I've notice world scale issues with with the Oculus S (HTC Vive seems fine). And my client keeps telling me things "seem small".
I check the IPD, floor height and user height and I experience the same thing. (I double-check the measurements in Rhino 3D)
My test: when I span my arms in Enscape the controllers seem the right distance away... but the objects seem small. For example, I shouldn't be able to span my arms for a 6'8" mattress but I can in Enscape. I don't have the same problem using the HTC Vive using Enscape.
Maybe it has to do with the virtual controller 3D representation being the Oculus Touch? I assume the Touch and Rift S controllers have the same reference point for the trigger.
Has anyone else been getting this feedback giving tours on the Oculus S?
Next steps: I'm going to create a test file with a bunch of objects with marked dimensions and have someone follow me around with a tape measure... I'll report back in a couple of days.
