Abstract

The invention discloses a real-time evaluation method and system for a network piano lesson, and relates to the technical field of network communication. The real-time evaluation method is characterized in that the attendance rate of students is firstly counted at the beginning of the lesson, then the piano playing intonation rate of the students is calculated according to audio signals acquired by a student terminal, the number of positive expressions in facial expressions of the students is counted according to image signals acquired by the student terminal, finally comprehensive evaluation for a teacher is calculated according to the attendance rate of the students, the playing intonation rate and the number of the positive expressions, a teacher terminal displays the evaluation and reminds the teacher to adjust the teaching method timely. Real learning conditions of the students are acquired in real time, and the calculation result is objective and accurate, so that the real-time evaluation method has very high application values.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a real-time evaluation method and system for network piano lessons. Background technique [0002] Piano is currently the main means of entertainment. With the development of society, the proportion of children taking piano courses is getting higher and higher. Existing piano courses are generally physical courses, and there are fewer online courses. [0003] Online courses are less binding on people, so students can evaluate at will without scruples, so the evaluation of teachers in online courses is not very reliable. Moreover, most of the evaluation methods currently used are after-class evaluation. After the course is over, students often forget what is not good in the learning, so the accuracy of evaluation is not high. Contents of the invention [0004] Embodiments of the present invention provide a real-time evaluation method and system for online piano les...
