Gestalt theory as the main concept of the research was surveyed ‎to answer why the objects are either seen or not seen in an environment. Objects were ‎evaluated with a visual questionnaire. The results showed the role of inherent ‎features of objects' contribution to their backgrounds. The test was an empirical inquiry ‎and the result of the test will be used for safety design, environmental design, and product ‎design. The data were analyzed using a hierarchical analytical process. The human visual ‎system is the main entrance of visual data presented in our environment. Not only does ‎the system play the function of an active surveillance system that lets us make decisions ‎according to our sensations, but also it has the role of the passive surveillance system for ‎the subliminal stimulus that we cannot understand consciously. To study such a complex ‎system of perception, it is needed to use advanced equipment. However, what we did was ‎using the most available method to study it. %U https://jdt.ut.ac.ir/article_86767_6d786d0f33dfefabee7570ea380d35cb.pdf
