Xtended (XR) / Mixed (MR) Reality:  Virtual or Augmented

Virtual Reality

Aliasing and oversampling

Nothing is real...

• CAS - Contrast-Adaptive Sharpening (AMD)
• FSR / NIS - FidelityFX Super Resolution (AMD) / NVIDIA Image Scaling

Xtended /Mixed Reality

Some physical objects rendered in virtual space
or some virtual objects superimposed on real space rendition (3D video).

HMD

models

• Samsung Odyssey+ HMD
  Pleasant display, but not enough resolution.
  Steam/steamapps/common/MixedRealityVRDriver/resources/settings/default.vrsettings
Steam/config/steamvr.vrsettings
• HP Reverb G1 HMD
  Sharp only at the center; poor prescription lens support.
• Somnium VR1 (and Somnium Space metadata)
  Good enough for both long term virtual desktop use and sims?  SteamVR tracking
• Quest 3:  good enough resolution?  marginal passthru
• Samsung Infinite and Immersed Visor

nausea

• visual motion illusion without physical cues
• latency / refresh rate(?)
  few complain of nausea from 24fps film (72fps shutter)
• Vergence-accommodation conflict
  

Issues (for me)

• NOT nausea
• without passthru:  frequent need to remove, reinstall HMD
• prescription eyeglasses may not fit
• switching between (misplaced?) eyeglasses and HMD with prescription inserts
• VR hand controllers are aggravating, easily misplaced and unsuitable for virtual desktop or sims
• custom objects (props) can be introduced to VR (e.g. games) by rendering STL without passthru cameras
• passthru cameras are wanted for real time random objects in games or virtual objects (desktops) into real space
• ability to generate 3D movies using binocular passthru cameras will be a bonus
