The big reveal for Star Citizen at this year's Gamescom is the integration of Faceware's "3D facial motion capture", which will allow players to emote via their in-game avatar's face using, well, their face. The developer is labelling it as "Face Over Internet Protocol" or FoIP and will require sensor hardware from Faceware itself for the best results, however, it can work with a webcam though the "quality of facial detection may vary".
