Kyungah Choi presented her recent work entitled, “Visual Search and Attention: What Eye-Tracking Reveals about Visual Performance in the Curved Display” on SID Display Week 2015 in San Jose, CA. Hyunjoo Bae and Sung-Wook Ju have co-authored the paper. Eye-tracking technique was adopted in their study to obtain objective data for measuring visual performance when watching multimedia on a curved display. They observed an improved visual performance in the curved display, especially in terms of visual search and attention.
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.
