what were the changes in visionOS2 to Button

In visionOS 2, there have been several updates to the Button component to enhance user interaction and experience. Here are the key changes:

1. Natural Input Enhancements: VisionOS 1 introduced natural input using eye-tracking and finger-tapping for interactions. VisionOS 2 continues to build on this by ensuring that interaction regions are highlighted only when the user's eyes are directed at them, maintaining user privacy by handling highlights outside of Safari (Optimize for the spatial web).

2. Interaction Region Visibility: VisionOS 2 emphasizes the visibility of interaction regions. These regions are now shown directly, helping users to target them more effectively. This is particularly useful for ensuring that tap targets are large enough to be selected properly, even without a different background color (Optimize for the spatial web).

3. Enhanced Scene Understanding: VisionOS 2 has significantly extended the fidelity of scene understanding capabilities, which can impact how buttons and other interactive elements are placed and interacted with in a spatial environment. This includes detecting planes in all orientations and adding room anchors (Platforms State of the Union).

These updates aim to make interactions more intuitive and seamless, leveraging the spatial capabilities of Vision Pro to create a more immersive and user-friendly experience.
