53.2: Visual Search and Attention: What Eye‐Tracking Reveals about Visual Performance in the Curved Display

Abstract

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.

Preference survey of curvature of large-size displays

“…3 Choi and her colleagues investigated the effect of the curved display on visual performance and user experience based on the eye-tracking technique and self-report, and they revealed an improved visual performance and preference in the curved display compared with flat display. 11 A similar experiment using eye-tracking was carried out in Radvile and Cenys's study, and they discovered that curved display supports faster and easier work. 13 On the aspect of aesthetics, despite that no research has been conducted to evaluate aesthetics of curved display, if has been often claimed that the curved form is more beautiful than the flat form.…”

“…Some previous studies suggested that curved displays might be excellent in both of the two aspects. 11,12 The superiority of curved displays over flat displays in visual comfort was discovered in some of following studies. For example, Shupp's research team presented the benefits of user performance when tiling multiple monitors as a curved shape.…”

“…In this study, usability corresponded to visual comfort when people watch the display, and aesthetic appeal implies the formative stability and beauty of displays. Some previous studies suggested that curved displays might be excellent in both of the two aspects …”

“…Today's modeling capabilities allow the researcher to simulate the color and intensity of light accurately and provide a controlled environment for accountability by keeping the illuminance intensity constant through image processing. 25,26 We have used pictures instead of a real scene because we need to control the variables. It is common to use a real scene in interior studies, but in lightscape studies, modeling is not cost-effective.…”
