ABSTRACT
This study examined the effects of display curvature and task duration on proofreading performance, visual discomfort, visual fatigue, mental workload, and user satisfaction. Five 27â³ rear-screen mock-ups with distinct curvature radii (600R, 1140R, 2000R, 4000R, and flat) were used. Ten individuals per display curvature completed a series of four 15â¯min comparison-proofreading trials at a 600â¯mm viewing distance. Only proofreading speed benefited from display curvature, with 600R providing the highest mean proofreading speed. Proofreading speed increased and accuracy decreased for all display curvatures over the 1â¯h proofreading period. Visual discomfort, visual fatigue, and mental workload increased during the first 15â¯min of proofreading. A decrease in critical fusion frequency during that period indicated increases in visual fatigue and mental workload. A short break between 15â¯min proofreading tasks could be considered to prevent further degradation of task performance and ocular health.
