Visual guidance-based mobile game system and mobile game response method

A visual guidance-based mobile game system, comprising a terminal and a gamepad connected with the terminal, wherein

• the terminal is provided thereon with an image acquisition device configured to acquire an eye movement image of a mobile game user;
• the terminal comprises a user interface module configured to receive the eye movement image and output a mobile game response;
• the mobile game system comprises an eye tracker;
• the mobile game system comprises a visual intelligent guidance module and a data processing module that are connected with the user interface module;
• the eye tracker converts the eye movement image into eye tracking information;
• the visual intelligent guidance module is configured to transmit the eye tracking information to the data processing module;
• the data processing module is configured to determine a responsive instruction corresponding to the eye tracking information according to the eye tracking information, so as to guide a control point on a screen of the terminal according to the responsive instruction and complete the mobile game response,
• the visual intelligent guidance module comprises an image processing unit configured to convert the eye movement image into a gray-scale image and an edge extraction unit configured to extract the eye tracking information from the gray-scale image,
• wherein the edge extraction unit comprises an eye contour feature extraction sub-unit, an iris contour feature extraction sub-unit and an iris center point movement deviation calculation sub-unit;
• the eye contour feature extraction sub-unit is configured to lock an eye part of the mobile game user;
• the iris contour feature extraction sub-unit is configured to perform iris center point positioning on the eye part;
• and
• the iris center point movement deviation calculation sub-unit is configured to determine a movement deviation (Xp, Yp) of an iris center point by (Xp, Yp)=(X1, Y1)−(X0, Y0), where (X0, Y0) is coordinates of the iris center point when it is at a center of the eye part, and (X1, Y1) is coordinates of the iris center point after movement.
