摘要

Visual demands from the use of stereoscopic displays results in occupational visual fatigue in the human visual system. This study focused on identifying the effects of alignment error and workload on visual fatigue. Twenty-four participants performed tasks presented in vertical shift, rotational error, and magnification difference alignment errors using 8 ft. × 6 ft. NEC LT silver screen, NEC LT 245 DLP projector and NEC LT 245 Polaroid glasses. There was statistical significant difference between subjective measures of visual fatigue before air traffic control task (BATC) and after air traffic control task (ATC 3), (p < 0.05). Statistical significance was observed for simulator sickness questionnaire (SSQ) and NASA task load index (NASA-TLX) as workload responses between the alignments errors: SSQ (p < 0.05) and NASA-LTX (p < 0.05). Vertical shift alignment error resulted in the least perceptual ratings of visual fatigue and operator workload.
