Man-machine interaction method and e-mail sending method for server

The invention provides a man-machine interaction method and an e-mail sending method for a server. The man-machine interaction method comprises following steps: collecting face image sequences and hand image sequences of users; recognizing face motions of users according to face image sequences; recognizing gestures of users according to hand image sequences; collecting current fingerprint images in a fingerprint region in order to recognize fingerprint information used by the users currently; and determining corresponding computer instructions based on recognized face motions, gestures and fingerprint information used of the users and performing corresponding operation according to computer instructions. The above technical scheme of the man-machine interaction method and the e-mail sending method for the server can help improve secrecy and safety of a man-machine interaction process. 本发明提供了人机交互方法和用于服务器的电子邮件发送方法，人机交互方法包括：采集用户的脸部图像序列和手部图像序列；根据脸部图像序列，识别用户的脸部动作；根据手部图像序列，识别用户的手势；采集指纹区中当前的指纹图像，以识别用户当前所使用的指纹信息；基于已
