Systems and methods are provided for augmented-reality interactions based on face detection. For example,a video stream is captured；one or more first image frames are acquired from the video stream；face-detection is performed on the one or more first image frames to obtain facial image data of the one or more first image frames；camera-calibrated parameter matrix and an affine- transformation matrix corresponding to user hand gestures are acquired；and a virtual scene is generated based on at least information associated with calculation using the facial image data in combination with the parameter matrix and the affine-transformation matrix.
