Hi, currently there is only eye tracking based on Tobii Tracking and lipsync based on voice input. Gestures, facial expressions etc. are triggered using keyboard shortcuts but need to come with the model in form of animations.
Support for face tracking based on your actual face is not yet available.
Leap motions support is one of the features I am working on currently.
I suggest you try for example VSeeFace instead as it fits you better. It comes with webcam tracking and leap motion support.
