SUMMARY:Perceptual Requirements for World-Locked Rendering in AR and VR
DESCRIPTION:Technical Communications, Technical Papers\n\nPhillip Guan, Er
 ic Penner, Joel Hegland, Benjamin Letham, and Douglas Lanman (Meta Reality
  Labs Research)\n\nStereoscopic, head-tracked display systems can show use
 rs realistic, world-locked virtual objects and environments. However, disc
 repancies between the rendering pipeline and physical viewing conditions c
 an lead to perceived instability in the rendered content resulting in redu
 ced realism, immersion, and, potentially, visually-induced motion sickness
 . The requirements to achieve perceptually stable world-locked rendering a
 re unknown due to the challenge of constructing a wide field of view, dist
 ortion-free display with highly accurate head- and eye-tracking. In this w
 ork we introduce new hardware and software built upon recently introduced 
 hardware and present a system capable of rendering virtual objects over re
 al-world references without 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 w
 e find an order of magnitude difference in perceptual sensitivity between 
 them. We conclude by comparing study results with an analytic model which 
 examines changes to apparent depth and visual direction in response to cam
 era displacement errors; this analysis identifies visual direction as an i
 mportant consideration for world-locked rendering alongside depth errors f
 rom incorrect disparity.\n\nRegistration Category: Full Access\n\nSession
