When i was watching videos on youtube, i noticed that their is something called face tracking or face recognition, basically you have to have a camera, and any expression you do in the real life infront of the camera will get into the game making it similar to what you did with your face, making the game more realistic.
i want to know will this be in identity in the near future or it's not a priority?
Here is a video to explain how it works and how does it look like.
