Introduction Pastakudasai VR (hereafter “PK-VR”) frames VR development around three simultaneous goals: empathetic narrative invitation, technical perceptual fidelity, and pragmatic production workflows that prioritize repeatable, measurable improvements—what this paper calls “extra quality.” PK-VR is intended for creators building interactive, embodied experiences for head-mounted displays (HMDs), AR-capable headsets, or mixed-reality systems.
Theoretical Foundations PK-VR draws on presence theory (sensorimotor contingency, expectancy violation minimization), perceptual psychology (Weber fractions for audio/visual change detection, focal attention models), and human–computer interaction heuristics (discoverability, error recovery, progressive disclosure). The framework emphasizes minimizing prediction error in sensory feedback and maximizing affordance clarity. pastakudasai vr extra quality
