摘要:This article about signs of urban environmental perception was developed in the city of Medianeira, Southwestern Paraná – Brazil. Part of perceptive information of local social actors was obtained by means of analysis of photographic images with the use of a new investigation instrument that we named Game of the Perception. The activity of the Game encouraged the participating social actors to observe the context of the local environment and perceptually judge practices and habits of the city population, and also experience odd situations on effective practices and use of the environment.
