Subthreshold Jitter in VR Can Induce Visual Discomfort
summary
Psychophysical testing finds peak sensitivity to XY jitter at intermediate frequencies with a 50% detection point around 0.23 mm at 12 Hz (1 m viewing distance). Two in-headset conditions, 0.06 mm and 0.15 mm, are below threshold yet across three 90-minute sessions (38 participants, repeated measures) both subthreshold jitters raise MISC scores over time while pre/post SSQ totals show no significant change, implying time-resolved surveys reveal accumulating discomfort.
