| Summary: | In a previous study, we made some new discoveries regarding the use of holograms, particularly as a substitute for classroom instructors. The appropriate hologram tutor character is an important topic to study, considering that the character design as a hologram can significantly influence student learning emotions. In addition, the character design of the hologram tutor is believed to influence the student’s learning experience (LX). Since hologram tutors can have a positive impact on learning sessions, their use should be maintained. However, one of the issues that will hamper the use of hologram tutors in the future is the size of the platform, which is big and challenging to handle. In fact, hologram technology can also utilize the Talking-Head application. This 3D Hologram Talking-head is more manageable due to its smaller size. However, since the 3D Hologram Talking-head only displays the character’s head, the effect of using it on students’ learning emotions remained unclear. Therefore, in the context of this study, we will determine the emotional responses of students to the use of 3D Hologram Talking-Heads with different levels of realism of various characters. © 2023 by the authors.
