Eye-control man-machine interaction system and method

Abstract

The invention relates to an eye-control man-machine interaction system. The eye-control man-machine interaction system comprises an image collection device and a host, wherein the image collection device is used for collecting human face image information; and the host comprises an eye feature extraction module, a pupil center tracking module, a coordinate transformation module and a mouse simulation module; the eye feature extraction module is used for extracting eye feature information; the pupil center tracking module is used for tracking a pupil center and determining a pupil center coordinate; the coordinate transformation module is used for mapping the pupil center coordinate into a coordinate in a screen window; and the mouse simulation module is used for converting the coordinate in the screen window into a mouse instruction. The eye-control man-machine interaction system is easy to install, simple in operation and low in cost and can be used for helping disabled people to acquire more learning opportunities. The invention further relates to an eye-control man-machine interaction method.

Description

technical field [0001] The present invention relates to the technical field of artificial intelligence, in particular to an eye-controlled human-computer interaction system and method. Background technique [0002] With the development of computer technology, there are more and more operation commands and more and more functions. With the development of pattern recognition, such as speech recognition, Chinese character recognition and other input devices, it is possible for operators and computers to interact at a level similar to natural language or restricted natural language. [0003] Visual tracking technology uses changes in vision to replace the movement of human hands on the touch screen, so that people can still locate any area on the screen when they are far away from the screen. Using the touch screen through eye movement reduces many steps and accelerates the human-centered intelligent man-machine The development and realization of interaction, however, although ...

Problems solved by technology

[0003] Visual tracking technology uses changes in vision to replace the movement of human hands on the touch screen, so that people can still locate any area on the screen when they are far away from the screen. Using the touch screen through eye movement reduces many steps and accelerates the human-centered intelligent man-machine The development and realization of interaction, however, although the traditional gaze tracking technology has high tracking accuracy, it is expensive and complicated to use, especially the plug-in method, which not only restricts people's activities, but also brings great inconvenience to users. Uncomfortable feeling, difficult to be accepted by most people, only suitable for some special occasions
