Every art-work has a different perceptual aspect that is related to some issues such as aesthetic perception and knowledge of users. The important point is how users get that and the difference between architectural perception and users that is a controversial issue in modern architecture and cause disagreement between users and designers. According to the importance of vernacular architecture and the need to adapt to its pattern with modern architecture, this paper aimed to evaluate principles of visual Gestalt and aesthetics (...) between users and designers (non-experts and experts1) in the traditional live district in Dezful city in Iran. The methodology of this research is combined with descriptive-surveying methods and field and library studies. So, a semi-structural interview by using a targeted questionnaire was distributed to the experts and non-experts to quantify the differences, and by describing and analyzing these data by SPSS statistical software, the root of the differences between these groups was identified. Due to the analysis of the data, besides searching, studying, and being in that district, two types of questionnaires between users and designers have been used. The result of this study shows that in the ancient city of Dezful, the opinions of experts and users also differ in terms of aesthetic perception so that for users, shape, and context, and experts, symmetry is the first principle. So unexpectedly, it can be argued that sensible visual Gestalt principles, such as symmetry and closure for experts, are of the highest importance, while these principles are of less importance to the user group. The findings of this study made it possible to compare the views and opinions of people and experts. It makes clear the difference between the perception criteria of those who create the landscape and the people who are confronted with and live in the environment. (shrink)
