The invention discloses a network learning auxiliary method and system, and the method comprises the following steps: collecting an eye image under the irradiation of an infrared auxiliary light source when a user gazes at least one calibration point; positioning the iris inner boundary by searching a black connected domain internally containing light source image points and combining a radial gradient detection method, and positioning the iris outer boundary by the radial gradient detection method; extracting iris feature information in the range of the iris inner boundary and the iris outerboundary; determining the pupil center point position according to the iris inner boundary; searching an angular point near the pupil center point, and extracting the position of an inner eye angularpoint as an eye movement initialization characteristic parameter; and establishing gaze point calculation model. Further optimized embodiments also include a registration step, an authentication step,a gaze tracking step, and the like. The invention further comprises a network learning auxiliary system for implementing the method. The invention provides a high-cost-performance solution for effectively making statistics for online autonomous learning conditions of students.
Description
technical field [0001] The present application relates to the field of computer technology, in particular to an auxiliary method for network learning and an auxiliary system for network learning. Background technique [0002] The network self-learning system is a learning platform that uses modern Internet technology for course learning, which can realize fast, convenient, efficient and long-distance self-learning. But it is precisely because of its openness and autonomy that there are certain disadvantages when using it, which is not conducive to teachers' statistics of student attendance and mastering students' learning conditions, so that the effect of independent learning cannot be guaranteed. Therefore, it is very necessary to assist the network autonomous learning system to effectively count the students' online autonomous learning. Contents of the invention [0003] This application proposes an online learning assistance method and system, aiming at assisting the o...
