Urban densification continues unabated, even as the possible consequences for users’ eye-level experiences remain unknown. This study addresses these consequences. In a laboratory setting, images of the NDSM wharf were shown to university students primed for one of three user groups: residents, visitors and passers-by. Their visual experiences were recorded using eye-tracking and analyzed in combination with surveys on self-reported appreciation and restorativeness. On-site surveys were also administered among real users. The results reveal distinct eye-movement patterns that point to the influence of environmental roles and tasks and how architectural qualities steer people’s visual experience, valence and restoration.
The accelerated densification of Western European cities driven by economic growth has major spatial implications for their overall livability. Often, new homes must be built within an existing urban fabric, creating higher density environments. However, the impact on the experience of these high-density environments at eye level remains unstudied and unknown. This chapter reviews two experiments that sought to understand the unconscious reception of streetscapes using eye-tracking technology to investigate the sequence of users’ (visual) experience, their behavior and perception. The research project seeks to establish more ‘evidence-based’ design guidelines for streetscapes in high-rise urban settings.This chapter reviews two experiments that sought to understand the unconscious reception of streetscapes using eye-tracking technology to investigate the sequence of users’ experience, their behavior and perception. Eye-tracking results of Experiment 1 show that the movement of pedestrians, cyclists and cars crossing the street created the most eye fixation for most participants. In general, the eye-tracking results from Experiment 2 show that participants’ eyes followed the length of the facades toward the end of the street and the horizon. The preliminary results suggest that the assessed design principles ‘Active ground floor’ and ‘Ornate facades’ might be important factors in predicting dominant eye patterns. The chapter explores the application of eye-tracking technology in urban design to gain a deeper understanding of the physical-behavioral interrelationship of streetscapes in European high-density built environments. The accelerated densification of Western European cities driven by economic growth has major spatial implications for their overall livability.
In foul decision-making by football referees, visual search is important for gathering task-specific information to determine whether a foul has occurred. Yet, little is known about the visual search behaviours underpinning excellent on-field decisions. The aim of this study was to examine the on-field visual search behaviour of elite and sub-elite football referees when calling a foul during a match. In doing so, we have also compared the accuracy and gaze behaviour for correct and incorrect calls. Elite and sub-elite referees (elite: N = 5, Mage ± SD = 29.8 ± 4.7yrs, Mexperience ± SD = 14.8 ± 3.7yrs; sub-elite: N = 9, Mage ± SD = 23.1 ± 1.6yrs, Mexperience ± SD = 8.4 ± 1.8yrs) officiated an actual football game while wearing a mobile eye-tracker, with on-field visual search behaviour compared between skill levels when calling a foul (Nelite = 66; Nsub−elite = 92). Results revealed that elite referees relied on a higher search rate (more fixations of shorter duration) compared to sub-elites, but with no differences in where they allocated their gaze, indicating that elites searched faster but did not necessarily direct gaze towards different locations. Correct decisions were associated with higher gaze entropy (i.e. less structure). In relying on more structured gaze patterns when making incorrect decisions, referees may fail to pick-up information specific to the foul situation. Referee development programmes might benefit by challenging the speed of information pickup but by avoiding pre-determined gaze patterns to improve the interpretation of fouls and increase the decision-making performance of referees.
