Objective: The aim of this study is to analyze perceived outdoor advertisement clutter and visual search performance before and after street improvement projects was investigated. Background: To determine the perceived clutter we examined the edge density and the search efficiency as a measure of subjective visual complexity of scenes that were the execution of the improvement project for the outdoor signboard in Seoul, as well as the difference of eye movement pattern. Features of their scanpath with respect to various saccade and fixation parameters were examined to determine whether they behaved with eye movement strategies. Method: 30 Viewers looked at images of outdoor advertisement as their eye movements were recorded using an infra-red recording technique (Tobii x60) during performance of visual search task. The edge density was measured to be determined for complexity of signboard and precisely quantitatively specified. Results: The Longer latencies for previous scenes resulted from a greater fixation count and longer scanpath length needed to locate a target. The results indicate quite clearly that perceived visual clutter correlates with search performance in scenes as assessed both by response time and by eye movement metrics. Conclusion: Eye movements helped corroborate increased visual search efficiency of the new outdoor signboards under visual search tasks. The signboards before the street improvement projects produced more fixations with longer scanpath length, which meant more difficult searching. Application: The results of the research could be applied to design various kinds of signboards.
