Can Kendama VR

We developed “Can Kendama VR,” a kendama training system that assists players in mastering previously unsuccessful kendama skills through 5-minute VR training. By slowing down the speed of time in VR space, the player can play Kendama with the ball which moves slow. From this state, the speed of the ball is gradually faster and closer to normal speed to promote smooth progress with fewer stumbles. In addition, the physical movements of a skilled player were captured and presented as a virtual example in a VR space where the speed of the balls was slowed down. Of the 1128 people who experienced the system, 1087 (96.4%) mastered a kendama trick that they had never successfully performed before. In addition, the results of a comparison between VR kendama training with and without a time adjustment function showed that the former may be more effective in increasing the degree of mastery.
