Apple is taking another big technology swing, introducing Friday its new mixed-reality headset, the $3,499 Vision Pro. And not surprisingly, several sports leagues have quickly moved to build apps for the headset and take advantage of this new platform, which seeks to advance the notion of “spatial computing.” But arriving right along with the excitement are a series of pressing questions.

MLB, the NBA, and the PGA Tour were among the leagues to be first movers on a device that allows immersive digital media to be integrated with the real world—a fundamental difference from the more isolating nature of most virtual-reality applications.

Sports offerings within the Vision Pro will include live and archival games in 4K resolution, interactive statistics, and three-dimensional enhanced data visualizations—all controlled with eye tracking, speech recognition, and hand gestures.
