Human-computer interaction equipment and system based on facial features

Abstract

The invention provides a human-computer interaction equipment and system based on facial features, and the equipment comprises an image acquisition device, a processor, and a display screen. The image acquisition device is used for continuously acquiring user images; the processor is used for extracting a user face image in each user image in sequence, extracting facial feature information in each user face image, determining pose change information of the user, generating a corresponding control instruction according to the pose change information, executing a corresponding control operation on the preset video according to the control instruction, and sending the preset video after the control operation to a time counting display screen; and the display screen is also used for playing the preset video after the control operation. According to the human-computer interaction equipment and system based on the facial features provided by the embodiment of the invention, the current motion state of the face of the user is judged by detecting the biological features and the motion posture of the face of the human body, so that control signals such as pause or playing can be sent out, and video playing control through face motion is realized.
