How do I make an app fully immersive?

To make an app fully immersive, you can leverage several techniques and tools presented at WWDC. Here are some key points and sessions that can help you achieve this:

Immersive Space Scene Type:
- Use the immersive space scene type in AVKit to provide customizable progressive immersion. This allows users to set their desired level of immersion using the digital crown on Apple Vision Pro.
- Benefits include custom tint color and pass-through brightness.
- For more details, refer to the session Enhance the immersion of media viewing in custom environments.
Docking and Spatial Video:
- Implement docking for 3D video, where the screen moves backward and enlarges, creating a more immersive experience.
- Spatial video can expand into an immersive presentation, blending seamlessly into the real world.
- For more information, check out the session Build compelling spatial photo and video experiences.
Immersion Styles:
- Use different immersion styles such as mix, progressive, and full to control how your app transitions from a windowed view to a fully immersive experience.
- Customize the initial size of the portal and the supported immersion range.
- For a deep dive, see the session Dive deep into volumes and immersive spaces.
Compositor Services:
- Utilize compositor services to run your game or app as a fully immersive experience where the camera is controlled by the player's head movements.
- This approach may require significant redesign but offers a vivid and engaging experience.
- Learn more in the session Bring your iOS or iPadOS game to visionOS.
Element Fullscreen API:
- Use the Element Fullscreen API to take your media into an exclusive mode view, utilizing the whole display for an immersive experience.
- This is particularly useful for spatial photos and videos.
- For implementation details, refer to the session Optimize for the spatial web.
Sound Design:
- Incorporate meaningful auditory moments with thoughtful sound design to enhance immersion.
- VisionOS adds reverberation based on the physical space, making interactions feel more real.
- For more insights, see the session Design great visionOS apps.

By combining these techniques, you can create a fully immersive app that leverages the capabilities of visionOS and Apple Vision Pro to provide a rich and engaging user experience.
