Catching A Real Ball In Virtual Reality

Disney Research Hub present a system enabling users to accurately catch a real ball while immersed in a virtual reality environment. They examine three visualizations: rendering a matching virtual ball, the predicted trajectory of the ball, and a target catching point lying on the predicted trajectory. In their demonstration system, they track the projectile motion of a ball as it is being tossed between users.

 

Using Unscented Kalman Filtering, they can generate predictive estimates of the ball’s motion as it approaches the catcher. The predictive assistance visualizations effectively increases the user’s senses but can also alter the user’s strategy in catching.
