- Abstract
Featured Application: Learning how to play the guitar is a challenging task, despite the existence of many didactic materials designed to assist autonomous learning. This paper presents an ad-hoc app based on augmented reality (AR) for self-guided learning on guitar, and provides details of an experimental study designed to compare the learning experiences of guitar students when using the ad-hoc AR-based app designed by the authors versus the more traditional dynamic of face-to-face guitar lessons with a music teacher. Despite being one of the most commonly self-taught instruments, and despite the ready availability of significant amounts of didactic material, the guitar is a challenging instrument to learn. This paper proposes an application based on augmented reality (AR) that is designed to teach beginner students basic musical chords on the guitar, and provides details of the experimental study performed to determine whether the AR methodology produced faster results than traditional one-on-one training with a music teacher. Participants were divided into two groups of the same size. Group 1 consisted of 32 participants who used the AR app to teach themselves guitar, while Group 2, with a further 32 participants, received formal instruction from a music teacher. Results found no differences in learning times between the two groups based on the variables of method and gender. However, participant feedback suggested that there are advantages to the self-taught approach using AR that are worth considering. A system usability scale (SUS) questionnaire was used to measure the usability of the application, obtaining a score of 82.5, which was higher than the average of 68 that indicates an application to be good from a user experience point of view, and satisfied the purpose for which the application was created.
