When creating apps for a spatial environment, like with Apple's Vision Pro, designers aim to ensure that everything remains easy to see and use, regardless of how close or far the window is from users. In simpler terms, the interfaces should scale well and maintain their clarity. This is where points play a crucial role.

If you have experience in other kinds of design, you're probably already familiar with points. They adjust as windows or elements move closer or farther from users, safeguarding legibility and functionality. For instance, if an object is designed to be 10 points at one meter, it will appear twice as large at half a meter, and half as large at two meters. This principle is essential in preserving a consistent visual experience within a 3D space.

Designing with points ensures that users have a seamless experience.

Think of it as zooming in or out on a photo — the entire image expands or contracts, yet it continues to look like the same image. This concept applies to designs in spatial apps, making them feel more natural and user-friendly, even in a 3D environment.^[[1]]
