“…Related researchers have applied AR technology as multimedia in various types of teaching topics and educational levels such as use of AR in middle-level students and universities as an interactive media on human anatomy, geomorphology, and astronomy learning (Jamali et al, 2015;Kurniawan et al, 2018;Turan et al, 2018;Yen et al, 2013).
