A System for Augmenting Humans’ ability to Learn Kendama Tricks through Virtual Reality Training

Abstract

We developed a system for augmenting humans’ ability to learn Kendama tricks through virtual reality (VR) training. It is often considered to be difficult to play because the ball moves fast, and it is difficult to understand the factors that lead to the success or failure. With this system, we reduced the difficulty of Kendama by slowing down the speed of the ball within a VR space. In addition, this system used the results of detailed measurements of the factors that lead to the success or failure and presented its information to users in an easy-to-understand manner. As a result of the experiment, we confirmed that VR training which used the proposed method has the potential to increase the proficiency of the users in both physical and VR spaces as well as their confidence in succeeding, as compared to VR training which did not.
