- #7 The red pill would free him from the enslaving control of the machine-generated dream world and allow him to escape into the real world, but living the "truth of reality" is harsher and more difficult. On the other hand, the blue pill would lead him back to stay in the comfortable simulated reality of the Matrix
- #21 The central observation is that the amount by which light rays from an object diverge at the eye’s lens depends on the distance from the object to the eye. If the object is close, the rays diverge at a large angle (see Figure 1, left); if the object is at a medium distance, the rays diverge less (see Figure 1, center); if the object is infinitely far away, the rays are parallel and do not diverge at all. In other words: the closer an object is to the eye, the more the eye’s lens has to bend the incoming light rays to form a sharp image on the retina.
- #22 If we extend the light rays between the intermediate lens and the eye backwards (the fainter lines on the right of Figure 2), we find that they all intersect in a single point behind the real screen. To the eye, it looks exactly like a screen that is farther away and larger (the grey horizontal line on the right of Figure 2). This is called a virtual image. And that’s why viewers can comfortably focus on the screens in HMDs: they are not looking at the real screens, which are too close, but at virtual images of the real screens, which are at a much larger distance.
- #23 Top-down view of how our left and right eyes see different images. Remember, binocular is what we see in reality and in virtual reality. The monocular perspective is what we see when we play video games or develop VR apps on a laptop.
- #34 Amazing collection of VR history https://medium.com/inborn-experience/vr-ar-prototyping-for-everyone-ea6fb8f159b5
- #48 See how the picture below looks strange because we can’t move around in it To create comfortable immersion it helps to understand depth perception. Depth perception comes from an array of depth cues. These are split up into binocular and monocular cues. Binocular cues provide depth information when viewing a scene with both eyes. Monocular cues provide depth information when viewing a scene with one eye. We use two binocular cues and 15 monocular cues to perceive depth. We use 7X more cues to perceive depth with 1 eye! Understanding how we see depth with 1 eye helps us to build more comfortable VR scenes.
- #50 Familiar size: Borrow from the real world, and size and scale objects so that they look and feel real to the player. Texture gradient: Objects that are farther away or higher up, should have a lighter shader/color than those that appear closer. Motion parallax and Occultation: Consider how to place one object in front of another to create a sense of depth.

- #64 Imagine standing on a mountain, looking up and around with a clear view of the sky and clouds surrounding you. This is our real-world skybox. It’s what we perceive as far as the eye can see. It’s all around us, above and to the horizon in every direction. It’s our backdrop. As a design element, the skybox is really just a sphere of imagery that can be made from a photo, texture, or rendered artwork. When it’s placed in a scene, it extends out to infinity without a perceivable edge, giving an illusion of depth and reality. The skybox is an essential component in virtual reality design — it’s like a panoramic wrapper that projects an entire background scene onto your interface. https://medium.com/aol-alpha/making-sense-of-skyboxes-in-vr-design-3e9f8fe254d3
- #65 a skybox can really be anything that creates the outermost limits of a scene that you are designing. It could be a solid color that sits behind the menu in a static scene. It could also be a real photograph or a 360˙ video that’s playing. It could be the outer limits of a rendered 3D universe — you could be swimming underwater, floating in outer space, or walking around an animated experience.
- #66 In the foreground you might have interactable 3D objects like buttons the player can touch to deploy a menu, or logs of wood they can pick up, or they run into wild wolves that try to attack them. In the midground, you might have distant messages or scenery that confer scale and depth. And lastly, the skybox resides in the background, expanding out to infinity and wrapping the scene
