At its best, virtual reality is one of the most immersive forms of entertainment. At its worst, VR makes its users feel motion sick in a matter of seconds. Why do some people get really sick inside VR? It begins with the disconnect between what the eyes see and what the brain processes, or dissonance. When you’re sitting in a chair in real life but you’re moving forward in VR, chances are you’re not going to feel great pretty quickly. Developers have created quite a few ways to navigate VR environments that reduces the dissonance between the eyes and the brain. First we’re going to examine the traversal method that only those with the strongest stomachs can handle and finally we’ll examine a few methods that heighten immersion. This is the traversal method that some people can handle If you enjoy gaming and you have a strong stomach, you’ll love the . Here’s how traversal works in this game: You hold the Oculus Touch controllers in your hands and you push a joystick forward (or backward) to move yourself.

Tell that to the pro gamers of Onward though, who seem to be able to handle this Forward movement in Onward These are a few traversal methods that heighten immersion Traversal in cockpit experiences, that use teleportation, or that use a few over-the-shoulder third-person hybrids have the ability to heighten immersion. We’ll examine each of these together. : Cockpit Pros: Stable, immersive experience with a clear expectations Cons: Limited freedom of movement The cockpit is a . You sit in a cockpit, typically a sci-fi spaceship, and you press a button to move forward.

Elite: Dangerous : Teleportation Pros: You can “walk” around and navigate a whole environment Cons: Have to spend mental energy actively deciding every step you take This is one of the most common implementations of traversal. You hold a trigger forward then press a button to teleport to the location that you want to be at. It’s a good bridge option that eliminates motion sickness at the cost of immersion. You know theoretically that you’re in the experience but it doesn’t completely fool the brain. It’s a somewhat unnatural movement that takes a big cognitive load, since you have to actively choose where you want to go every time. Teleportation in Obduction Paired with most of these traversal methods is a tap-to-look option. In Obduction, you can tap your left joystick left and right in order to look around. This is an alternative for folks where head movement might cause motion sickness. Tap-to-look in Obduction There are a few traversal methods that combine a few of the elements from those above.
