Application of Human-Computer Interaction in Online Music Education: A Case Study of 'Little Leaf Music Education’

This study explores the application and development of Human-Computer Interaction (HCI) in online education, with a specific focus on online music learning. The research begins by summarizing the evolution of HCI concepts and technologies and analyzing trends in the global digital music industry. Data from 2010 to 2020 indicate that the industry experienced a decline followed by recovery, reaching a total revenue of USD 21.5 billion in 2020, a 7.7% year-on-year increase. This study explores the potential of human-computer interaction in strengthening music education by proposing a new online music application system based on human-computer interaction and evaluating existing software. A case study was conducted using the "Little Leaf Music Education" program as a practical example. Through a participatory action research approach, an HCI course evaluation scale was developed. Questionnaire surveys showed that 66.67% of the 12 students participated in group sessions, and among the four unregistered students, more than 60% attended classes. This indicates that teaching based on HCI has been widely and positively accepted. Further analysis revealed that under the HCI system, both the job submission rate and the pass rate reached 90%. In simulated exams, 75% of students achieved high scores. Moreover, both student and teacher satisfaction rates with HCI classes were recorded at 100%. These findings demonstrate that HCI significantly enriches interactive and hands-on music learning, effectively fostering students’ imagination and creativity. The results provide strong empirical and theoretical support for the future application and advancement of HCI technologies in broader online education contexts.
