ABSTRACT
User-centered design (UCD) is a broad term used to describe design processes in which the end-users influence how a design takes shape (Abras, et al., 2004). It is both a philosophy and a process. It is a philosophy in that it puts the user in the center of the design process, and it is a process in that it focuses on the cognitive factors that come into play during the interaction of people with objects (C.S. Department of Health & Human Services, 2007). UCD is a comprehensive approach to product development that is based on two fundamental premises: that the design should be focused on users and that a scientific, data-driven or engineering approach to design must be taken.
