Non-contact free space eye-gaze tracking method suitable for man-machine interaction

Abstract

The invention provides a non-contact free space eye-gaze tracking method suitable for man-machine interaction. The method comprises the steps of positioning and tracking a face and eyes in real time, extracting eye movement biological characteristic information, building an eye movement model based on the eye movement biological characteristic information, building a mapping relational model of the eye movement model and an eye-gazed object and the like. The non-contact free space eye-gaze tracking method suitable for the man-machine interaction relates to multiple crossed fields of image processing, computer vision, pattern recognition and the like and has wide application prospect in the fields of new-generation man-machine interaction, disabled people assisting, aerospace relating field, sports, automobile and airplane driving, virtual reality, games and the like. In addition, the method has great practical significance for improvement of the life and self-care level of disabled people, building of a harmonious society and improvement of independent innovative capability in the national high-and-new technical fields of the man-machine interaction, unmanned driving and the like.

Description

technical field [0001] The invention relates to the field of sight tracking applied to human-computer interaction and the technical field, in particular to a non-contact free-space line-of-sight tracking method suitable for human-computer interaction developed on the basis of computer image processing and pattern recognition. Background technique [0002] The traditional way of human-computer interaction is "computer-centric", that is, users are required to obey the rules of the computer before using it, so sometimes corresponding professional training is required. With the development and popularization of technology, the information society requires more "human-centered human-computer interaction" so that computers can serve everyone in society. The center of human-computer interaction should be transformed into human-centered, to achieve When the computer interacts, it is as if the human being interacts with himself. Among them, human life and activities are in three-dim...

Problems solved by technology

[0006] But at present, the volume and weight of the system equipment used to realize eye-tracking are relatively large, and at the same time, it also limits the degree of freedom of people, which interferes a lot with people, and is very inconvenient to use, and the price of commercial products is generally relatively expensive. , so it becomes more difficult to popularize eye-tracking devices
