MAXIMIZING THE RIFT’S FIELD OF VIEW
To understand how to maximize the Rift’s field of view, you need to look at how the brain
interprets the images perceived by the eyes. Each eye covers its own field of view, with the
left eye showing more of the world to your left, and the right showing more to your right, with
a large amount of crossover at the center, as shown in Figure 1.21.
Figure 1.21: Left and right field of view
Your brain takes the two images and fuses them into a single panoramic view. This invokes
a sense of depth. Even though actual depth information (parallax) is only really available for
items in the crossover area (see Figure 1.22), the overall sense of depth ends up being greater
than the sum of the parts. Your brain will also take into account other cues such as lighting,
the size of familiar objects and small object movements relative to one another when the point
of view changes, such as when you move your head.
