UCD Also defined as a process those forces on cognitive factors such as learning, problem solving and human memory, etc. As they come into play during people’s interactions with things. User centered design concerns itself both with usefulness and usability. To design an interface that can induce in the user’s mind a correct model of the system, a user centered approach has to be adopted. User centered design mainly consists of three issues: users steelworkers have to be involved in each step of the design process; the design process is centered on the work activates to be supported rather than on the technological opportunities; Cycles of work analysis-design-prototype-evaluation have to be foreseen. Chapter 5 Development and Evolution of User Interface Aim of User Center Design It cuts the cost and increase user satisfaction and productivity. The main purpose of user centered design is to involving the user from the beginning during design process. The main factors are: Discovering the mental lend of users. Discovering their expectations. Include the user as the part of designi
