Disney Shows How to Catch a Real Ball in VR
Disney Research and its scientists built a motion capture system that allows people to grab a ball in Virtual Reality just as they would without a VR headset.
Disney Research: The Science behind the Magic
Disney used sensors to track the movement of the ball, the hands, and even the head, and with the help of a motion prediction method, it was possible to visualize the complete trajectory of the ball. This is very science-fiction even for Disney, maybe something Iron-Man would use for the AI of its suit.
The system is both flexible and effective. Test subjects were able to catch the ball very easily, both while looking at the ball in VR, and also by looking at its trajectory or predicted target area.
“We present a system enabling users to accurately catch a real ball while immersed in a virtual reality environment. We 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 our demonstration system, we track the projectile motion of a ball as it is being tossed between users. Using Unscented Kalman Filtering, we generate predictive estimates of the ball’s motion as it approaches the catcher. The predictive assistance visualizations effectively increases user’s senses but can also alter the user’s strategy in catching.”
Disney has no plan in the near future to use this software, but it’s obvious it has many practical applications. From simple VR apps for training to even military purposes. What amazes me the most is that Disney is this interested in Virtual Reality. Good things are to come.
