Eye-Tracking the City: Matching the Design of Streetscapes in High-Rise Environments with Users’ Visual Experiences
Abstract: Large cities in the West respond to an ever-increasing shortage of affordable housing by
accelerating the process of urban densification. Amsterdam, for instance, aims to increase its housing
stock by 10 percent in the next 15 years as its population is expected to grow by 20 percent. As in other
cities, it seems inevitable that high-rise buildings with higher skyscrapers than in the past will be built
within the existing urban fabric. Such large-scale (re)development projects shape the conditions for
inhabitants’ eye-level experiences, perception of place and overall well-being. The new hybrid field of
neuroarchitecture offers promising eye-tracking technology and theories for measuring inhabitants’ visual experiences of the city and rethinking the effectiveness of applied design principles across the globe.
In this paper, the ‘classic’ design solutions for creating streetscapes on a human scale in densified areas
have been assessed by eye-tracking 31 participants in a laboratory setting, all of whom viewed photographs of 15 existing streetscapes in high-rise environments. The study drew on theories from the field
of neuroarchitecture and used input from a panel of (landscape) architects and urban designers to design
the research and analyze the eye-tracked patterns. The results indicate that the classic design principles
(horizontal–vertical rhythms and variety; active ground floor; tactile materials) play a significant role
in people’s appreciation of the streetscape and that their attention is unconsciously captured by the
presence of these principles. The absence of the design principles seems to result in a scattered ‘searching’ eye-movement pattern. This also suggests that a coherent design of streetscapes in high-rise environments may contribute to a human scale at eye-level.

The laboratory tests were performed in a closed-off room. Each participant was told that he/she was participating in a study on the future of the city and that eye-tracking technology would be used to record their visual experiences while they viewed a series of images. In the experiment, a Tobii x2-30 compact bar eye-tracker was used together with Sony WH1000XMS3 headphones with noise-cancelling to ensure that noise was kept to a minimum. The images were shown on a 1920 x 1080 pixels screen (full screen), positioned at eye-level with a distance of approximately 60 cm with an angle between eye-tracker and viewer. They were arranged in a slideshow and presented for 5 seconds, using iMotions version 8.1 (Visual Attention Software).
