Improving user interactions in the design system by employing the nudge theory (case study : refueling process in gas stations)

A concept called perception is used to express the fact that humans can make mistakes. The existence of error in perception shows that what we feel is not necessarily what we understand in our minds. Humans cannot always consciously behave in the same way as a machine. Despite the two types of human and machine behavior that have inherent differences; complex processing in perception and recognition, combined with high speed and accuracy, machine-oriented behavior, and heavy volume of operation, easily leads to user errors. Evaluating these types of errors helps us improve our understanding of human behavior. Design for behavior change is a sub-category of design, which is related to how to shape behavior or use it to influence human behavior. With the emergence of design for behavior change, a powerful method has emerged to enable us to recycle, use energy much more effectively, and change the way we think about social interaction. However, on the topic of design for behavior change, little work has been done to link ideas and techniques across different fields, identify common themes, and present them in a form that can be applied during the design process to develop new products and systems. This research has tried to understand the functioning and limitations of the mind, the formation of behavior, and human errors; Adapted the theory of Saqlameh to the topic of " design for behavior change ". The theory of "Nudge" is a set of simple and low-cost solutions to reduce a wide range of problems caused by human behavior. In other words, Saqlameh's theory ignores laws, regulations, and interventions that change economic incentives, but instead includes a variety of soft functions. By studying the behavior of the "user" and its interactions in design and the "homo sapiens" in nudge theory, it is possible to define the position of the choice architecture for the designer. Because the user often uses the logic of exploration, trial and error, and automatic system while using the products; As a choice architect, the designer can influence the user's behavior by providing effective solutions and guiding the automatic system through brainstorming, and changing the behavior to improve interactions with the designed system. In this research, in addition to collecting information, documents, and library studies, the data obtained from the questionnaire has been examined. Finally, with the help of one of the principles of choice architecture called the principle of error expectation, the refueling process in gas stations was changed and improved; To minimize the placement and forgetting of the fuel card by the user in stations. Such principles help the theory of knowledge with the help of design to change behavior; It can be used in different fields, such as product design, service design, user experience improvement, etc. Design considerations can therefore be part of any behavior change strategy in which design can play a role.
