Data underlying the BSc thesis: Dynamically Transparent Ghost Instructors and Their Effect on Learning and Skill Retention in Virtual Reality Environments

The bachelor thesis aimed to explore the effect that dynamically transparent ghost instructors can have on the learning and retention of skills in Virtual Reality environments. Ghost instructors are shown to the student as a semi-transparent ghost avatar superimposed on the student's avatar so that students may see and imitate the intended movement from a first-person perspective. The research contrasts the effect of statically transparent (constant transparency) ghost instructors with that of dynamically transparent (transparency depends on student performance) ghost instructors through a user study in which students were taught to trace a 3D curve in a virtual environment. The data collected was logged based on information about this virtual environment, such as student and ghost locations, the error between them, and the resulting ghost transparency. The data files consist of two parts: a partial-CSV header providing trial information, followed by CSV-formatted logs.本学士学位论文旨在探究动态透明幽灵导师（ghost instructors）对虚拟现实（Virtual Reality，VR）环境下技能学习与技能留存效果的影响。所谓幽灵导师，是指叠加于学生虚拟化身之上的半透明幽灵化身，使学生能够以第一人称视角观察并模仿预设动作。本研究通过一项用户实验，对比了静态透明（透明度恒定）幽灵导师与动态透明幽灵导师的教学效果。实验过程中，参与者需在虚拟环境中临摹一条三维曲线。所采集的数据基于该虚拟环境的相关信息进行记录，涵盖学生与幽灵导师的位置、二者间的偏差值，以及最终生成的幽灵导师透明度。数据文件包含两部分：一是用于提供试次信息的部分CSV格式表头，二是紧随其后的CSV格式日志数据。
