Demo: Learning Ball Juggling in Mixed Reality with Haptic Feedback

Learning complex skills like ball juggling is usually challenging since the balls fall fast in reality. The maturity and rapid development of extended reality (XR) technologies have created opportunities to practice in a virtual environment. The challenge, however, is to connect the virtual world with the real world coherently. We develop a holistic solution with two main components: an XR environment with virtual balls whose falling speed can be adjusted and a haptic glove to provide the sense of catching the ball. By slowing down the falling speed of the balls, the learners can learn individual skills of throwing balls, catching them, and practicing juggling.
