ABSTRACT
OBJECTIVE:
The aim of this study is to examine the interactive effects of display curvature radius and display size on visual search accuracy, visual search speed, and visual fatigue.BACKGROUND:
Although the advantages of curved displays have been reported, little is known about the interactive effects of display curvature radius and size.METHOD:
Twenty-seven individuals performed visual search tasks at a viewing distance of 50 cm using eight configurations involving four display curvature radii (400R, 600R, 1200R, and flat) and two display sizes (33â³ and 50â³). To simulate curved screens, five flat display panels were horizontally arranged with their centers concentrically repositioned following each display curvature radius.RESULTS:
For accuracy, speed, and fatigue, 33â³-600R and 50â³-600R provided the best or comparable-to-best results, whereas 50â³-flat provided the worst results. For accuracy and fatigue, 33â³-flat was the second worst. The changes in the horizontal field of view and viewing angle due to display curvature as well as the association between effective display curvature radii and empirical horopter (loci of perceived equidistance) can explain these results.CONCLUSION:
The interactive effects of display curvature radius and size were evident for visual search performance and fatigue. Beneficial effects of curved displays were maintained across 33â³ and 50â³, whereas increasing flat display size from 33â³ to 50â³ was detrimental. APPLICATION For visual search tasks at a viewing distance of 50 cm, 33â³-600R and 50â³ 600R displays are recommended, as opposed to 33â³ and 50â³ flat displays. Wide flat displays must be carefully considered for visual display terminal tasks.Key words
