Research On Guzheng Primary Fingering Practice System Based On Gesture Recognition

With the rapid development of the intelligent instrument teaching market,the relevant policies of "Internet plus teaching" have also been proposed.However,offline teaching remains the main teaching mode for guzheng learning,with low intelligence and high teaching and learning costs.Based on gesture recognition technology,this research provides adaptive feedback information for the beginners of zither with interest motivation in their independent practice after class to solve the problem of low practice efficiency caused by the lack of correct and sufficient feedback information.This article focuses on building an exercise system that supports providing feedback information.The specific work is as follows:The first step is to refine and decompose the knowledge points of Guzheng fingering,and clarify the corresponding specific knowledge points for feedback.Specifically,based on the precise teaching theory,the requirements for precise decomposition and matching of teaching content are proposed.The knowledge points of Guzheng fingering are decomposed from the operational dimension of Guzheng fingering movements,and a four stage practice mode of fingering indicators and precise practice is constructed.The second step is to build a system feedback model and a feedback entity library to clarify the implementation of feedback.Specifically,based on the teaching feedback theory and related models,combined with the research findings of traditional guzheng teaching feedback,a feedback model of the target system is constructed to clarify the feedback implementation path,and a feedback entity library is constructed based on the effectiveness and relevance of feedback types to determine the type of feedback implementation.The third step is to build a feedback function prototype to achieve the basic feedback function of the system.Combined with the feedback research conclusion of traditional zither teaching,the system feedback function module including data capture,gesture recognition,correct and wrong judgment,and adaptive feedback function sub modules is constructed by applying gesture recognition technology and Leap motion sensor,and the system feedback function prototype is constructed based on Processing to realize the basic feedback function.Finally,design and experimental verification of the Guzheng fingering auxiliary practice system.Specifically,it includes observing and mining user demand points and opportunity points under the design dimension through user research scenarios,and conducting system and auxiliary practice service design.Subsequently,experimental validation was conducted on the effectiveness of auxiliary exercises and user experience dimensions,and positive results were obtained.Based on gesture recognition technology,this paper provides auxiliary practice services for Guzheng beginners in the independent practice link after class around teaching feedback,and effectively improves the practice efficiency of beginners in the independent practice link after class.This system not only enhances beginners’ sense of achievement in learning,but also enhances the intelligence level of guzheng teaching,which is more conducive to the development of the guzheng teaching market and the dissemination of traditional culture..
