Some places are experienced as unsafe, while some others as attractive and interesting. These affective responses to environments influence people’s daily behavior and decision-making in space, e.g., choosing which route to take, or which place to visit. In this article, we report on a methodology of using people’s affective responses to environments for enhancing computer-based route planning. More specifically, we explore a crowdsourcing approach to model and collect people’s affective responses to environments; an Affect-Space-Model and a mobile application are developed to facilitate this crowdsourcing approach; a routing algorithm (named AffectRoute) is then proposed to aggregate and integrate the collected data for automatic route planning. Evaluation with human participants shows that the routes generated by considering people’s affective responses to environments are significantly preferred over the conventional shortest ones, which are employed in car navigation systems and many online route planners. In conclusion, considering people’s affective responses to environments contributes to the improvement of automatic route planning. The proposed method can be integrated into existing route-planning services (e.g., location-based services) to provide users with more satisfying routing results.

To improve the current state of uncertainty visualization research, certain areas require more input, e.g. the user domain. Users differences and past experiences need to be analysed to understand how they relate with interpretation and understanding of uncertainty in specific fields. This thesis investigates the effects of uncertainty visualization on user decision making and confidence in the decisions made. Extensive literature review was done to identify uncertainty visualization techniques recommended for use in hazard maps. Two methods were selected, intrinsic color value and extrinsic texture overlay. These techniques were incorporated into fictional flood risk maps that were used in an empirical study undertaken by a Kenyan user group. The user group was divided into sub-groups based on profession (geography experts and novices), exper...

These objective GIS data store abstractions of the real world, especially focusing on physical features. However, research on environmental psychology suggests that all stimuli, including large-scale environments, are perceived not only according to physical features, but also in terms of people's affective responses towards them (Russell, 2003). These responses may influence a person's behavior and decision-making in space. For example, some environments might be experienced as stressful with the consequence of avoidance; others might lead to preference and approach (Kaplan & Kaplan, 1989; Nasar, 1984). Although it is well accepted, that people's wellbeing and behavior is influenced by external cues, subjective geo-information has not yet been incorporated in existing geospatial applications, such as in navigation support. Therefore, we propose that in order to p...

On the one hand, human behaviour and perception are influenced by the environment. On the other hand, humans shape their environment with their actions. The application of theories and methods from environmental psychology is crucial for creating sustainable and satisfying living spaces in various fields, like in housing, work environments, mobility or spatial and urban planning. In this article we provide an overview of environmental psychology in Austria by introducing recent and ongoing research projects. Based on the presented topics, we demonstrate the importance of this domain in practice and research, and claim emphasizing the domain’s relevance in practice and academia. 1. Einleitung Die Umweltpsychologie richtet eine psychologische Perspektive auf die Wechselbeziehungen zwischen Mensch und Umwelt. Die Umwelt wird dabei im psychologischen Sinne als die den Menschen umgebende, ausere physisch-materielle und soziokultu...

These interpretations influence daily behavior and decision-making in space. Recently, due to the ubiquitous availability of smartphones and the increasing growth of Web 2.0, crowdsourcing is emerging as a promising approach for collecting and modeling people’s affective responses towards space. In this paper, we illustrate how these affective responses can be crowdsourced, and how these collected datasets can help to study the impact of environmental characteristics on people’s affective responses, as well as how these responses differ among people with different characteristics, background, and contexts.
