ABSTRACT
Our perception of public spaces guides our behavior on them. Understanding which factors shape this perception informs both urban planners, who aim to improve city life, as well as computational models that help us navigate urban spaces. Crowdsourcing games have been employed to evaluate citizens’ perceptions of urban scenes at scale. This work contributes to crowdsourcing studies by evaluating different strategies to aggregate perceptions and rank scenes, as well as investigating the relation of captured perceptions with features of the urban form and the socio-demographic profile of participants.
