A critical aspect of human-centered design is to consider users’ field of view. With devices like Vision Pro, users encounter their digital environment within their natural visual range, which is approximately 180 degrees horizontally and 120 degrees vertically. When we place content, it's important to remember that users can see and focus best on the content that's straight ahead — approximately 30 to 60 degrees from the center of their vision. This is where you'll want to put key content and interactions.

Landscape layouts should fit in this central area comfortably, and avoid having important details too far to the sides where they can be hard to see. The scale of objects is another vital consideration. Elements should be large enough to interact with and read easily, but not so large that they overwhelm the field of view or make users move their heads excessively.

Remember, designing for spatial computing isn't just about immersion — it's also about considering what's comfortable, accessible, and practical for your users.
