“…The findings described here contribute to understanding of visual attention in moving space. Recent studies suggest that the vanishing point of scene structure attracts attention (Borji, Feng, & Lu, 2016;Ueda, Kamakura, & Saiki, 2017). Ueda et al (2017) have demonstrated that vanishing points are likely to attract attention throughout a trial in a visual search; even after an initial fixation to a salient stimulus, eye movements converged on vanishing point.…”

Motion is an important factor in visual information processing. Studies have shown that global optic flow guides attention, but it remains unclear whether this attentional guidance occurs regardless of top-down attentional control settings for another endogenous cue. To address this issue, we developed a visual search paradigm in which a task-irrelevant optic flow starts and stops prior to a visual search task itself. Participants first observed an initial optic flow motion pattern for a brief period; next, they searched a static display for a target amongst multiple distractors. Results showed faster target detection when a target's locus coincided with the implied focus of expansion (FOE) from the preceding optic flow (vs. other loci). Eye-movement analyses revealed that initial saccades were drawn to the FOE during optic flow exposures and that relatively few saccades were needed to find targets contingent to the preceding FOE. The advantage of FOE for finding target occurred even when a salient feature singleton captured attention or when a task-relevant feature singleton was prioritized. Results of six experiments suggest that attentional control settings for a feature singleton do not over-ride a sustained influence of optic flow on attentional guidance.

“…The optic flow might influence attention in a mechanism much in the same way that environmental structure guides attention. Some studies have demonstrated that the vanishing point in a visual scene plays a significant role in gaze guidance under free-viewing and visual search situations (Borji, Feng, & Lu, 2016; Ueda, Kamakura, & Saiki, 2017). Borji et al (2016) showed that the density of fixations surrounding the vanishing point was higher than that surrounding random locations.…”

Objective The objective of this study was to investigate whether an artificial optic flow created by dot motion guides attention in a driving scene. Background To achieve safe driving, it is essential to understand the characteristics of human visual information processing as well as to provide appropriate support for drivers. Past research has demonstrated that expanding optic flow guides visual attention to the focus of expansion. Optic flow is an attractive candidate for use as a cue to direct drivers’ attention toward the significant information. The question addressed concerns whether an artificial optic flow can successfully guide attention even in a traffic situation involving the optic flow that naturally occurs while driving. Method We developed a visual search paradigm embedded in a video of a driving scene. Participants first observed an optic flow motion pattern superimposed on the video for brief period; next, when the optic flow and video ceased, they searched a static display for a target among multiple distractors. Results The target detection was faster when a target’s locus coincided with the implied focus of expansion from the preceding optic flow (vs. other loci). Conclusion The artificial optic flow guides attention and facilitates searching objects at the focus of expansion even when the optic flow was superimposed on a driving scene. Application Optic flow can be an effective cue for guiding drivers’ attention in a traffic situation. This finding contributes to the understanding of visual attention in moving space and helps develop technology for traffic safety.

“…They cover a variety of topics across the spectrum of contemporary search research: the prevalence effect (Horowitz, 2017); the importance of scene structure (Ueda, Kamakura, & Saiki, 2017); haptic search (Kaga, Kawaguchi, Mishina, Kita, & Watanabe, 2017); contextual cueing (Higuchi & Saiki, 2017;Makovski, 2017); foraging (Jóhannesson, Kristjánsson, & Thornton, 2017); inhibition of return (Niimi, Shimada, & Yokosawa, 2017); biological motion (Mayer, Vuong, & Thornton, 2017); and the cognitive effects of mobile phone use (Ito & Kawahara, 2017). They also cover a range of search behaviors, including tactile exploration (Kaga et al, 2017), vision-guided touch responses (Jóhannesson et al, 2017), oculomotor behavior (Ueda et al, 2017), in addition to standard button-press reaction time (RT) and accuracy measures. Some studies focus on fundamental, basic science questions (Higuchi & Saiki, 2017;Makovski, 2017), others are concerned with "use-inspired" questions (Horowitz, 2017;Ito & Kawahara, 2017).…”

“…Recent work has taken a more holistic approach, looking at the role of scene structure (Torralba, Oliva, Castelhano, & Henderson, ) and the spatial relations between items (see next paragraph on contextual cueing). In this issue, Ueda et al () study the role of the vanishing point in photographic scenes as well as highly controlled artificial images. They show that eye fixations tend to cluster around the vanishing point, particularly in urban scenes where the cues to the vanishing point are stronger; the effect was much weaker in natural outdoor scenes.…”
