Human-machine interaction method and device based on sight tracing and gesture discriminating

The invention discloses a human-computer interaction method and a device based on vision follow-up and gesture identification. The method comprises the following steps of: facial area detection, hand area detection, eye location, fingertip location, screen location and gesture identification. A straight line is determined between an eye and a fingertip; the position where the straight line intersects with the screen is transformed into the logic coordinate of the mouse on the screen, and simultaneously the clicking operation of the mouse is simulated by judging the pressing action of the finger. The device comprises an image collection module, an image processing module and a wireless transmission module. First, the image of a user is collected at real time by a camera and then analyzed and processed by using an image processing algorithm to transform positions the user points to the screen and gesture changes into logic coordinates and control orders of the computer on the screen; and then the processing results are transmitted to the computer through the wireless transmission module. The invention provides a natural, intuitive and simple human-computer interaction method, which can realize remote operation of computers.

Video-based interaction method and device

The embodiment of the invention discloses a video-based interaction method and a video-based interaction device, and belongs to the field of a multi-media technology. The method comprises the steps of obtaining a target video and at least one interaction content corresponding to the target video, wherein the target video is configured with at least one interaction time point, and each interaction time point is configured with an interaction content relative to the corresponding video content; playing the target video; and displaying a target interaction content of each target interaction time point when the target video is used for playing the target interaction time point. The problems that the video interaction can be realized by relevant technologies by virtue of applying a third party, so as to cause that the video interaction lacks of independence and an interaction flow is more complicate can be solved; furthermore, the interaction content can be concomitantly displayed in the process of playing the video, the video interaction service can be provided for a user without the need of applying the third party, and the interaction flow can be simplified; in addition, the degree of fusion between the interaction content and the video content is higher, the method is beneficial for absorbing users to join the interaction, and the user experience is better.

Game role control method based on human face expression

The invention discloses a method for controlling game characters based on a human face analyzing technology. The method comprises the following steps: preprocessing an image obtained from an image input device simply and effectively; detecting the human face and positioning key points by a statistical learning method; and analyzing the positioning result to obtain human face gesture and expression information, and mapping the information to corresponding game control commands to achieve the real-time control function of the faces of the game characters. Using human face information of a player to control the game characters extends the interaction modes of the prior games by only shooting a picture of the human face of the player by a camera, analyzing the state and the expression information of the picture in a space, and converting the analyzed result into the control commands of the game characters. A video detection method of the invention is real-time, robust and easy to realize and operate. The method can enable game players to perform interactive operations in a more natural and more intellectual new mode, such as adopting self head gestures, face expressions and the like to endow games with more interactions and immersion.
