Abstract

The invention discloses a multi-mode information fusion-based classroom learning state monitoring method and system. The method specifically comprises the following steps of: acquiring an indoor sceneimage and positioning faces in the scene image; estimating face orientation postures in a face region so as to estimate attentions of students according to the face orientation postures; estimating facial expressions in the face region; acquiring skin conduction signals of the students so as to estimating physiological activation degrees of the students according to the skin conduction signals; recording interactive answer frequencies and correctness of the students on the classroom so as to estimate participation degrees of the students; and fusing four-dimensional information such as attention, learning moods, the physiological activation degrees and the classroom participation degrees of the students so as to analyze classroom learning states of the students. The invention furthermoreprovides a system for realizing the method. By applying the method and system, the learning states of students on classrooms can be objectively and correctly monitored and analyzed in real time, so that the teaching process analysis is perfected and the teaching effect differentiation degree is enhanced.

Description

technical field [0001] The invention belongs to the technical field of education informatization, and in particular relates to a classroom learning state monitoring method and system based on multimodal information fusion. Background technique [0002] With the rapid development of information technology, the application of educational informatization has also been continuously enriched and deepened. The school's information-based teaching environment has been preliminarily established. Information technology represented by multimedia and the Internet has been widely used, and new elements have been introduced into the presentation of teaching content and teaching activities. However, classroom teaching is mostly limited to the traditional teaching mode of "transfer-acceptance". The evaluation of teaching effect is mostly concentrated on the students' final exam scores, and the observation and analysis of teaching behavior mostly stays in the traditional questionnaire survey...
