SUMMARY:Perceptual Requirements for World-Locked Rendering in AR and VR
DESCRIPTION:Technical Papers\n\nPhillip Guan, Eric Penner, Joel Hegland, B
 enjamin Letham, and Douglas Lanman (Meta Reality Labs Research)\n\nStereos
 copic, head-tracked display systems can show users realistic, world-locked
  virtual objects and environments. However, discrepancies between the rend
 ering pipeline and physical viewing conditions can lead to perceived insta
 bility in the rendered content resulting in reduced realism, immersion, an
 d, potentially, visually-induced motion sickness. The requirements to achi
 eve perceptually stable world-locked rendering are unknown due to the chal
 lenge of constructing a wide field of view, distortion-free display with h
 ighly accurate head- and eye-tracking. In this work we introduce new hardw
 are and software built upon recently introduced hardware and present a sys
 tem capable of rendering virtual objects over real-world references withou
 t perceivable drift under such constraints. The platform is used to study 
 acceptable errors in render camera position for world-locked rendering in 
 augmented and virtual reality scenarios, where we find an order of magnitu
 de difference in perceptual sensitivity between them. We conclude by compa
 ring study results with an analytic model which examines changes to appare
 nt depth and visual direction in response to camera displacement errors; t
 his analysis identifies visual direction as an important consideration for
  world-locked rendering alongside depth errors from incorrect disparity.\n
