A multimodal system for public speaking with real time feedback has been developed using the Microsoft Kinect. The system has been developed within the paradigm of positive computing which focuses on designing for user wellbeing. The system detects body pose, facial expressions and voice. Visual feedback is displayed to users on their speaking performance in real time. Users can view statistics on their utilisation of speaking modalities. The system also has a mentor avatar which appears alongside the user avatar to facilitate user training. Autocue mode allows a user to practice with set text from a chosen speech.
