Eye-Tracking the City: Matching the Design of Streetscapes in High-Rise Environments with Users’ Visual Experiences

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.

Archiving new naturals

This project explores and develops methods for open archiving of socalled "new naturals". A number of tools and templates were created to facilitate collaborative, global - but context-aware and localized - documenting and archiving of "new naturals":

Switching modalities in a sentence verification task : ERP evidence for embodied language processing

In an event related potential (ERP) experiment using written language materials only, we investigated a potential modulation of the N400 by the modality switch effect. The modality switch effect occurs when a first sentence, describing a fact grounded in one modality, is followed by a second sentence describing a second fact grounded in a different modality. For example, "A cellar is dark" (visual), was preceded by either another visual property "Ham is pink" or by a tactile property "A mitten is soft." We also investigated whether the modality switch effect occurs for false sentences ("A cellar is light"). We found that, for true sentences, the ERP at the critical word "dark" elicited a significantly greater frontal, early N400-like effect (270-370 ms) when there was a modality mismatch than when there was a modality-match. This pattern was not found for the critical word "light" in false sentences. Results similar to the frontal negativity were obtained in a late time window (500-700 ms). The obtained ERP effect is similar to one previously obtained for pictures. We conclude that in this paradigm we obtained fast access to conceptual properties for modality-matched pairs, which leads to embodiment effects similar to those previously obtained with pictorial stimuli.

Satisfying a conversation with materials for dynamic fabrics

Schön describes the way a designer engages with their materials as a “conversation”. In clothing design this typically involves tangible and situated actions such as draping, ripping, and cutting—actions that evoke responses from the fabric at hand. Dynamic fabrics—surface- changing fabrics that combine digital and physical states— are still novel fashion-design materials. When working with the digital, intangible qualities of these fabrics, how does a dialogue unfold for designers accustomed to working physically with fabrics? In this paper we examine the design process of Phem, a collection of garments that use dynamic fabrics that function similarly to augmented reality. We reflect upon the improvisations required to satisfy a productive dialogue with the digital forms of these materials. We conclude with a discussion that proposes revisiting Schön’s notion of a conversation in the context of digital forms, and use Ingold’s perspectives on making to inform this inquiry.

Wearable Tactile Technology and the Felt-Body, a Paradigm Shift

In this article I explore a perspective that the philosophical concepts of German phenomenologist Hermann Schmitz (*1928) may open up for thinking about the growing practice of wearing textile integrated electronics directly on the body. It is my contention that traditional conceptions of wearing (non-technological) clothing on the body fail to capture the changed situation and I hence suggest a paradigm shift is needed to think about the novel scope of affects that can be related to body-technology communication. Schmitz’s concepts of the perceptive felt body, corporeal communication and emotions as atmospheres perceived as outside, on or close to the ‘material’ body will be elaborated upon to investigate how they may enhance existing notions of bodily perception and human-technology relations. The case study used for this philosophical investigation is found in the Tactile Sleeve for Social Touch, a wearable created by Elitac, HvA and UTwente, which allows sensations of stroking, tapping and touching to be communicated from one person to another across a distance.
