What is Tunnelling?

Tunnelling is a technique to reduce sim-sickness in VR games, experiences and apps.

Artificial locomotion in VR - cars, spaceships, first-person "thumbstick" movement - causes sim-sickness in many users. This is a result of a mismatch between the motion they feel and the motion they see. Tunnelling is a highly effective method to reduce this for a large number of users.

It works by fading out peripheral vision. The subconscious uses peripheral vision heavily to interpret motion but the conscious brain largely ignores it - as such, reducing motion in the periphery combats the overall motion disparity users feel without significant information loss.

Additionally, the periphery can be replaced with static imagery to counteract motion even more strongly, "grounding" users in a static reference frame. This is called a "cage" as including a cage or grid maximises this effect.
