| Mis-operation is a common problem in the procedure of using a product. To avoid mis-operation, we should know how the product is used in the users’view during product design. Cognition psychology provides many important guiding principles for how users interact with the products, interfaces, systems. It plays an irreplaceable role in revealing the users’thought and supporting the users’operation. Therefore, it is of important significance to study the users in the view of cognition psychology for guiding product design, and building better product concept model.The procedure of user cognition includes visual perception, memory, pattern recognition, etc. When mis-operation occurs, there are some features in the cognition procedure. This paper analyzes the procedure of user cognition and extract several key features that leading to mis-operation:information searching, memory and pattern recognition. Then through the analysis of these features, and incorporating the view of Gestalt psychology which thought the cognition procedure is from global to local, we give a new cognition procedure during the users pattern recognition. We think the cognition goes through3models:first template-based matching model, then prototype-based matching model, and last feature-based matching model. And we verified this procedure using the example of mobile phone UI. According to this cognition procedure, we summarized the features that affect the user interface cognition, and hoping that these features can assist designers to do better product design. |
