One of Apple's new announcements has tech experts excited for augmented reality. One chief executive calls it a "game-changer."

Apple unveiled its new operating system for its iPhone and iPad products, the iOS 11, at the Apple Worldwide Developers Conference on Monday.

The system also introduces ARKit, a new framework for developers to more easily build apps that use augmented reality: the tech that allows devices to display computer-generated images over the real world.

"By blending digital objects and information with the environment around you, augmented reality takes apps beyond the screen, freeing them to interact with the real world in entirely new ways," the tech giant said on its preview website.
