I didn’t personally experiment with DoF, but will give it a go later i think. However, as far as i understand, DoF/blur can cause sensation of movement especially in the periphial view which causes vection which usally the main cause of sim sickness. So personally i would be carefull with this for prolonged periods of time

Depth of Field (DOF) is not something that you want to use in VR as it can give the user simulation sickness. Because of this, it is not a supported VR feature. The reason for this is that DOF comes from a combination of things like the object’s distance from the camera, the lens that is used and the camera settings (Super high-level explanation of this for simplicity sake).

When using VR, you are trying to simulate the way your eyes work and not how two cameras work so a lot of features that you might normally use, like DOF or vignette camera distortion, for example, will not function as these types of effects do not affect our eyes like they affect cameras. However that is not to say that DOF is not something we see with our eyes, we do, it is just very subtle and not as well defined as a camera might. Because of this DOF will naturally occur in VR when the user tries to focus on objects that are too close or too far way which means you can get a very subtle DOF for free in VR.

Jonas, that is very interesting! And yes, that sensation of movement it causes can be quite unpleasant for me who seldom experiences VR induced sickness. Even just moments is enough to wear me out and need a break. Don’t bother trying it. hehe

Sam, that makes a lot of sense. I think forcing someone to look at the world around them through some of the mentioned “lenses”/effects would definitely cause nausea in the non-VR world. I can’t even try to focus my eyes on my nose for more than a few seconds without inducing a headache.
