Abstract

The invention discloses a method for measuring the focus of attention, which measures the head offset data of the test object in real time, estimates the position of the focus of attention of the test object according to the measurement data, and eliminates the attention of some test objects through abnormal discrimination and clustering Group attention measurement error caused by dispersion; Applying this attention focus measurement method provided by the present invention to monitor classroom situation in classroom environment can provide reliable and intuitive data for understanding students' class status, and for students' learning in current classroom teaching. Monitoring of the situation is of high value.

Description

technical field [0001] The invention belongs to the field of information processing, and more particularly, relates to a method for measuring attention focus. Background technique [0002] With the development of science and technology, information intelligence has been widely used in various fields in people's daily life. In the field of teaching, the focus of students' attention during lectures is an indicator that managers and teachers attach great importance to. [0003] At present, most of the existing measurement systems and methods for students' attention focus are measured by detecting the sight of students; there are two methods: short-range measurement and long-distance measurement; for short-range line-of-sight measurement, front-end measuring instruments are mostly used, such as Tobii Etc., when the human body posture is basically fixed, the sight line data of the students at close range can be measured more accurately, so as to calculate the position of the stu...
