Tasarım bakış açısından yanılsama kavramı: Ürün tasarımında optik yanılsamalar üzerine bir çalışma

The word 'Illusion' can be defined as an effect between what our sensory system receives and what our brain interprets about that phenomenon. People mostly think about illusion as a magic, hobby or a psychological experience but it could have more usage that is important too. The most important application of illusion can be found in nature as camouflage, which can also mean the distinction between life and death. Although, the most known illusion among society is optical illusions, it could occur due all of human senses; as well as, tactile illusion, hearing illusion, smell and taste illusion. The field of illusion is very popular and attractive since the ancient times and people have always wondered about the perception received from an illusion. Therefore, at the beginning, it has been decided to have a research in the field illusion and design; while, it is been seen that not much studies in design have been done on this topic. after all the concepts that the researcher thought are put out as a mind map it is recognized that the illusion and design is a huge field of study to be fit in a single thesis. Although we have five major senses, but most of the information from our surroundings are received by the eyes, which making the sight an important part of our lives; thus it is purposed to limit the subject of the study to the theme of optical illusion and product design. Generally, this research aims to find the relation between the optical illusion and the product design. The literature review chapter (second chapter), introduces the nature of optical illusion and discuss the different types of it, which were gathered from books that most of them could be assume as reference books, as well as the most of the recently published research papers, literature and newspaper articles which were found via Internet search to receive the updated data. The chapter of 'illusion and design' (third chapter) is demonstrating the application of optical illusion in products and other designs. At first, a few examples about usage of illusion illustrated by exemplifying camouflage in nature, some masterpieces in art and a few buildings in architecture to see the other usage of optical illusion. Then in the second part, the field of optical illusion in the industrial design is analyzed by given samples. In this part, a model suggestion is made to classify the relationship between optical illusion and product design; designers may use three techniques to apply optical illusion to their products that include, 'Appropriation of illusion in design', 'Design inspired by illusion' and 'Design creating an illusion'. Designers can create or use illusion in their products to attract consumers and make them satisfied throughout their experience of usage. The example collection in this study is based on searching the Internet which has been done in two ways; first is directly accessing to the well-known designer and companies' websites and second is using the keywords such as "illusion and product, illusion and design, op-art and etc." in common search engines. For further studies, the illusion from other senses including, auditory illusion, tactile illusion, tasting and smelling illusion can be a good topic to research not only in product design but also, in the other aspects of design such as safety, packaging, marketing and social design. Besides, more practice based research options can be considered on the same topics by the aid of new generation computer's 3D programs and 3D printers.
