Abstract
Abstract. New geospatial technologies and ubiquitous sensing allow new insights into people’s spatial practices and experiences of public spaces. These tools offer new data streams for analysis and interpretation of social phenomena. Mobile augmented reality tools such as smartphones and wearables merge the experience of entangled online and offline spaces in citizen’s daily life. This paper demonstrates a concept that combines eye-tracking tools with innovative mapping in order to enhance the interpretability of real outdoor environmental experiences. Through videogrammetry, a participants’ head posture can be reconstructed. Subsequently the fixations measured through eye-tracking are projected onto a 3D point cloud of the surrounding environment. The presented methodological approach is implemented in the interdisciplinary project DigitAS – The Digital, Affects and Space – which investigates the perception of public places as spaces of recreation, security or fear. The project’s Mixed Methods approach combined qualitative, mobile, in-situ and reconstructive methods with eye-tracking in an outdoor setting. Potentials of the geospatial mapping concept for social science research is discussed.
Highlights
1.1 The Digital, Affects and SpacePeople’s involvement with mobile social media and emerging technologies such as virtual and augmented reality is manifold and increases the complexity of their perception of the world (Dey et al, 2018; Felgenhauer and Gäbler 2018; Lemos 2008; Malpas 2008)
We have shown that the position of participants during eyetracking can be successfully reconstructed in outdoor environments
Despite the availability of photogrammetric software solutions, results indicate that 3D reconstruction based on the scene recordings from eye-tracking glasses can fail if only relying on the video frames acquired during eye-tracking
Summary
1.1 The Digital, Affects and SpacePeople’s involvement with mobile social media and emerging technologies such as virtual and augmented reality is manifold and increases the complexity of their perception of the world (Dey et al, 2018; Felgenhauer and Gäbler 2018; Lemos 2008; Malpas 2008). Augmented Reality (AR) is a field of technologies which imports digital images in real world settings “in such a way that the virtual content is aligned with real world objects, and can be viewed and interacted with in real time” (Dey et al, 2018, 1). Against this background, the interdisciplinary mixed methods development project “The Digital, Affects and Space” (DigitAS) was set up. Core of the project was the implementation of a quasi-experimental field study, which combined mobile eye-tracking with subsequent retrospective think-alouds (Konrad, 2010) to research people’s in-situ use of digital augmented media in public parks and its influence on their perception of such places
