Mapping Cycling Experience in Valence-Arousal Space: A Geometric Approach to Appraisal Heterogeneity

Authors: Ayda Grisiute, Johanna Wörle, Panagiotis Mavros, and Martin Raubal

Published in: LIPIcs, Volume 393, 17th International Conference on Spatial Information Theory (COSIT 2026)

Abstract
In this paper, we argue that heterogeneity in experiential appraisals can function as an informative signal for subjective cycling experience. We introduce a geometric framework to characterize the "shape" of experiential appraisal within a two-dimensional affect space. Using data from a crowd-sourced survey, in which participants (N = 239) evaluated 30 first-person cycling video scenarios, we describe appraisal heterogeneity not only by its overall extent (dispersion), but also by its directional structure (anisotropy), bimodality (polarization), and the diversity of affective categories and environmental cues (entropy). Our findings reveal a structural asymmetry. Negative environments result in a rigid, more linear stress response, whereas positive environments allow for diffuse, multi-polar appraisals. We further find that observer experience modulates the magnitude of dispersion, whereas the direction of appraisal remains relatively stable across demographic subgroups. We propose that this approach can quantitatively distinguish between those environments that are consistently perceived as non-bikeable and those that evoke conflicting interpretations. Our methodology complements user-centric models, such as cycling archetypes, by describing the underlying structure of divergent experiences.

Spatial Nudging: Converging Persuasive Technologies, Spatial Design, and Behavioral Theories

Authors: Ayda Grisiute and Martin Raubal

Published in: LIPIcs, Volume 315, 16th International Conference on Spatial Information Theory (COSIT 2024)

Abstract
This paper presents the Spatial Nudging framework - a theory-based framework that maps out nudging strategies in the mobility domain and refines its existing definitions. We link these strategies by highlighting the role of perceived affordances across physical and digital interventions based on the Nudge Theory and the Theory of Affordances. Furthermore, we propose to use graph representation techniques as a supportive methodology to better align perceived and actual environments, thereby enhancing the intervention strategies' effectiveness. We illustrate the applicability of the Spatial Nudging framework and the supportive methodology in the context of an E-bike City vision. This paper lays the foundation for future research on theoretically integrating physical and digital interventions to promote sustainable mobility.
