Evaluating Interfaces and User's Profiles

To show the relevance of the process of User Centered Design, particularly the stages of inquiring and evaluation when involving real user is crucial to thoroughly approach them. It is important to establish consistency of interface design complexity accordingly to the user's experience, to properly drive the design process by defining the level of development of a project. Design Process could be defined as a set of successive steps that aim at finding a solution to interface design. A set of qualitative and quantitative data could be gathered when approaching to Users taking them into account as a systemic element, which in integration with the other subsystem elements (Object, environment and Activity) allows arising information to be identified, collected and with it, feed backing the design process.
