Automatic Emotion Recognition Based on Body Motion for Games
This on-going research project has been conducted in collaboration with the University of Cyprus since 2011. The research aims to develop an automatic system that can recognise emotions of game players based on their body motion information and with the use of motion analysis techniques.
