the walker's emotional state too. By utilizing 59 participants' gaits data with emotion labels, we train machine learning models that are able to “sense” individual emotion. Experimental results show these models work very well, proved that gait features are effective in characterizing and recognizing emotions.
