However, it comes with a cost of considerably significant efforts and time commitment. The challenge in- tensifies when dealing with languages characterized by distinctive scripts, such as Hangeul in Korean language. The requisite mastery of Hangeul characters precedes the exploration of fundamental linguistic elements, including grammar, pronunciation, speaking, and writing. In this research, we propose an innovative, immersive, and interactive methodology for Hangeul acquisition employing vir- tual reality (VR). Our study transports participants into a virtual environment, guided by a gamification framework designed to facilitate Hangeul learning. Par- ticipants are able to learn basic pronunciation, listening, and Hangeul writing, three fundamental aspects of learning the Korean alphabet. Empirical findings from our experiments show the potential of its usage, indicated by its system usability scale (SUS) of 74.4. This is an open access article under the CC BY-SA license.

INTRODUCTION Learning a foreign language is a part of modern world requirements, as we need to interact and com- municate with colleagues of different backgrounds. Traditional learning is often seen as uninteresting by lan- guage learners. In recent decades, the use of virtual reality (VR) in language learning has increased, mainly attributed to the increase in the motivation and engagement of the learners [1]. For education in general, VR has shown positive attainment of learning outcomes [2], [3], mainly because students can learn interactively with the subjects unlike the passive traditional methods [4], [5]. VR enables immersive learning that helps to improve students’ enjoyment [6], [7] and long-term retention [8]. In addition to providing an authentic learning experience, immersive VR also facilitates students’ cultural engagement [9]. The application of VR is preva- lent in various fields, including medicine [10], engineering [11], agriculture [12], law [13], economics [14], and event military [15], to name a view. Among many fields of education, foreign language learning is highly relevant to many learners. Stu- dents learn a new language before studying abroad [16]; employees study a foreign language prior to overseas relocation [17]; or even youngsters are interested in learning a new language for the sake of experiencing a new culture [18]. Regarding language learning, writing is a significant element, particularly writing in the form Journal homepage: http://ijeecs.iaescore.com
