FaceShare: Mirroring with Pseudo-Smile Enriches Video Chat Communications


FaceShare is a videophone system, which can augment the remote-communication by generating a pseudo-smile. When FaceShare detects that the partner is smiling, it starts to deform the user's face into a smile. We implemented a prototype videophone system which can deform the user's face into a smile in response to their partners' smiling. A 3D camera is used to capture an image of the user's face and detect the feature points and the intensity of the user's smiling. The deformed user's image is generated and fed to a video stream, and the partner's smile intensity can be obtained in real time between browsers via WebRTC. We conducted an experiment in which pairs of participants had brief conversations via FaceShare. The result implied that FaceShare enhances the mimicker's feeling of closeness toward the mimickee, and improves the subjective smoothness of a conversation for both the mimicker and the mimickee.
