Positioning a virtual teacher in an MR physical task learning support system

Abstract

Most of the existing physical tasks learning support systems do not show the task’s physical motion in the real world. Because of this, a physical task learning support system showing a 3D virtual teacher model in the real world using mixed reality was developed. Our primary contribution is proving that the virtual teacher model’s position and orientation has a direct effect on the learning process where some settings are more comfortable for the learner than others. Two experiments were conducted to find the effect of the virtual teacher’s position and orientation. The first experiment used to narrow down the large number of possible positions, while the second experiment conducted to evaluate the positions that resulted from the first experiment and to compare them to the results from previous related research. Our experiments show that the virtual teacher’s close side view is the optimal view in such physical tasks learning support system that includes hand moving.
