The purpose of this study is to investigate the effect of the curved display on visual performance and user experience. Eye-tracking technique and self-report were adopted to assess the visual performance when watching multimedia on the curved display. For visual examination, two curvatures were chosen: flat and curved with a radius equal to 4200 mm. A series of 12 clips were presented, consisting of 2 visual tasks and 10 multimedia video clips. The result revealed an improved visual performance in the curved display, especially in terms of visual search and attention. Participants showed an active scan of visual information for a particular target among distractors and quickly responded to the visual cues. The study provides guidance for an effective visual communication through a curved display and can help manufacturers understand the strength and weakness of different display forms.
This study investigated the benefits of a curved display compared with a flat display, and discovered the optimal radius of curvature for large-size curved television based on the subjective judgment on aesthetics and usability. The experimental results showed that the optimal radius of curvature varies depending on the display size and it increases as the size becomes larger. The curvature with a radius equal to 2000 mm is optimal for a 55-inch television, and the curvature with a radius range between 2000 mm to 3000 mm is appropriate for 65-inch and 75-inch televisions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
