The Effect of Near Viewing on Visual Attention Performance in Mixed Reality

Abstract

This study examines how vergence-accommodation conflict affects visual attention in Mixed Reality. In a within-subjects experiment comparing HoloLens 2 with 2D displays, participants showed poorer hit rates and higher miss/false rates in MR, with increased fatigue, eye irritation, and headache. Findings suggest that near-viewing MR negatively impacts visual performance despite growing user tolerance.
