The urban environment is defined by the interaction between the city morphological characteristics and its physical behavior based on the human interpretation. Contemporary psychology emphasizes the relation between perception and action and shows that perception can be enhanced by the receptor's motion. Basing our work on these principles, we assume that virtual reality techniques, bringing both immersion and interaction to static computer generated images can be of use to study solar effects and therefore daylight ambience. In this paper, we show the methodology for solar effects analysis in both real and virtual world and build demonstrators to compare the emergence of solar effects.
